• Archaeoseismological study of tilted foundations at Felix Romuliana, Gamzigrad, Serbia

  A study of the Gamzigrad-Romuliana palace complex, a UNESCO World Heritage Site in Serbia, reveals that severe foundation damage and structural destruction observed at the site were likely caused by natural forces rather than human activity. The research found strong correlations between foundation inclinations and natural terrain slopes, suggesting slope instability triggered by heavy rainfall or seismic activity. Historical earthquake records indicate that such events could have occurred in the 3rd century CE, with predicted seismic ground motions capable of inducing soil slumps on the alluvial fan where the palace stands. The study combines archaeoseismological analysis with geological data to propose natural causes for the observed damage, offering new insights into the resilience and vulnerabilities of ancient structures in seismically active regions.

• Romuliana-Gamzigrad. Palace and/or villa?

  Recent discussions challenge the long-standing classification of Romuliana-Gamzigrad as a palace associated with Emperor Galerius, instead suggesting it may better fit the criteria for a villa. The study critically examines the site's characteristics against established palatial indicators from the Tetrarchic period (late 3rd to early 4th century AD), identifying features that support both interpretations. By analyzing architectural elements, spatial organization, and functional aspects, the research highlights inconsistencies in the traditional 'palace' attribution while proposing a nuanced framework for distinguishing between villae and palatial structures in the Balkans during this era.

• Eine neu entdeckte villa im Umfeld des Palastes Romuliana-Gamzigrad

  A newly discovered villa in the vicinity of the Palace of Galerius at Gamzigrad-Romuliana challenges conventional distinctions between palatial and residential structures. This study compares the archaeological evidence of Romuliana's 'Palace' with that of the 'Villa extra muros' at Gamzigrad, providing a nuanced framework for differentiating these architectural forms. By analyzing spatial organization, structural features, and contextual clues, the research offers insights into the functional and symbolic roles of these sites in late Roman society. The findings contribute to ongoing debates about the nature of Romuliana's complex, shedding light on its possible dual function as both a ceremonial center and a private residence.

• Eine neue Statue des Thrakischen Reiterheros aus Gamzigrad

  A significant archaeological discovery at the UNESCO World Heritage Site Gamzigrad-Romuliana, the Palace of Galerius, has uncovered a previously unknown marble statue depicting a collapsing boar. This rare find, likely representing the Thracian hero associated with bravery and strength, provides new insights into the iconography and religious significance of the site during the Roman era. The research, published in Ancient Cult in Balkans, analyzed the statue's craftsmanship, symbolism, and contextual placement within the broader archaeological landscape of Gamzigrad-Romuliana. Such discoveries enhance our understanding of the cultural and mythological layers embedded in this historic complex.

• Review - Gerda von Bülow, Sofija Petković (Hrsg.), Gamzigrad- Studien I: Ergebnisse der deutsch-serbischen Forschungen im Umfeld des Palastes Romuliana. Römisch-Germanische Forschungen 75 (Reichert Verlag, Wiesbaden 2020)

  Gamzigrad-Romuliana, the Palace of Galerius, emerges as a significant archaeological site with new insights into its construction and function. The study presents findings from German-Serbian research that shed light on the architectural techniques and historical context of this UNESCO World Heritage Site. Key discoveries include advanced masonry methods and the integration of local materials, reflecting the engineering prowess of the Roman era. The research employs a multidisciplinary approach, combining architectural analysis with material science to reconstruct the palace's original design and purpose. This work not only enhances our understanding of late Roman architecture but also provides a deeper context for the site's preservation as a cultural heritage landmark.

• The Efficiency of Chemical Cleaning of Different Metal Artefacts from Felix Romuliana and Gradina Archaeological Sites (Serbia)

  Chemical cleaning of metal artefacts from the UNESCO World Heritage Site Gamzigrad-Romuliana and Gradina (Serbia) reveals distinct efficiencies depending on the corrosion products. EDTA-Na 2 rapidly removes lead carbonates, while citric acid excels at eliminating copper-based corrosion like malachite and cuprite. EDTA-Na 3 shows selectivity in removing silver oxides and copper compounds but is less effective on iron deposits such as goethite and magnetite. The study highlights the varying effectiveness of these solutions, their risks, and the transformation of corrosion products, offering critical insights for conservation practices.

• Sustainability of Cultural Heritage in Inland Territories

  A key insight from this study is that sustainable cultural heritage management in inland territories can effectively balance preservation with tourism development, as demonstrated by the case of two Serbian archaeological sites. The research analyzed plans for Gamzigrad-Romuliana and Caričin grad (Justiniana Prima), focusing on their alignment with principles of conservation, revitalization, and public engagement. It identified conflicts between heritage protection and tourism growth while proposing recommendations to mitigate these challenges. The study underscores the potential for inland cultural sites to contribute to both scientific and tourist value without compromising long-term sustainability.
