Sustainable Use of Cultural Heritage in the Formation of Healing Environments : A Case Study of a Healthcare Facility on a Historic Urban Site

Seoul National University (SNU) Medical Campus and Hospital has undergone constant changes throughout its history, from its beginnings as the site of Kyungmo Palace, to its later development as Seoul Daehan Hospital. In the process of this change, the campus has become layered with sites of historical and cultural heritage and various architectural styles. This study examines the spatial location of medical/education facilities and their connectivity to heritage sites, and the formation of a “healing environment” that utilizes the historical/cultural heritage of SNU Medical Campus and Hospital, as well as the resulting sustainability of these heritage sites. This is accomplished by analyzing the layout of facilities, the spatial composition of the campus, and historical/cultural factors. The formation of healing environments for healthcare facilities traditionally employs the natural environment, and healing environments in urban areas commonly utilize landscapes. SNU Medical Campus and Hospital is an excellent case study for the future potential of utilizing cultural heritage sites as healing environments. The formation of a healing environment for medical spaces that utilizes the historical and cultural environment gives new meaning to cultural heritage through their sustainable use.


Introduction
Sites of cultural heritage within city centers form continuous relationships with new buildings as a city expands and transforms.As cities form and expand, public architecture-places in which diverse social activities arise-reacts and interacts accordingly with the changing environment, becoming layered with diverse histories and their resulting products.Despite this diversity, healthcare facilities have typically developed with a focus on functionality as well as a rational composition and utilization of space [1].Recently; however, as attention has been drawn to the importance of healing environments, medical spaces have undergone both internal and external spatial transformations.In other words, healthcare facilities require functional and efficient spatial compositions, yet at the same time must provide healing environments for patients; two needs which are often contrary to each other [2].The current research used a heritage-in-health intervention that aimed to provide a therapeutic activity to improve the wellbeing of individuals receiving healthcare as inpatients, outpatients, and home care residents [3].The heritage organizations have been contributing to adult health and general well-being, as well as children and young people's health [4].Healthcare facilities are one of the most time-sensitive facilities; the various changes and developmental patterns of healthcare facilities over time result from, and are related to, the processes of urban spatial transformation.Healing environment refers to buildings that optimize and improve the quality of care, outcomes, and experiences of patients and staff [5,6].
of urban spatial transformation.Healing environment refers to buildings that optimize and improve the quality of care, outcomes, and experiences of patients and staff [5,6].
Healing hospital understanding handled as patient-centered not care-centered defines innovative environmental designs and aims at patient friendly and non-scary hospital environments [7].As a result of this change, some healthcare facilities were erected near cultural heritage sites, forming environments in which modern medical spaces coexist with historical sites.A well-known example of this phenomenon is the Hospital de la Santa Creu i Sant Pau in Barcelona, Spain.(Figure 1).Hospital de la Santa Creui Sant Pau is a highly complex facility that dates back six centuries, making it the oldest hospital in Spain.From Medieval times to the current healthcare model, the Hospital de la Santa Creui Sant Pau is a highly complex facility that dates back six centuries, making it the oldest hospital in Spain.From Medieval times to the current healthcare model, the hospital has relocated on various occasions and has transformed to adapt to the times, relationship between the development of healing environments within healthcare facilities and the sustainability of historical/cultural environments. 1.

Cultural Heritage Sites within SNU Medical Campus and SNU Hospital
Within SNU Medical Campus, there are cultural heritage sites spanning diverse periods, from the Chosun Dynasty to the early modern era and contemporary times.The main cultural heritage sites consist of the site of Kyungmo Palace from the Chosun Dynasty, Seoul Daehan Hospital from the Daehan Empire era, the College of Medicine main building, as well as relics of Korea's modern architecture, such as the main building of SNU Hospital, the College of Dentistry, and the Center for Medical Innovation.Among these, the site of Kyungmo Palace and Seoul Daehan Hospital are listed as Cultural Heritage sites (Table 1).

Cultural Heritage Sites within SNU Medical Campus and SNU Hospital
Within SNU Medical Campus, there are cultural heritage sites spanning diverse periods, from the Chosun Dynasty to the early modern era and contemporary times.The main cultural heritage sites consist of the site of Kyungmo Palace from the Chosun Dynasty, Seoul Daehan Hospital from the Daehan Empire era, the College of Medicine main building, as well as relics of Korea's modern architecture, such as the main building of SNU Hospital, the College of Dentistry, and the Center for Medical Innovation.Among these, the site of Kyungmo Palace and Seoul Daehan Hospital are listed as Cultural Heritage sites (Table 1).Behind the main building of SNU Hospital is the site of Kyungmo Palace, also known as Hamchun Garden.According to the Cultural Heritage Administration, Hamchun Garden was formed when Changkyeong Palace was constructed in 1484-following the Chinese geomantic principles of Feng-Shui, trees were planted and a surrounding wall was built to prohibit people from entering; the site formally became a garden in 1493.The garden was expanded during the reign of Prince Yonsan and a front gate was erected.Afterwards, the site gradually became neglected and for over 140 years was utilized as breeding grounds for horses.After the shrine of Prince Sado was relocated there in 1764 it was called Kyungmo Palace, and in 1785 the surrounding area was reorganized.Later, when the ancestral tablet of Prince Sado, which was originally in Kyungmo Palace, moved to Jongmyo in 1899, Kyungmo palace lost its function and was renamed Kyungmo Hall.In 1900, Yeonghee Hall, a place where the portraits of the Six Wise Ancestors were enshrined, was relocated to the site of Kyungmo Palace.With the founding of Kyeongseong Imperial University during the Japanese colonial occupation, the original form of the site was lost, and after the Korean War, was completely destroyed.Hamchun Garden was one of the most sophisticated structures of the Late Chosun Dynasty; today the sole remnant of the garden is Hamchun Gate [15].
Seoul Daehan Hospital, used today as a medical museum, was built during the Daehan Empire.According to the Cultural Heritage Administration, construction of Seoul Daehan Hospital began in 1907 by the government of the Daehan Empire just outside of Changkyeong Palace on a hill in Hamchun Garden, and was completed in 1908.At first, the facility consisted of a hospital ward, autopsy ward, and a medical school.Today, only the main building remains.In 1908 Seoul Daehan Hospital became the Hospital of the Japanese Government General of Korea and in 1911 the medical school associated with Daehan Hospital became a medical training school of the Government General of Korea.In 1926 the hospital was incorporated into Kyeongseong Imperial University and became a university hospital.After Korea's independence, the hospital building became the main building of SNU College of Medicine's Hospital and in the late 1970s an annex was constructed on the rear of the building; today, the building is used as a Hospital Research Institute and Medical Museum affiliated with SNU Hospital.The two-story building is characterized by a symmetrical form centered on the entrance vestibule, which emphasizes the building's entrance.The building consists of a brick structure cladded in redbrick and granite with a copper roof.The roof of the main building is a trapezoidal hip roof and the towering clock tower in the center of the building was designed in a baroque style.All of these aspects highlight the western character of the building.
In addition to the above Designated Cultural Heritage sites, SNU Medical Campus also consists of preliminary cultural properties-in other words, those that do not meet the 50-year requirement Behind the main building of SNU Hospital is the site of Kyungmo Palace, also known as Hamchun Garden.According to the Cultural Heritage Administration, Hamchun Garden was formed when Changkyeong Palace was constructed in 1484-following the Chinese geomantic principles of Feng-Shui, trees were planted and a surrounding wall was built to prohibit people from entering; the site formally became a garden in 1493.The garden was expanded during the reign of Prince Yonsan and a front gate was erected.Afterwards, the site gradually became neglected and for over 140 years was utilized as breeding grounds for horses.After the shrine of Prince Sado was relocated there in 1764 it was called Kyungmo Palace, and in 1785 the surrounding area was reorganized.Later, when the ancestral tablet of Prince Sado, which was originally in Kyungmo Palace, moved to Jongmyo in 1899, Kyungmo palace lost its function and was renamed Kyungmo Hall.In 1900, Yeonghee Hall, a place where the portraits of the Six Wise Ancestors were enshrined, was relocated to the site of Kyungmo Palace.With the founding of Kyeongseong Imperial University during the Japanese colonial occupation, the original form of the site was lost, and after the Korean War, was completely destroyed.Hamchun Garden was one of the most sophisticated structures of the Late Chosun Dynasty; today the sole remnant of the garden is Hamchun Gate [15].

The Urban Planning of Seoul National University Medical Campus
Due to the cultural assets located within and around SNU Medical Campus and Hospital, these areas have been designated as a Historical/Cultural Environment Conservation District and Archeological Heritage Preservation District.According to Article 13 of the Cultural Heritage Protection Act and cultural protection regulations of the Seoul City Government, cultural heritage sites as well, as the buffer zone that lies within 100 m at an elevation above 27 degrees from these sites, are protected [20].Because SNU Medical Campus contains the site of Kyungmo Palace, Seoul Daehan Hospital, the former Seoul National University Main Building, and the former Industrial Training Center Main Building, Areas 1 and 2 are set as buffer zones [21].The site of Kyungmo Palace is currently undergoing restoration, while the College of Dentistry, Cancer Hospital, and the Funeral Hall that lie in the vicinity of Changgyeong Palace are located in the first restricted zone (Area 1) of Changgyeong Palace, and; therefore, extension is prohibited.Most areas of SNU Hospital and Medical Campus are included in the second restricted zone (Area 2) of the site of Kyungmo Palace, Seoul Daehan Hospital, or the former Seoul National University Main Building-as "deliberative zones", further development is limited in these areas (Figure 10, Table 4).

The scope of sustainability in healthcare is expanding a more widespread and holistic perspective as to ensure service excellence [25].Healthcare is known to practice environmental sustainability and this approach undertakes not only to improve the environment but to create sustainable design and building techniques for a true healing environment [26].Healthcare managers can implement strategies for multidisciplinary teams to respond to the change and to integrate knowledge, skills, and abilities [27].The Green Guide for Health Care (CMPBS, 2007) integrates environmental and health practices in the areas of health facilities design, construction operations, and maintenance components, and emphasizes the importance of the user perspective along with social support as well as financial and political sustainability areas [28].
The formation of SNU Medical Campus' healing environment can be categorized by two methods; (1) the use of buffer zones around sites of historical and cultural heritage to form healing environments; and (2) the use of historical and cultural environments to create layered landscapes.Examining the spatial composition of SNU Medical Campus in relation to its use of historical and cultural heritage to create healing environments, one can see that the main building of SNU Hospital with the Medical Museum (formerly, Seoul Daehan Hospital).This building, surrounded by large, purely functional hospital buildings, serves as a cultural heritage site and at the same time functions as a museum; the building is an open and exposed space which provides a relaxing and healing environment for the users of SNU Hospital.In addition, the site of Kyungmo Palace, a traditional landscape architecture structure of the Chosun Dynasty, is located behind the main building of SNU Hospital.Unlike the open space formed around the Medical Museum, this space is an enclosed area bounded by the surrounding buildings, such as SNU College of Medicine, School of Nursing, and medical research institutes.This space functions as both a site of historical and cultural heritage and also as a space that can be used by patients and hospital staff for relaxation and strolling.Along with the use of the natural environment around sites of cultural heritage, the formation of a landscape that harmonizes the built environment of the SNU Medical Campus, such as the Medical Museum and SNU Hospital building, also plays an important role in the formation of a healing environment (Figure 12).sustainable design and building techniques for a true healing environment [26].Healthcare managers can implement strategies for multidisciplinary teams to respond to the change and to integrate knowledge, skills, and abilities [27].The Green Guide for Health Care (CMPBS, 2007) integrates environmental and health practices in the areas of health facilities design, construction operations, and maintenance components, and emphasizes the importance of the user perspective along with social support as well as financial and political sustainability areas [28].

In general, the spatial composition of healthcare facilities is oriented on functionality, which leads to an even greater need for creating healing environments for patients; however, this is not easy due to the large amount of funds and space required.The most common method for constructing a healing environment within a healthcare facility is to use the natural environment; however, healthcare facilities in urban areas tend to lack sufficient natural resources, leading many to utilize architectural design and related landscaped spaces [30,31].Therefore, it is necessary to shift this approach by employing the concept of utilizing cultural heritage spaces as healing environments.SNU Medical Campus and Hospital contains diverse historical and cultural heritage sites both within and around its borders; these sites not only exhibit the history of SNU Hospital but also offer a good healing environment for patients, doctors, and hospital staff.Externally, these cultural heritage sites exhibit the valuable cultural legacy of a historic city and, internally, suppress the development of function-oriented, large-scale healthcare facilities due to establishment of buffer zones and Historical/Cultural Environment Conservation Districts, making their continuous expansion possible through the utilization of cultural heritage spaces as healing environments.The formation of healing environments for healthcare facilities traditionally employs the natural environment like plants, water, and light, and healing environments in urban areas commonly utilize landscapes like rooftop gardens.SNU Medical Campus and Hospital is an excellent case study for the future potential of SNU Medical Campus and Hospital use the landscape spaces of Kyungmo Palace and the cultural programs of the Medical Museum to form a healing environment that utilizes Korea's traditional natural and cultural environment.Cultural heritages sites which employ such healing environments reveal the sustainability of historical and cultural sites by emphasizing the value of preservation itself, as well as connecting the healing environments of healthcare facilities with historical and cultural environments.In other words, even if the original function of a historical or cultural heritage is lost or changed, there is historic and appreciative value in preserving their existing form.In addition to their historic value, cultural heritage sites create new value through the formation of important healing environments for healthcare facilities, and as a result, a new aspect of sustainability emerges.

Conclusions
SNU Medical Campus and Hospital have undergone many changes throughout history from Kyungmo Palace to Seoul Daehan Hospital, SNU Yeongeon Campus, and SNU Hospital.With the development of healthcare, the internal and external spaces have continuously expanded and transformed.Throughout the process of this change, the site has become layered with various architectural structures and styles that have accumulated along with the development of the city.The site of Kyungmo Palace represents the traditional architecture of the Chosun Dynasty; the Medical Museum exhibits the architectural style of Korea's Enlightenment Era of the 1900s; the main building of SNU College of Medicine illustrates the architectural style of the Japanese Colonization period, while the main building of SNU Hospital and Center for Medical Innovation display the modern architecture of the 1970's.The main hospital building is positioned in the center with Daehan Hospital in the front, the site of Kyungmo Palace in the rear, and various medical, research, and education facilities surrounding them.In terms of program and scale, the main hospital building forms the center with historical and cultural spaces positioned towards the front and the rear and buildings of modern architecture encircling them.SNU Hospital has long been considered a functional and efficient healthcare facility, while the historic and cultural values of the hospital and Yeongeon Campus have been overlooked.However, the site of Kyungmo Palace can be used not only as the traditional landscape architecture of the Chosun Dynasty, but as the hospital's landscape, while Seoul Daehan Hospital can assume the role of a scenic backdrop.While the value of SNU College of Medicine's main building is important in itself, it also symbolizes the place where SNU once stood; most of the university's buildings having disappeared since its relocation.Daehak-ro is a place where the works of Kim Swoo-geun, Korea's most well-known architect, from the late-1970 are gathered.Thus, SNU Medical Campus and Hospital-a space which harmonizes various historic and cultural heritage sites with state-of-the-art healthcare facilities-is a unique case of an urban medical campus that uses culture and history, the landscape planning of Kyungmo and Changgyeong Palace, a pedestrian-oriented plan, medical and clinical specialization plans, and connection with the neighboring historic and cultural environment in the formation of a healthcare facility healing environment.
This study examines the value and sustainability of providing a healing space within SNU Medical Campus and Hospital from the perspective of historic and cultural environments.Solutions to the problems that may arise in this process, such as the inefficiency of medical, educational, and research facilities, and the conflicting spaces of landscape and heritage conservation, should be considered.Furthermore, it is necessary to break away from the independent and fragmentary value of heritage by analyzing the historic and cultural heritage of the surrounding area and discovering their relationship with the heritage of SNU Hospital, as well pursue further research on the utilization of history's multi-layered and diverse values.
Healing environments for healthcare facilities employ the natural environment, and healing environments in urban areas utilize landscapes.SNU Medical Campus and Hospital is an excellent case study for the future potential of utilizing cultural heritage sites as healing environments.The formation of a healing environment for medical spaces that utilizes the historical and cultural environment gives new meaning to cultural heritage through their sustainable use.
