Roses held profound cultural and economic significance in ancient Greece and Rome, yet comprehensive documentation of their species diversity, cultivation practices, and horticultural innovations remains fragmented across archaeological, iconographic, and textual sources. This multidisciplinary study synthesizes evidence from classical texts, archaeological remains including recently identified rose stem fragments from Oplontis, and iconographic materials—including frescoes, coins, and mosaics—to reconstruct the horticultural systems and cultural landscape of roses in classical antiquity. Analysis of literary sources, particularly Theophrastus’s fourth-century BCE taxonomic descriptions, reveals systematic cultivation of diverse rose varieties with flowers ranging from white to deep crimson, including yellow variants, characterized by morphologies from simple to double forms and valued for fragrance intensity and re-blooming capacity. Archaeological evidence from sites such as Paestum, Pompeii, and Oplontis, including pollen samples, preserved wood fragments with diagnostic prickle patterns, and fresco representations, documents commercial rose production and specialized cultivation techniques that demonstrate significantly greater morphological diversity than textual sources alone indicate. Field research and collection documentation establish the origins of Mediterranean rose cultivation, while iconographic analysis identifies roses in religious ceremonies, festivals, and daily life contexts. Textual sources provide detailed propagation methods, seasonal management practices, and evidence of Mediterranean hybridization events, alongside extensive documentation of medicinal and cosmetic applications. Economic analysis reveals specialized trade networks, commercial production centers, and diverse applications in perfumery, garland making, and pharmaceutical industries. This research establishes that Greek and Roman civilizations developed sophisticated rose cultivation systems integrating botanical selection, horticultural innovation, and cultural symbolism that directly influenced medieval and Renaissance practices and informed modern trait categorization systems. These findings demonstrate the foundational role of classical antiquity in European rose heritage, revealing how ancient horticultural knowledge, species diversification through hybridization, and cultivation techniques created an unbroken transmission that shaped contemporary rose industries and established conservation priorities for this horticultural heritage.

This study investigates and compares archaeological site management practices across diverse cultural contexts, focusing on how cultural factors influence preservation, stakeholder involvement, and management strategies. Employing a mixed-methods comparative design, the research integrates field observations, interviews with site managers and local stakeholders, and archival analysis. Three case studies, the Giza Necropolis in Egypt, Madain Saleh in Saudi Arabia, and the Al-Ain Archaeological Sites in the United Arab Emirates, form the empirical foundation for this analysis. Thematic and qualitative comparative analyses are used to identify cross-cultural patterns, challenges, and best practices. The findings reveal that management approaches are profoundly shaped by their respective cultural settings. Regions with strong traditions of community participation, such as Al-Ain, tend to integrate local knowledge and foster sustainable preservation outcomes. In contrast, state-dominated systems, as seen in Egypt and Saudi Arabia, often face constraints related to bureaucratic processes and limited local engagement. Across all contexts, factors such as governance structures, funding mechanisms, and cultural attitudes toward heritage emerge as decisive in shaping management effectiveness and sustainability. The results offer essential perspectives for the strategy of engaging local communities in the management of archaeological sites, and may be beneficial for implementation in other Arab countries.

Urban expansion causes increasing risks to archaeological heritage and yet few studies have systematically analyzed multi-site urban change using consistent temporal datasets and standardized methods. In this sense, this study addresses this gap by applying a multi-temporal urban change detection framework to the Memphis region, focusing on the Abu Gurab, Abusir and Saqqara sites. To conduct this research, high-resolution satellite imagery from 2004, 2008 and 2025 was processed using harmonized geospatial classification and overlay techniques to quantify built-up area growth and identify zones where modern development threatens key monuments to include the Sun Temples of Userkaf and Nyuserre, and the pyramids of Sahure, Neferirkare and Neferefre. A GIS- and remote sensing-based workflow, combining supervised classification, post-classification comparison and buffer zone analysis, enabled precise monitoring of urban encroachment. Additionally, high-resolution imagery and in situ inspections supported detailed decay mapping of select monuments, using grayscale normalization and false-color analysis to quantify surface deterioration objectively. This approach highlights the progressive impact of urbanization on archaeological structures and provides actionable data for archaeological sites management. Finally, the results contribute to heritage risk assessment, support evidence-based conservation planning, and inform urban planning strategies in line with Sustainable Development Goal 11.4 and the UNESCO Historic Urban Landscape Recommendation (HULR).

The topic of archaeological apothekes, i.e., storage areas not intended for display and not accessible to the public (depositi in Italian), has only recently received the attention it deserves, for reasons related to the history of research methodology. The archiving of archaeological material poses specific problems compared to other categories of material with which the process is generally associated, such as artistic artefacts. Excavation finds consist mainly (and increasingly) of a mass of anonymous, repetitive pottery fragments, not destined to be accessible to the public. The management of these storage facilities poses two sets of problems linked with its archiving: on one hand, its (digital) documentation; on the other hand, its physical arrangement. Both aspects have often been contemplated, but as separate entities by different specialists (archaeologists, conservators, etc.). An adequate approach requires however both aspects to be considered together, for archaeological material only achieves its full value when its context of origin is secure. Only proper management of digital and physical archives can ensure a full understanding of the historical significance of archaeological material. These challenges also apply to the Archaeological Mission of Phaistos, in Crete, where Italian have been active since 1900. The reorganisation of the warehouses in 2024–2025 provided an opportunity to adequately address both the digital archiving of the material and the layout of the warehouses, tackling at the same time the particularly pressing issue in this case of the reuse of ‘legacy data’, which poses problems of standardization. This led also to a new perspective, using old labels and boxes as metadata to reconstruct the methods of archaeological research. The main results however were the creation of a holistic approach to the management of archaeological material and its (written, graphic, photographic, and topographic) documentation through the adoption and implementation of PyArchInit (version 4.9.5), a plug-in of QGIS (version 3.40.7 Bratislava).

This study examines the three pagodas of the Mireuksa Temple Site—the West, East, and Wooden Pagodas—to analyze how material evidence, cultural memory, and representation shape authenticity in architectural heritage. The research aims to clarify how different conservation strategies, including authentic restoration, speculative reconstruction, and digital mediation, influence the construction and communication of cultural memory. Methodologically, the study employs a comparative case analysis grounded in archival research, archaeological records, field observations, and interpretive analysis of digital media practices. The findings indicate three distinct patterns: (1) the West Pagoda demonstrates that evidence-based restoration can maintain both material and historical authenticity; (2) the East Pagoda shows that reconstructions based on limited evidence tend to generate visually convincing yet historically uncertain representations; and (3) the Wooden Pagoda illustrates that digital mediation can effectively communicate lost heritage, but only when its speculative nature is made transparent to the public. The most significant result is that authenticity cannot be defined solely by material survival but must be evaluated through the ethical and transparent communication of historical uncertainty. Based on these insights, the study proposes a conceptual framework of “memory authenticity,” offering heritage practitioners a tool for assessing restoration choices in contexts where architectural evidence is fragmentary or lost. The findings also provide practical implications for heritage management, including evidence-based decision-making, ethically informed digital interpretation, and responsible presentation of reconstructed or hypothetical forms.

Integrated Coastal Zone Management (ICZM) requires multi-scalar, high-resolution monitoring data to effectively address climate change impacts, particularly sea-level rise and accelerated erosion. This study presents an innovative Remote Sensing (RS) and Geoinformatics approach to precisely quantify and contextualize the exposure of sandy beaches. The research focuses on the highly dynamic insular tidal inlet margin of the Pontal Sul da Ilha de Itamaracá, located within a tropical estuarine system in Northeast Brazil that is subject to intense anthropogenic pressure. The methodology of this study integrates high-resolution GNSS-PPK surveys from two seasonal cycles (2017–2018) with a Difference of DEMs (DoD) analysis to precisely quantify seasonal sediment transport. Furthermore, a multi-temporal analysis leverages the Fort Orange Archaeological Site as a stable datum, combining colonial-era maps with modern satellite imagery to trace shoreline evolution. During the 2017–2018 period, maximum erosion (up to ~2.60 m in altimetric losses) affected the southern and central-northern shoreline, while accretion (up to ~2.25 m in altimetric gains) occurred between these erosional sectors and in the northeastern offshore area. This multi-scalar approach provides the robust data necessary for ICZM, effectively prioritizing sustainable, nature-based strategies that align with local administrative capacities. Full article

Mediterranean coastal cultural heritage sites are increasingly threatened by the impacts of climate change, including sea-level rise, coastal erosion, and extreme weather events, which endanger both their physical integrity and their cultural and economic value. Safeguarding these vulnerable cultural assets requires approaches that integrate technological innovation with effective governance and management strategies. This study presents a systematic review of research published between 2000 and 2024, conducted in accordance with PRISMA guidelines to ensure methodological rigor and transparency. Searches were conducted in Scopus, Web of Science, and Google Scholar, limited to English-language studies explicitly addressing coastal cultural heritage in the Mediterranean. A total of 77 studies were analyzed using bibliometric and spatial techniques to examine thematic trends, methodological orientations, and regional patterns. Results reveal a sharp rise in scholarly output after 2014, with Italy, Greece, and Cyprus emerging as dominant contributors. The literature demonstrates a strong emphasis on tangible cultural heritage, particularly archaeological sites and monuments, while cultural landscapes and nature–culture systems receive comparatively limited attention. Methodologically, the field is dominated by digital and technology-driven tools such as GIS, remote sensing, 3D documentation, and climate modelling, with socially grounded and participatory approaches appearing in less than 5% of studies. More than 70% of the reviewed works adopt case study designs, which constrain comparative and generalizable insights. In contrast, a predominance of future-oriented assessments highlights a persistent lack of present-day monitoring and baseline data. Collectively, these findings clarify the paper’s exclusive focus on coastal cultural heritage, underscore the need to broaden geographical coverage, integrate socio-institutional dimensions with environmental diagnostics, and prioritize empirical, present-focused approaches. In this direction, future research will advance an integrated framework for assessing coastal vulnerability at both site-specific and regional scales, supporting proactive and evidence-based conservation planning.

The marginal arid region encompassing the western Nafud in the east to Wadi Tabuk in the west has only been subject to limited archaeological survey. This paper reports on data from a systematic remote sensing survey of the region as part of the Endangered Archaeology in the Middle East and North Africa project, using the results to produce preliminary models of settlement, occupation, and land-use, and contextualising within the broader archaeological landscapes of northern Arabia. It also provides datasets that can be used to outline broad trends in modern disturbances and threats to these sites, in part demonstrating the effectiveness of this approach for producing a cost-effective baseline dataset for the management of heritage sites at a landscape level. While confirming that long-term settlement and agriculture were largely confined to the Wadi Tabuk region from the later prehistoric period onwards, including the identification of a significant new fortified settlement south of Tabuk, it also demonstrates evidence of a broader complex landscape of pastoralism, funerary monuments, and other monumental structures across much of the survey area. Most notably, this area may mark a border zone when geographically distinct distributions of Neolithic-adjacent kites and mustatil meet with minimal overlap. Full article

Recent research has identified a connection between ancient identities and the surrounding landscape during the Roman era in Shropshire, UK. Specifically, archaeological sites associated with distinct identities, characterised by abundant material culture remains, tend to be located in highly visible places. This suggests that their placement was intentional, possibly to signal wealth, status, and territorial control or to oversee slaves and tenants working nearby. This article aims to build on that research by examining the relationship between these identity-linked sites and the broader landscape using ArcGIS techniques. The analysis found no significant correlation between the identities and the wider landscape. Instead, all sites—regardless of identity—are situated near watercourses, Roman roads, and areas that minimise human effort and energy expenditure. These findings imply that ancient groups’ perceptions and management of the landscape varied depending on the spatial scale considered. Full article

The Mystras UNESCO World Heritage Site (MUWHS) is a medieval historical area located on a small hill facing Sparta in the Mediterranean hotspot of the Peloponnese and receives a high number of visitors annually. The main aim of this study is the inventory and analysis of plant species composition and diversity of the Mystras archaeological area, with emphasis on different aspects of its flora, on the specialist endemic plants, and on the generalist ruderal and alien taxa. A high plant species richness was observed, and 321 vascular plant taxa were registered. Most of the taxa are Mediterranean or have a more widespread distribution, and half of them are ruderals. Concerning endemism, 14 Greek and 7 Balkan endemic taxa were registered. As anticipated, the most species-rich plant families recorded in the study area are Asteraceae, Fabaceae, and Poaceae. The total flora is predominantly composed of therophytes, reflecting the site’s Mediterranean climate and disturbance-adapted ecological conditions while the endemic flora is mostly composed of hemicryptophytes. Comparisons of MUWHS plant diversity with four other archaeological sites of the same floristic region of Greece, the Peloponnese, highlighted its high α-diversity on all aspects of its flora and its floristic dissimilarity from the other areas and, additionally, the high plant species richness that is comprised in all five of them. Comparisons of the flora of MUWHS with other Greek and Mediterranean archaeological areas showed significant similarities in the floristic elements considered as deteriogenic for the protected walls and monuments. The findings of our study underscore the urgent need to prioritise the sustainable conservation of archaeological sites such as Mystras. These landscapes are not only cultural monuments but also reservoirs of biodiversity and ecological value. Effective management must, therefore, adopt an integrated approach that balances the preservation of historical structures with the protection of native flora and ecological processes. Full article

UNESCO landscapes, as socio-ecological systems of high natural and cultural value, must be well managed and protected for future generations. The study area of the present research includes the UNESCO site of the Etruscan necropolis of Cerveteri (Central Italy). The main aims of the study are as follows: (1) to compare landscape dynamics of the study area from 1954 to 2023; (2) to assess the potential positive effects of the recognition of the area as a UNESCO site in terms of mitigating landscape change and fragmentation; (3) to identify potential sustainable conservation actions aimed at promoting the connectivity between the site and its landscape context. There was a change in the land cover in the entire study area from 1954 to 2023, which was 23%, with different dynamics at different times, while fragmentation was evident in the UNESCO buffer. This is particularly a concern because it includes the ancient Etruscan city, and it is not subject to adequate protection measures. Finally, this research identified crucial management strategies, including the expansion of the core area to include the ancient city; the restoration of naturalistic connections (e.g., the ancient path) between the city, necropolis, and natural context; and the reforestation of sensitive archaeological areas to mitigate landscape fragmentation.

Protection of coastal cultural heritage is among the most urgent global priorities, as these sites face increasing threats from climate change, sea level rise, and human activity. This study emphasises the value of innovative geospatial tools and data ecosystems for timely risk assessment. The role of land administration systems, geospatial documentation of coastal cultural heritage sites, and the adoption of innovative techniques that combine various methodologies is crucial for timely action. The coastal management infrastructure in Greece is presented, outlining the key public authorities and national legislation, as well as the land administration and geospatial ecosystems and the various available geospatial ecosystems. We profile the Hellenic Cadastre and the Hellenic Archaeological Cadastre along with open geospatial resources, and introduce TRIQUETRA Decision Support System (DSS), produced through the EU’s Horizon project, and a Digital Twin methodology for hazard identification, quantification, and mitigation. Particular emphasis is given to the role of Digital Twin technology, which acts as a continuously updated virtual replica of coastal cultural heritage sites, integrating heterogeneous geospatial datasets such as cadastral information, photogrammetric 3D models, climate projections, and hazard simulations, allowing for stakeholders to test future scenarios of sea level rise, flooding, and erosion, offering an advanced tool for resilience planning. The approach is validated at the coastal archaeological site of Aegina Kolona, where a UAV-based SfM-MVS survey produced using high-resolution photogrammetric outputs, including a dense point cloud exceeding 60 million points, a 5 cm resolution Digital Surface Model, high-resolution orthomosaics with a ground sampling distance of 1 cm and 2.5 cm, and a textured 3D model using more than 6000 nadir and oblique images. These products provided a geospatial infrastructure for flood risk assessment under extreme rainfall events, following a multi-scale hydrologic–hydraulic modelling framework. Island-scale simulations using a 5 m Digital Elevation Model (DEM) were coupled with site-scale modelling based on the high-resolution UAV-derived DEM, allowing for the nested evaluation of water flow, inundation extents, and velocity patterns. This approach revealed spatially variable flood impacts on individual structures, highlighted the sensitivity of the results to watershed delineation and model resolution, and identified critical intervention windows for temporary protection measures. We conclude that integrating land administration systems, open geospatial data, and Digital Twin technology provides a practical pathway to proactive and efficient management, increasing resilience for coastal heritage against climate change threats.

Urbanization poses growing threats to archaeological heritage sites embedded within cities, necessitating innovative monitoring and documentation strategies. This study investigates the use of Unmanned Aerial Vehicle (UAV) photogrammetry for mapping and 3D modelling of urban archaeological landscapes, focusing on the Byzantine-era Didymoteicho Fortress in northern Greece. High-resolution aerial imagery was captured and processed into an orthophoto mosaic and a detailed 3D model of the site’s monuments and their urban surroundings. The UAV-based survey provided comprehensive, up-to-date spatial data that traditional ground methods could not easily achieve in dense urban settings. The results illustrate how UAV mapping can document complex heritage structures, detect risks (such as structural deterioration or encroachment by development), and inform preservation efforts. The discussion situates these findings within global heritage management practices, highlighting UAV technology as a cost-effective, accurate, and non-invasive tool for safeguarding cultural heritage in urban areas. The suggested methodology enhances heritage documentation and risk assessment, demonstrating strong potential for policy integration and proactive conservation planning in historic cities.

This study provides a comprehensive evaluation of naturally occurring radionuclides—radium-226 (²²⁶Ra), thorium-232 (²³²Th), and potassium-40 (⁴⁰K)—in groundwater systems across the Nile Valley regions of Upper Egypt, based on the analysis of 85 groundwater wells. Measured mean activity concentrations were 0.74 ± 0.3 Bq/L for ²²⁶Ra, 0.24 ± 0.1 Bq/L for ²³²Th, and 13 ± 4 Bq/L for ⁴⁰K, with ²²⁶Ra displaying low correlations with salinity indicators including chloride (Cl⁻), sodium (Na⁺), electrical conductivity (EC), and total dissolved solids (TDS). Notably, approximately 30% of sampled wells exceeded the World Health Organization (WHO) guidance level of 1 Bq/L for ²²⁶Ra, primarily in central and eastern zones influenced by elevated salinity and evaporite dissolution processes. Geospatial mapping combined with multivariate statistical analysis identified four principal components accounting for over 85% of total data variability, demonstrating that depth-dependent processes, including prolonged water–rock interaction and redox evolution, are the primary controls on ²²⁶Ra mobilization, with salinity-driven ion exchange as a secondary factor. Minor anthropogenic influences, potentially linked to agricultural activities in shallow aquifers, were also detected. Radiological risk assessment confirmed that calculated annual effective doses remain well within international safety limits (<1 mSv/year), although infants and children demonstrated relatively higher exposure levels due to increased water intake per unit body weight. Lifetime cancer risk estimates via ingestion pathways yielded values below 1 × 10⁻⁴, aligning with global health organization benchmarks and reinforcing the general safety of groundwater use in the region. The study highlights potential risks posed by saline groundwater to ancient monuments and archaeological sites, as the cycles of salt forming and breaking down might speed up damage to buildings made of limestone and sandstone. These findings establish a robust scientific foundation for future groundwater quality management and cultural heritage conservation efforts in the Nile Valley region of southern Egypt. Full article

This study examines the impact of recent climatic trends on the preservation of submerged wooden structures at the Gran Carro archaeological site in Lake Bolsena, Italy. Climatic data from the Bolsena Meteorological Station were analysed alongside in situ water quality measurements collected near the archaeological remains at a depth of 4 m. The key parameters included water temperature (Tw), redox potential (Eh), dissolved oxygen (DO), and total dissolved solids (TDS). Trend analyses using the Mann–Kendall test and Sen’s slope revealed significant increases in air and water temperatures, which were strongly correlated. Although precipitation exhibited an upward trend, its negative correlation with temperature suggests greater variability rather than a stable water supply. Despite increased rainfall, lake levels showed a significant decline, likely due to intensified evaporation and water extraction for irrigation. UAV surveys confirmed recent lowering of the lake’s water surface during drought periods. Among the limnological parameters, dissolved oxygen saturation declined significantly, while redox potential increased, indicating shifts toward more anaerobic conditions. These environmental changes could promote the activity of erosive bacteria that degrade submerged wood. Conversely, increased evaporation might also enhance oxygen penetration at depth, potentially activating decay agents such as soft rot fungi and wood-boring bacteria. Overall, the findings suggest that ongoing climatic changes are adversely affecting the preservation of submerged wooden structures, highlighting the need for adaptive management strategies to protect both the lake ecosystem and its archaeological heritage.
