Culture and Sustainable Tourism: Does the Pair Pay in Medium-Sized Cities?

Undoubtedly, one of the greatest challenges to civilisation today is the need to fulfil commitments to build a just and caring global society. These commitments also apply to the tourism sector. The aim of the article was to determine how to identify opportunities for sustainable tourism development based on cultural heritage in medium-sized cities whose tourism assets can hardly be considered outstanding. This is an even more significant problem, as even in conditions of relatively low tourist traffic cultural tourism may have an unsustainable character if the relevant policy is pursued and the attitude of the inhabitants are inappropriate. The authors proposed to complement the Triple Bottom Line used to assess the sustainability of a destination with the assessment of the local authority’s attitude towards cultural development and characteristics regarding the involvement of the inhabitants. The study has shown that even if the cultural assets of medium-sized cities are not outstanding, they can play a role in tourism development. It is important to remember that their advantage lies in their locality, and that expecting too much of an economic effect of developing tourism can deprive them of this advantage permanently.


Introduction
Undoubtedly, one of the greatest challenges to civilisation today is the need to fulfil commitments to build a just and caring global society [1]. It ascribes dignity to every human being and the actions of societies are directed towards strengthening the foundations of sustainable development in its economic, social, and environmental dimensions. Importantly, this development is carried out from the local scale, through the scale of individual regions and countries, to the global scale [2]. The strategies of sustainable development understood in this way have also been transferred to the tourism industry for several decades [3][4][5][6][7][8][9][10][11][12][13][14]. This may be evidenced, e.g., by the 1992 Rio Declaration on Environment or the first World Conference on Sustainable Tourism organised in 1995. This seems understandable and necessary given the problems resulting from the dynamic development of tourism, including the destruction of the natural and cultural environment due to tourism overload or the loss of cultural identity. In addition to the environmental dimension of sustainable tourism development, its socio-cultural facet has also been recognised over time [15][16][17]. This approach is reflected in European Union (EU) policy and is articulated in the London Declaration of the EC Conference on Sustainable Europe's Cultural Heritage, Council conclusions of 21 May 2014 on cultural heritage as a strategic resource for a sustainable Europe, or other EU documents [18]. Each of these documents stresses that cultural heritage has a significant impact on many areas of economic and regional development, including sustainable tourism, job creation, education, and environment [18].

Research Objective
In a broad perspective, what distinguishes cities and makes them attractive is related to cultural values in general [24,40]. Of course, in the case of cities, the tourist asset may consist in the location or the natural conditions. Attractiveness may also be determined by tourist and non-tourist development and the organisation of tourist traffic connected with tourist promotion and service [41]. However, cultural values still play a prominent role ( Figure 1). This view of the problem was also adopted in this study, with an appreciation and full awareness of the value of comprehensive approaches. They are certainly of great importance, but they do not always allow us to get to the heart of the problem. The aim of the article is to determine how to identify opportunities for sustainable tourism development based on cultural heritage in medium-sized cities whose tourism assets can hardly be considered outstanding. It is assumed here that a prerequisite for achieving the expected results is the appropriate activity and objectives pursued by local actors responsible for creating, developing, making available, disseminating, promoting, and consuming cultural products. The perspective set by local communities is so important that it should be considered as a predictor of how effectively sustainable cultural tourism is developed. Notably, even in conditions of relatively low tourist traffic, cultural tourism may have an unsustainable character if the relevant policy pursued and the attitude of the inhabitants are inappropriate, e.g., focused on economic effects. The question of opportunities for the proper development of tourism certainly concerns a great many entities, and although the conclusions refer to Polish cities, it can be assumed with a certain degree of probability that they are of a more universal nature.
Thus, the article complements the previous research devoted to cultural tourism in cities with a new look at cultural assets and the potential they generate through the prism of the local community, i.e., local authorities and inhabitants responsible for the creation of these assets and their preservation for future generations. This focus on a narrow fragment of reality is imperative to learn and understand perhaps the most important element that can affect the tourist attractiveness of a city, not only as the most creative element, but also as a potentially dangerous one if actions taken in a wrong direction bring disastrous results.
The category of cultural values was filtered to single out components referring to members of the local community (local authorities, representatives of NGOs, inhabitants). They were ascribed various functional characteristics responsible for influencing the shape of the culture in a given place. This element was taken as the primary area of reference.
Other cultural assets that testify to the attractiveness of a city, i.e., facilities and events, are much more often perceived and assessed in terms of their compatibility with the concept of sustainable tourism. In the studies conducted so far [19,[42][43][44], the authors collated indicators to assess the sustainability of the direction of tourism development, including cultural tourism in cities. Their juxtaposition in a single scheme allowed for a The aim of the article is to determine how to identify opportunities for sustainable tourism development based on cultural heritage in medium-sized cities whose tourism assets can hardly be considered outstanding.

The category of cultural values was filtered to single out components referring to members of the local community (local authorities, representatives of NGOs, inhabitants).

Other cultural assets that testify to the attractiveness of a city, i.e., facilities and events, are much more often perceived and assessed in terms of their compatibility with the concept of sustainable tourism. In the studies conducted so far [19,[42][43][44], the authors collated indicators to assess the sustainability of the direction of tourism development, including cultural tourism in cities. Their juxtaposition in a single scheme allowed for a quick diagnosis of potential areas with undesirable characteristics from the perspective of this development direction. The proposed approach attempts to synthesise the previously used TBL approach that considers the direction of development for the economic, socio- ethical, and environmental spheres with the local community perspective. The opinions from this type of cities (collected in the course of the research) are a decisive gauge for assessing the direction in which sustainable cultural tourism develops. The key opinions relate to:

•
The awareness of the existence and importance of cultural heritage (CH); • The perception of CH as a potential for tourism development; • The focus on measurable, tangible results: Economic effect (jobs, income), Image effect (renovations, investment in fixed assets); • Linking CH with sustainable development (support for local producers); • Involvement of residents: Interest in culture, Involvement in the creation of culture, Establishment of local cultural action groups, Involvement in NGOs.
The starting point for research is the conviction that locally generated culture affects the development of sustainable tourism. It is necessary to clarify one matter at this point. Indicators traditionally understood as measures of success, e.g., income growth, scale of tourist inflows, etc., cannot be used to evaluate the observed changes. This is because we assess sustainable tourism, which cannot be quantified in this way. Are we therefore able to propose another way of observing the phenomenon that can help in assessing the situation? In the research undertaken so far, a well-known measuring instrument for sustainable tourism is the Triple Bottom Line (TBL), which was first developed by John Elkington and was later used by businesses and governments [45]. In the tourism industry, the search for a suitable method to determine sustainability at all stages of tourism has made TBL one of the most widely used tools [44]. All components and indicators collected can be used to assess the potential of sustainable cultural heritage tourism (SCHT) destinations. However, some of these indicators are specific and may not be appropriate for use in other types of tourism and contexts, especially when the considerations concern not so much the level of sustainability of cultural tourism itself but rather its potential, analysed in terms of factors determining the direction of development consistent or not with SCHT.
Observing contemporary trends in tourism, it seems necessary to pay attention to places whose tourist attractiveness is not explicitly perceived as high. Paradoxically, in contemporary (post-COVID-19) tourism, they can play a role, perhaps even a significant one. A look from this slightly different perspective shows that the TBL approach is still valid-it was expanded by [42] to measure sustainable tourism in three dimensions (i.e., environmental, economic, and ethical) and further applied in the study by [43] to measure and develop SCHT along four dimensions (i.e., economic activity, social support, management of heritage sites, and the surrounding environment of heritage sites). However, it is definitely necessary, in line with the context mentioned by [19], to redefine individual indicators when research tackles units such as in the present analysis. In the case of a medium-sized city with limited tourist attractiveness, the important elements are those which condition the development of culture in a given place and, by influencing its position, may also determine the development of tourism. Here, the TBL for assessing the destination to determine the degree of sustainability should be supplemented by an assessment of: 1.
the attitude of local authorities to the development of culture-how its role is perceived and what actions follow it-realised and planned (included in development strategies, declared during interviews, cooperation with the environment, e.g., NGOs, and actions taken); 2.
characteristics concerning the involvement of residents (including, among others, in the creation of culture, although also the attitude to culture itself and the level of civic activity). By juxtaposing the observations gathered from these several perspectives, the question of the grounds for the development of sustainable cultural tourism in a given place can be answered. By verifying the tool through interviews and questionnaires (more on this in the section on research methodology), the study additionally generalised the findings from the field research. This allowed the authors to identify some trends, both positive and negative, related to inappropriate or potentially harmful perceptions, understanding, and implementation of the role of cultural tourism.
A proper approach to the problem of the role, activities, and attitudes of the local community, which, through its behaviour and needs, develops culture in its place of residence, requires clarification of several issues described below but is primarily related to the scale of the settlement unit. Therefore, despite the assumption of universality of the research results, they were considered representative for small towns and medium-sized cities, as empirical research confirming the validity of the adopted approach was conducted in settlement units of those sizes.

Research Area-Medium-Sized City-City Scale in the Face of Challenges Arising from Globalisation (First Pillar)
The spatial context associated with the choice of medium-sized cities is the determining factor. The size of the settlement unit translates directly to the problems encountered but also raises certain solutions. Although it is generally the larger cities that have a greater stock of cultural assets [46][47][48][49][50], thus deriving more profit from tourism, smaller cities are perhaps more promising destinations in terms of tourism development trends [51,52]. This is due, e.g., to the sheer impact of the globalisation process on modern tourism [53]. Despite the fact that it affects many different spheres, in tourism it causes a particular problem through the trend towards cultural unification driven by McDonaldisation and artificially generated demand in line with marketing trends. Large cities, which derive huge revenues from tourism and often treat it as a fundamental industry determining the success or failure of their development, seem particularly exposed to this issue. Smaller cities are often paradoxically more likely to have their own small (scale-appropriate) success. It concerns places with individual character, characterised by competitive advantage due to their uniqueness, which is well illustrated by the following quotation: "Globalisation and mass culture have-paradoxically-triggered a demand for different local and individual identities on an unprecedented scale" [54] (p. 156).
Of course, not all medium-sized cities are able to achieve this success. Some cities are likely to succeed, but some are doomed to failure. What seems to determine this difference is their social fabric and the maturity of the inhabitants, consisting in the involvement of the local community and the effort put into creating and supporting local culture. It is worth mentioning at this point a question that, on the surface, concerns the future of the Cittaslow idea and network [55], but is much broader and refers in a universal way to the perspectives of smaller towns in which local culture is an important factor of development. It seems that in the future there are two developmental paths for them: the first is the success of places with an individual character, characterised by a competitive advantage due to their uniqueness, while the second is the emergence of cities very similar to others which have been absorbed by the global trend, universal solutions, and unreflectively adopted patterns. Both these trends will exist in parallel, but those smaller cities that not only consume culture, but above all create it using local resources and the potential of the inhabitants involved, will follow the path of sustainable development.
It is worth recalling Rifkin's observations: "Our globally unsustainable way of life means living in a culture of unsustainability, which is not just about the ecological dimension. We are now turning cultural resources into paid experiences and entertainment. Culture, like nature, can be exploited until the resources are exhausted. When we exploit all the wealth of world culture for quick profits in the commercial sphere and do not allow culture to regenerate and renew itself, then the economy will lose the resources of human experience from which the production of cultural goods draws" [56] (p. 14).

Urban and Cultural Tourism (Second Pillar)
The second issue, which also requires closer examination, is related to the understanding of the term 'urban tourism'. It is referred to in the literature in many different aspects. First of all, according to [57], it should be considered as a complex phenomenon-not only as a set of different forms of activity realised in a specific space, but also as an element shaping the function of a city. The title deliberately mentions this term, which is not only understood as the sum of forms of tourism resulting from tourist assets and development in urban areas, but predominantly as learning about and exploring a place created by people, which is full of meanings and symbols and requires the understanding of various contexts and a certain sensitivity [41]. Such understanding of urban tourism brings us much closer to looking at it through the lens of cultural tourism. This is also confirmed by the results of the research conducted by [58] in New York, which showed that as many as 56% of the visitors to the city were attracted by the desire to learn about its specificity, a specific genius loci built on cultural diversity and a rich cultural offer.
Social changes translating into transformations in the model of contemporary consumption [59,60] have resulted, among other things, in the interesting phenomenon of a blurring of the boundaries between the behaviour of inhabitants and visitors to the city [41]. This indicates that cultural assets can be elements that both groups reach for. Locally created culture (with the inhabitants and their needs in mind) has the value of authenticity which the modern tourist is looking for.

The third element, which is very much intertwined with urban and cultural tourism, sets the conceptual framework for the analysis (see Figure 2). means living in a culture of unsustainability, which is not just about the ecological dimen-sion. We are now turning cultural resources into paid experiences and entertainment. Culture, like nature, can be exploited until the resources are exhausted.

This indicates that cultural assets can be elements that both groups reach for. Locally created culture (with the inhabitants and their needs in mind) has the value of authenticity which the modern tourist is looking for.

Sustainable Urban Tourism and Cultural Tourism (Sustainable Tourism-Third Pillar)
The third element, which is very much intertwined with urban and cultural tourism, sets the conceptual framework for the analysis (see Figure 2).  Given that tourism encompasses economic, ecological, and socio-cultural aspects, sustainable development shifts attention to making tourism economically viable (including for the host community), ecologically neutral, and socially just in the long term [15]. These aspects of sustainability have an impact on the tourist economy, tourism participants (tourists and host communities), and tourist destinations. Therefore, they should be treated as one coherent whole, as only their sensible combination can result in the creation and development of sustainable tourism. Ethics that results from the principles of sustainable development means the recognition that every human being has the same rights in the use of space, both natural and cultural [56]. Symptomatically, the state of research in sustainable urban tourism still refers, as [61] pointed out, to the effects of anthropopressure resulting from tourism intensity. Significant tourist pressure, especially in large cities, has a significant impact on services directly related to tourism (accommodation, cultural, retail), which displace and compete with services geared to serving residents [62,63]. It also affects public services (e.g., waste recovery) and the exploitation of infrastructure (water, energy, telecommunications, public transport, public spaces). The latter are strongly linked to the production of waste (plastic, food, energy, water, etc.) by tourists and the tourism and tourism-related industries, as well as increased demand for water and electricity [64,65]. The high tourist pressure in cities also affects property prices, which soar due to their location in tourist-attractive areas [66][67][68]. Finally, the anthropopressure associated with tourism is not without its impact on air quality, due to gas emissions mainly from modes of transport (coaches, private cars, vans, aviation, cruise ships) [69].
This confirms the observation by [56] that sustainable tourism is mainly perceived as an ecological dimension. However, it is important to treat sustainable tourism also in sociocultural terms on an equal footing with ecological and economic approaches. The need for a comprehensive view of the problem, including the contribution of culture to sustainable tourism development was raised by [36,[70][71][72][73]. As they pointed out, the development of sustainable tourism must also be based on sustainable heritage.
Elsewhere, ref. [74] believed that heritage tourism was the most important and fastest growing tourism niche. Moreover, as noted by [29], "heritage has become a key tool to bring tourism to declining urban and rural areas and to revive neglected industrial regions" (p. 11).
A similar opinion was represented by [75], who acknowledged the occasional problem of overlooking cultural heritage in the sustainable development of cities. If it occurs, it should be considered an important factor in this development. His work also referred to the New Urban Agenda in which culture and cultural heritage occupy an important place in sustainable urban development from the perspective of implementing sustainable consumption and production, as well as urban regeneration. It also emphasises the role of cultural heritage in developing dynamic, sustainable, and inclusive urban economies and in sustaining and supporting them in their gradual transition to higher productivity (paragraphs 45 and 60). The importance of the issue was underlined by many authors who pointed to the rate of growth of this segment of world tourism [76][77][78][79][80][81][82][83][84][85]. In view of the dynamic development of urban tourism, it seems justified to refer to the concept of sustainable development. At the same time, intensified research in this area may contribute to increasing the effectiveness of urban tourism (and cultural tourism) management as well as enhancing the quality of experience of tourists visiting cities [86].
With this in mind, this research focused on establishing the following: 1. Does culture in the city contribute to the creation of new jobs in other sectors (e.g., tourism, trade)? 2.
Has there been any major renovation or revitalisation work done to venues hosting cultural events in the last decade or so? 3.
Were activities related to investments in the field of culture combined with active acquisition of external funds for this purpose? What was the scale of beneficiary involvement? 4.
What was the level of involvement of local communities in participating in activities related to the cultural sector (consumption and creation of culture)?

Research Methodology
The study covered medium-sized cities defined as settlement units with a population between 20,000 and 100,000. The size category adopted may be debatable [87], especially in the perspective of temporal and spatial reference points. For example, over 100 years ago in Poland, the adjective 'small' was attributed to a town with a population of less than 10,000, whereas today it is less than 20,000. In the spatial context, the use of the term 'small' is conditioned by the nature of the existing settlement network of a given country. In relation to Poland, the group of cities with 20,000 to 100,000 inhabitants are referred to as medium-sized, but as mentioned above, the limit value separating large cities from medium-sized cities is debatable [24,88,89].
Research on the broadly-understood cultural sector in relation to sustainable tourism, among other things, began in 2015, which was related to the implementation of the project "Development of small cities in Poland based on the cultural sector" funded by the National Science Centre. The survey covered all medium-sized cities in Poland, i.e., 181 units. Due to the limited availability of some of the data on which this study was based, this figure was accordingly lower.
The first stage of the study focused on establishing the directions for the development of cultural policies in individual cities. The main source of data comprised strategic documents. They were analysed on the assumption that development strategies, as documents outlining directions for action and setting out priority and rational development areas for the future, can be an indicator of both the pursued and planned cultural policy. It should be added here that strategic documents, as opposed to planning documents, are not obligatory at the municipality level in Poland, but each of the examined cities had such a document. Strategic documents were collected and analysed in the context of cultural policy and tourism for all 181 Polish medium-sized cities. The systematic analysis of strategic documents for such a set of cities was the first of its kind in Poland.
In the next stage of the study, a CATI (Computer-Assisted Telephone Interviewing) survey was conducted. This survey covered 177 out of 181 medium-sized cities as four cities (Legionowo, Skierniewice,Świętochłowice, Zamość) did not agree to participate. The interviews were conducted in person and each lasted on average between 30 and 40 min. Responses were coded in an MS Excel form prepared by the authors. The persons interviewed were the directors of the respective departments responsible for culture in the municipal offices. In cases where such an interview was not possible, the interview was conducted with the following officials: • vice-president (or deputy mayor) in charge of cultural affairs in the municipal office; • an employee of the cultural affairs department of the municipal office; • the city secretary.
During each of the interviews, information was obtained on how cultural heritage, the revitalisation or modernisation of cultural facilities are financed and sponsored, and on the significance of cultural events organised in the city and their scope (international, national, regional). The data collected in this way allowed the authors to determine the importance of cultural heritage in each city and the plans for its use for purposes such as tourism. It is also worth mentioning that, as in the case of strategic documents, this was the largest study on the importance of cultural heritage and tourism in Poland in the set of medium-sized cities.
In-depth interviews, designed to complement the CATI survey, were another source of information. Due to the fact that it is a tool for obtaining data of a qualitative nature, it is extremely important here to carry out the procedure of selecting the studied units. Due to the range of data to be collected, the number of such units is usually limited. It was initially assumed that the qualitative research would cover institutions, organisations, and companies related to culture. However, in order to select them for the study, the first focus was to classify the medium-sized cities themselves so that the institutions, organisations, and companies would reflect the broader cultural context in which the cities operate. The classification referred to the CATI survey. Responses to basic two questions (asked also as research questions numbered 1 and 2, see chapter 3) were expressed on a five-point Likert scale, with 'no opinion' in both cases being the basis for excluding a particular city from further analysis. This reduced the number of cities studied to 97. Thus, 53% of all medium-sized cities in Poland were included in this procedure. Such a value was considered sufficient in the context of the multi-stage analysis. The medium-sized cities selected for further analysis depending on their answers to the two questions posed were assigned to one of three categories according to their capability for culture-based development: medium, high, and outstanding.
Given the importance of culture for socio-economic development in its broadest sense, the classification of cities according to their capability for culture-based development was confronted with the actual assessment of this development in the cities under consideration. This level was estimated based on the development benchmark method proposed by [90]. It is one of the methods of numerical taxonomy in which the linear ordering of multidimensional objects relates to a binary relation. It allows the researcher to assess which of the objects in the set is better or worse and to what extent the objects under consideration are similar.
Data for this procedure were obtained from the Local Data Bank of Statistics Poland. The following variables relating to the population, social, and economic situation were taken into account: X1-income per capita in PLN; X2-availability of supermarkets; X3share of working-age people in the total population; X4-birth rate (‰); X5-net internal migration (‰); X6-number of national economy entities entered in the REGON register per 1000 working-age people; X7-number of people working per 1000 residents; X8-share of people of pre-working age in the total population; and X9-number of national economy entities employing less than 9 persons per 10,000 working-age residents. Considering the correlations between the variables, X8 and X9 were eliminated as highly correlated with the other variables and were replicating information. All variables were treated as stimulants due to the nature of the phenomenon analysed.
The variables left in the matrix were transformed according to the statistical procedure of Hellwig's development benchmark method. Therefore, zero unitisation was first carried out as a normalisation transformation according to the formula: where: z ij -the value of the j-th characteristic for the i-th unit after normalisation; x ij -the value of the j-th characteristic for the i-th unit; minx ij -minimum value of the j-th characteristic; O j -the range of the j-th characteristic calculated as the difference between the maximum and minimum values of the characteristic.
Proceeding in this way, the original values of the variables were transformed so that their new values were in the range 0 ≤ z ij ≤ 1.
A hypothetical development benchmark was then constructed against which the distances of the actual points were determined. It should be added here that the development benchmark is established on the basis of the values of the normalised variables in such a way that it takes maximum and minimum values for stimulants and destimulants, respectively. The hypothetical development benchmark was determined by the formula: Next, the taxonomic distances of individual elements, i.e., the analysed cities, from the benchmark object were calculated using the following Euclidean metric: and a synthetic measure: where: s i -the synthetic measure of the distance of the i-th administrative unit from the theoretically determined benchmark; d i0 -the taxonomic distance of the i-th administrative unit from the development benchmark; d 0 -arithmetic mean of the sequence d i0 ; S 0 -standard deviation of the sequence d i0 ; m-the size of the set of characteristics; n-the size of the set of assessed administrative units. Based on the value of the synthetic indicator s i , the medium-sized cities considered were ordered linearly starting from those with the best score to those with the lowest score. Ultimately, the cities were divided taking into account the arithmetic mean (s i ) and the standard deviation (S si ). Proceeding in this way, three classes were separated: • class c (higher level) s i > s i + S si (cities whose distance from the benchmark exceeds s i + S si ; • class b (medium level) s i − S si < s i ≤ s i + S si (cities for which the distance from the benchmark is in the range s i − S si , s i + S si ); • class a (lower level) s i ≤ s i − S si (cities whose distance from the benchmark does not exceed s i − S si ). The cities were then divided along two classification procedures, i.e., the assessment of the capability for culture-based development and the level of socio-economic development ( Table 1). Nine types were identified, with one type-Ic-not represented by any of the cities analysed (Table 2). Table 1. A typology of cities based on the assessment of the capability for culture-based development and the level of socio-economic development. The procedure of classifying and then topologizing the cities was necessary in order to identify one city from each type for the in-depth interviews. The following cities were drawn for in-depth research with representatives of municipal authorities, cultural institutions, NGOs, and companies: Starachowice (Ia), Mielec (Ib), Chełmno (IIa), Pruszków (IIb), Leszno (IIc), Bełchatów (IIIa), Oleśnica (IIIb), Suwałki (IIIc). The main study was preceded by a pilot study conducted in the city of Rumia (IIIb). A total of 40 in-depth interviews were conducted, recorded, and then transcribed for further analysis.

Level of Socio-Economic Development
Another valuable source of information was the www.mapadotacji.gov.pl (accessed on 15 January 2019) website, which lists projects co-financed by European Funds. The data included there come from the Central IT System (SL 2014) and the Project Settlement System (data for [2004][2005][2006]. Using this portal, data was obtained on cultural heritage investments made with the support of the European Social Fund (ESF) for all analysed Polish medium-sized cities. When considering the projects placed on the portal, the main focus was on the expenditures qualified by the beneficiaries as 'culture and arts' and partly 'revitalisation' if the measures included investments in cultural institutions. Data for the assessment of the attitudes and views of residents (representatives of the local community) were collected during surveys designed and carried out in 2018 in Nowe Miasto Lubawskie. The focus was on the way and extent of participation of representatives of Generation Z in activities related to the cultural sector.
The study used an original survey questionnaire consisting of 16 questions answered by high school students. The survey was part of a pilot study within a National Science Centre project "Development of small cities in Poland based on the cultural sector" (grant no. 2015/19/D/HS4/02572). The research sample was 248 people and included 16-to 19-year-olds (the questionnaire was addressed to all students). Assuming a confidence level of 95% and a maximum error of 5%, as well as the number of inhabitants of Nowe Miasto Lubawskie, the minimum sample size was met.

Results
The originality of the adopted research approach stems from the fact of searching for universal solutions in the results of the research conducted on a large sample of objects (medium-sized cities), and not, as usually done, in relation to a selected case study [19,43]. This is due to the assumption that the development of cultural tourism should not only refer to places with attractive anthropogenic values. The potential for the development of cultural tourism is not only shown by well-known places that attract many tourists but also by all places with creations of human civilisation, which can become the subject of exploration by tourists even if they are niche in nature. The low volume of tourist traffic does not exempt those locations from the obligation to design tourism development in a direction consistent with the principles of sustainable and responsible tourism and to analyse the potential for developing cultural tourism in the most desirable form.
The starting point for the conducted research was the assumption that in the case of medium-sized cities with average potential for cultural tourism development, the important factor is the position of culture in a given place. If it is perceived as an important element stimulating development, it has a chance to be properly exhibited, promoted, supported, and thus can play a role in attracting tourists. This 'local climate' is taken as a basic indicator to determine to what extent the potential of a place can be used for the development of cultural tourism. The essence of the research problem is to properly diagnose this 'local climate', which it is worth overlaying on TBL to indicate whether we have the foundations for sustainable tourism development.
Inference about the role attributed to cultural heritage for the development of sustainable tourism was grounded firstly in the analysis of the views, actions, decisions, and opinions expressed by decision makers. This information came from the analysis of strategic documents (visions expressed in the formulated directions of development) and opinions of local authorities that were gathered during interviews, and it concerned the structure of investments, including those co-financed from EU projects. It should be mentioned here that the direct responsibility of local self-governments for the development of culture in Poland began only after 1989. At the same time, the basic elements and shape of the cultural infrastructure network had mostly been created by 1989. The social and economic transformation in Poland, which began in the late 1980s, led to the introduction of market economy mechanisms and the decentralisation of power, as well as of the economy itself. On a local scale, this meant that a new model of development management emerged after decades of no local government structures. It was characterised by decentralisation in the administration of cultural institutions, an increase in their autonomy, the development of acts of law on patronage in the area of culture, and the inclusion of private entities in the performance of tasks in the area of culture and art [91]. This is a very significant change resulting in the inclusion of the local community in the activities in this area, which was accepted as a key element to ensure the possibility of developing sustainable tourism on the basis of culture.
Thus, referring to the analysis of strategic documents, it should be noted that cultural heritage in medium-sized cities in Poland is perceived mainly in terms of its utilitarian significance for tourism development. As the vast majority of strategies show, the promotion of cultural heritage in individual cities is linked to the expectation of an influx of tourists and therefore to profit generation. Such a perspective is highlighted, among others, in the Development Strategy of the Municipality of Andrychów: "The strategy envisages, first of all, further development of recreational and tourist infrastructure and the implementation of original cultural projects which, on the one hand, should translate into increased interest in the Municipality among potential visitors (residents of the Kraków and Upper Silesian agglomerations, foreign tourists, qualified tourists-interested in original natural, cultural, and recreational values, etc.), and, on the other hand, contribute to an increase in the wealth of residents and, consequently, create internal market demand" [92] (p. 73).
Similarly, the development strategy for Skarżysko-Kamienna points to the potential of culture to attract tourists or investors: Cultural promotion of the city shapes its positive external image, attracts not only tourists and participants of cultural events, but also investors [93] (p. 76).
The need to support and promote culture is also recognised by the authors of the development strategy for Racibórz. Based on their experience with the functioning of the cultural sector, they point out that: "Sentimental tourism has a special place in the development of Racibórz. Thanks to its rich cultural and historical traditions, the interest of tourists from the Czech Republic and Germany has been growing significantly year by year. However, this is the generation of older people, who are connected with the town, so it must be assumed that without appropriate promotion there will be a decline in interest in this type of tourism in the future" [94] (p. 13).
Similar expectations and assigned objectives also appear in other development strategies developed for, e.g., Brodnica, Ciechanów, Kluczbork, Tarnobrzeg, Wągrowiec, anḋ Zyrardów. Elsewhere, the development strategy of Chełmno emphasises that "An important development potential for the city is entrepreneurship related to tourism and exploitation of cultural heritage and the so-called creative industries" [95] (p. 30).
Direct references linking culture, tourism, and sustainable development can be found, for example, in the development strategy of Bielawa, where strategic objective no. 4 reads: "Culture as a new potential for the sustainable development of Bielawa". The study argues that "Territorial units striving for sustainable development place emphasis not only on specialisation to ensure competitiveness, but also on the even development of all spheres of activity. This approach guarantees a high degree of flexibility and rapid response in a constantly changing economic and social environment. One of the areas of interest of the city authorities is broadly understood cultural activity . . . " [96] (p. 107).
There were also strategies that included proposals for specific investments based on culture and creating tourist interest that could be used to promote the city. An example of this is the construction of the Trade Factory in Pruszcz Gdański that relates to the amber route and trade with the provinces of the Roman Empire. This investment was completed in 2011. Undoubtedly, it is a unique tourist and archaeological undertaking which is now a tourist destination.
An analysis of the frequency of individual references of cultural heritage to tourism development showed that as many as 112 out of 181 analysed city strategies directly linked these two topics. The need for the development and preservation of cultural heritage was emphasised, with the ultimate aim of boosting tourism.
Unfortunately, in most strategies the emphasis is on developing tourism based on cultural potential because of the projected profits. Investment in culture is not always seen as important to residents and safeguarding their needs. The assumption is that residents will only benefit from the profits generated by cultural tourism. The value of culture as an integrating factor is not perceived, the inhabitants are hardly involved in the creation of culture. Sustainable development is understood as a form of diversifying activities that provides security, mainly economic (labour market flexibility).
Similar results were obtained during the CATI interviews. In this case, municipal representatives were asked how the role of cultural heritage was perceived in their cities, including in relation to tourism. The research revealed that as many as 54.6% of representatives considered cultural heritage in their cities to be important for tourism development, with one in five cities stating 'strongly agree' and one in three stating 'rather agree'. Moreover, based on the answers given, it was found that most frequently (as much as 40%), new jobs in cities related directly or indirectly to cultural heritage were created in the broadly defined tourism sector (Figure 3). A strong relationship between CH and the development of tourism was indicated above all by the representatives of those cities which for a long time have been important tourist destinations on the map of Poland. These included Augustów (an important tourist and leisure centre of northeastern Poland, a health resort), Inowrocław (a health resort), Wejherowo (the cultural centre of Kashubia; in 2013, the seat of the Kashubian Philharmonic was built there-a unique investment), Zakopane, andŻywiec (mountain tourism centres).  Almost 40% of the responses indicated that cultural heritage is influencing tourism development and is expected to continue to do so in the future. In terms of tourism, it was also pointed out that each event organised in the urban space increased the demand for catering services. These would 'incidentally' appear near the location of such event. Some cities indicated specific experiences in generating new jobs based on direct investment in Almost 40% of the responses indicated that cultural heritage is influencing tourism development and is expected to continue to do so in the future. In terms of tourism, it was also pointed out that each event organised in the urban space increased the demand for catering services. These would 'incidentally' appear near the location of such event. Some cities indicated specific experiences in generating new jobs based on direct investment in the cultural sector in conjunction with tourism development. One such example is the city of Grajewo, which by "launching the Milk Museum as part of a cultural institution made it possible to establish a restaurant serving tourists in this museum" (interview with a representative of the Grajewo Municipal Office). Specific experience of the impact of the cultural sector on the development of new jobs is provided by the city of Jarocin where the creation of "a school youth hostel by the Regional Museum in Jarocin in the historic Radoliński Palace gave employment to two people" (interview with a representative of the city of Jarocin). In terms of supporting local artists, city representatives also pointed out the importance of cultural heritage for the organisation of, e.g., fairs during which local handicrafts are promoted or craftsmen can offer the fruits of their labour.
The question regarding the material sphere related to culture was also significant. Respondents indicated whether major renovation or revitalisation work had been carried out on venues hosting cultural events in the past several years. It should be stressed at this point that in the case of medium-sized cities, as well as other cities in Poland, there is a noticeable neglect of the renovation of buildings, housing cultural institutions, and cultural heritage objects themselves, which results from the priority of other needs in post-industrial and post-socialist cities. These cultural infrastructure facilities, as well as monuments, are experiencing almost 20 years of backwardness in conservation care. Despite the signalled problems, the study found that major renovation and revitalisation works related to cultural heritage were carried out in more than 85% of the cities analysed. These renovations focused mainly on the renovation of community and cultural centres (>30%) and other cultural heritage sites (Figure 4).  In second place (19.1% of indications) was the investments in buildings and structures such as theatres, cinemas, auditoria, amphitheatres, etc. Interestingly, the third indication (15.5%) concerned the refurbishment of libraries. Libraries (similar to museums) can create new spaces and organise new activities through which social interaction is possible, and thus they can act as so-called 'third places' [97]. This type of investment, as indicated by research, also increases the number of tourists [98], e.g., coming from the region for various cultural events organised by libraries located in interesting, historic places. One example in the group of analysed cities is the investment connected with the library in Rumia which, according to previous research, is visited by people from other Polish cities who participate in organised events, e.g., meetings with writers [98]. The same applies to the "Preteksty Literary Festival" organised by the Gniezno City Public Library or the "Beautiful Book Festival" held in Piaseczno and co-organised by the Piaseczno Public Library.

With regard to the long-standing neglect of cultural heritage objects and sites in Polish cities in general, there was considerable interest on the part of local authorities in seeking additional resources for CH-related infrastructural investments. Assuming that the budgets of medium-sized cities may have been insufficient for these purposes, the research asked city representatives whether they obtained funding for the development of cultural activities from external sources, including from the EU. As it was shown, in 86% of all cities, external funds were applied for and used in the implementation of tasks in the cultural sector. These funds came from the Marshall Offices of the individual voivodeships, from the Ministry of Culture and National Heritage, from operational programmes under the European Regional Development Fund, the State Film Institute, Norwegian Funds, the Visegrad Fund, and others. Of these external sources, EU funds are a great support for the cultural sector. To emphasise the scale of this support, it should be underlined that between the years 2004 and 2018, Polish medium-sized cities invested PLN 2,614,775,262.53 in the broadly defined culture and national heritage sector, 49.9% of which was obtained from EU funds. Moreover, since the first programming period in which Poland participated, 2004-2006, a dynamic increase in the number of projects in the cultural sector, their total amount, and the share of EU support has been observed ( Figure 5).  (Table 3). Table 3. Level of EU co-financing of projects in medium-sized cities.   (Table 3). Table 3. Level of EU co-financing of projects in medium-sized cities. Within the framework of projects co-financed by the European Funds, the investments related to activities in the CH area were primarily directed at:

Min
• the construction of new or the renovation of existing concert halls, open-air stages, etc.; • tasks aimed at strengthening the cultural potential of the city for the development of tourism; • the organisation of cultural events; • works related to saving cultural heritage; all kinds of works related to the revitalisation of historic districts or individual buildings are also included here, if at least part of the works included improving the provision of cultural services; • the revitalisation or construction of new facilities in which community centres or cultural centres are already located or will be located; • the revitalisation, construction, or adaptation of buildings for library purposes; • the revitalisation of theatre buildings; • the revitalisation or adaptation of buildings for museums or art galleries; • the revitalisation or modernisation of cinemas; • any work within green areas-such as parks-associated with the construction or renovation of amphitheatres; • using the Internet to promote or publicise the cultural resources of cities.
The analysis of the types of projects co-financed from European Funds in the culture and cultural heritage sector in medium-sized cities shows that the largest number of projects in each period was dedicated to preserving cultural heritage ( Figure 6). An example of the impact this type of investment exerts on the development of the cultural sector, and thus on tourism development, is the project implemented in Łowicz, whose direct objective was to develop the cultural base grounded in cultural heritage. The assumed tasks were primarily connected with the organisation of cultural events and the creation of new products, services, and cultural spaces. Next in line were investments combining the protection of heritage with the development of culture and tourism. A fitting example is the conservation and restoration work on the Malbork city wall complex, the aim of which is to give new functions in connection with the creation of the Outdoor Museum of Fortifications.

This included tasks relating to construction and installation works and the supply of equipment in historic buildings and areas of the city. Lębork is one of many examples where such works were carried out on numerous buildings and streets (including the Water Tower, the Blessed Virgin Mary Church, the Sanctuary of St. James, Waryńskiego, Młynarska, Długosza and Armii Krajowej Streets, a fragment of the town walls, the square in Przymurna Street). As a result of the works, the city's tourist attractiveness was increased by, among other things, making buildings accessible to tourists, creating museum rooms, and preparing exhibitions in churches. The vast majority of funds were invested in work focused on the construction or revitalisation of buildings housing museums.
As many as 23 cities applied for and received support from the EU to organise important cultural events, such as the Ada Sari International Vocal Arts Festival and Competition in Nowy Sącz, the Festival of Brass Orchestras in Września, or the Youth Festival organised for the tenth time in Stargard. Major investments, thanks to EU support, also included the restoration of parks. During the renovation works, amphitheatres and spaces for artistic activities were built anew or restored, such as in Sopot where a historic villa and park complex at 1-3 Jakub Goyka Street and part of Park Północny (Northern Park) were adapted for the needs of the ArtIncubator and the public library.
In general, the following centres stand out among the analysed cities in terms of the number of most important investments in the cultural sector as indicated by representatives of local governments during the CATI survey: The selected examples confirm the information obtained during the interviews. Municipal offices and other institutions, including NGOs, apply for and obtain funding for the development of the cultural sector. The thematic diversity of the projects themselves, as well as the scale of their value, makes it only partially possible to assess the impact of this type of co-financing on the possibilities of developing sustainable tourism, but the very fact of applying for funds and undertaking investments should be considered significant. However, it should be noted that the particularly popular activities are those with a material dimension. This, on the one hand, results from the imposed nature of the projects which were the source of funding and, on the other hand, perhaps from the desire of local authorities to implement investments which are relatively easy to plan (compared to soft projects), do not arouse controversy and build a positive image (also of local decision-makers). This is also confirmed by analyses of the impact of investments in cultural and tourism infrastructure co-financed from structural funds on socio-economic development carried out in Poland [99].
In accordance with the adopted assumption, the analysis also covered issues related to the involvement of residents (including, among others, in the creation of culture, although the attitude to culture itself and the level of civic activity are also important) [100]. The survey was therefore designed to answer two questions: (1) about the level of interest in culture and its daily perception and (2) about the involvement in the creation of culture. The study therefore examined whether there was a relationship between the frequency of using the indicated forms of contact with culture and involvement in the creation of cultural events. A cross-analysis of the responses indicates that the relationship studied is weak, revealing itself only in the case of reading ( Figure 7) and attending the theatre ( Figure 8). Respondents who actively participate in culture undertake these activities slightly more often. tourism infrastructure co-financed from structural funds on socio-economic development carried out in Poland [99].

It is difficult to unambiguously assess the culture-forming role of the considered institutions on this basis; however, the cultural centre seems to fulfil its statutory task by attracting young people willing to engage in cultural activities.  Among the cultural institutions that are most important to the respondents, two should be mentioned.

It is important to note that respondents rate the way the library works very high, which indicates that it meets needs and is a meeting place. However, no relationship was found for this institution between frequency of use and involvement in the creation of culture in the city. Such a relationship applies in principle only to one establishment, i.e., the Municipal Cultural Centre (referred to as a community centre in the survey). The key point, however, is that the Centre attracts people interested in becoming active in the cultural field.

The compilation of data collected during the research allowed the authors to assess the possibilities of developing sustainable tourism in medium-sized cities in Poland. The result is a tabular set of assessments verified in the study which are important in determining the potential opportunities for the successful introduction of the principles of sustainable tourism related to CH (Table 4). The collected data show that local authorities feel a particularly strong sense of responsibility for planning and implementing activities aimed at a visible economic impact, such as new jobs or support for local entrepreneurs. They are keen to undertake investments that produce tangible results and that residents associate with the achievements of the authorities ('the authorities built/renovated this'). Such activities are a valuable showcase for the city, but also for individual decision makers seeking re-election. The association of tourism development with CH in accordance with the principle of sustainable development must relate to the sphere of economic satisfaction-this is in no way undermined. However, the research results seem to indicate an overemphasis on this area compared to the others when it comes to the attitudes of some decision-makers. Residents are somewhat less concentrated on economic effects, while those who engage in social activities, e.g., within NGOs, are focused on perceiving the effects of activities from the perspective of social and environmental impact.
to be particularly difficult in relation to intangible heritage, which is often overlooked in tourism and urban marketing studies. However, in a global world where it is so important to respect the principles of sustainability and create an authentic tourism product, each city must take into account its local resources, especially its cultural heritage, in order to build its image.

Summary
The results of the research carried out bring us closer to answering the question of how to preserve the synergies mentioned in the discussion. First of all, it is crucial to state that the opportunities for developing sustainable tourism based on cultural heritage depend on local communities. Two issues in particular are important: the activity of local actors and the objectives set and pursued-these issues will bring tourism development to the desired point from the perspective of sustainability.
In addition, it should be remembered that the scale of tourism is an important element that can make it easier or more difficult to maintain the desired direction, but if we analyse a large set of cities whose tourist attractiveness in terms of cultural resources is average, the potential risks are distributed differently. In such a case, a more important problem is the wrong policy, the focus of the local community on quick profit, the image effect, or the passivity of the inhabitants (both as recipients and creators of culture).
Of course, full altruism or full knowledge and awareness cannot be expected from all members of the local community, but from the perspective of the TBL method in which the economic, socio-ethical, and environmental spheres were juxtaposed with the opinions of local authorities, residents and NGOs, we can see that each group places different emphasis on individual areas (Table 4). This means that each actor has slightly different priorities and thus each sphere remains in focus. In order to achieve success in developing sustainable tourism, it is important to ensure that there is a balance of influence from these three groups. Their subjectivity and cooperation seem to provide an answer to the question of opportunities for the development of sustainable tourism based on cultural heritage.
In this context, the analysed medium-sized cities in Poland are in a special situation as they were arguably underinvested in the sphere of broadly understood culture due to the country's affiliation to the socialist bloc between 1945 and 1989. In contrast to the cities of Western Europe, whose tourist market for decades was subject to the laws of the market, i.e., obtaining the highest profit and remaining under the strong influence of globalisation, post-socialist cities, including in Poland, may now properly create their tourist products by undertaking their delayed investments in culture. They also have the opportunity to steer the target size of tourist streams, tourist capacity, and implement other sustainable tourism principles. Even if their cultural assets are not outstanding, they can play a role in the development of tourism. It is important to remember that their advantage is their locality, and that expecting too much of an economic effect of developing tourism can deprive them of this advantage permanently.
