Article Citation - Scopus: 1Characteristics and Production Technologies of Byzantine Building Bricks From the Anaia Church in Western Anatolia(Springer, 2023) Çam, Elif; Uğurlu Sağın, ElifFired bricks were valued as essential building materials in the central tradition of Byzantine architecture in Constantinople (Istanbul), Anatolia, and the Balkans. In this study, Byzantine bricks from three construction periods, covering nearly nine centuries (fifth-fourteenth centuries), of Anaia Church (Kadikalesi) in Western Anatolia were investigated to determine their characteristics, raw material properties, and production technologies. The characteristics of the bricks were evaluated and compared in order to identify similarities and differences between the periods and to investigate the continuity of the tradition of brick production over centuries. Basic physical and colorimetric properties, chemical and mineralogical compositions, thermal behavior, and microstructural and mechanical properties of bricks were determined by scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (SEM-EDS), Fourier-transform infrared spectrometry (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and mechanical tests. The results indicated that all the bricks in the Anaia Church were brown-beige colored, highly porous, low-density materials with low mechanical strength. They were produced from Ca-rich clays, probably obtained from two different sources used during all construction periods. The mineralogical composition and thermal properties revealed that the bricks from the first and second periods were fired at between 800 and 900 & DEG;C and the bricks from the third period were fired at < 850 & DEG;C. Greater calcium content and firing temperatures were found to reduce the total porosity and the number of small pores (< 10 & mu;m) and increase the mechanical strength of the bricks. The results of the study revealed no significant differences in the production of bricks, including raw material sources and kiln conditions, for the different construction periods of the church.Article Citation - WoS: 1On-Site Measurements of Temperature and Humidity Conditions for the Comparison of Urban and Rural Sub-Spaces of Traditional Settlements: Historical City of Mugla, Turkey(Taylor & Francis, 2023) Timur, Barış Ali; Başaran, Tahsin; İpekoğlu, BaşakOne of the significant processes that ensures realistic determination of the energy needs of historical buildings is case-specific definition of their local microclimatic conditions. Accordingly, the aim of this study is to determine differences for the parameters of temperature and humidity in urban and rural sub-settlements of the historical city, Mugla/Turkey. Study method consists of on-site measurements of these variables in sub-settlements for comparisons. As a result, it was identified urban zone shows heat island characteristics with warmer, drier, and more stable conditions; while rural sub-settlement remains cooler, more humid, and more erratic. In parallel, calculated extents of these differences demonstrate the significance and necessity of on-site measurements and consequential microclimatic zoning of historical cities as conservation/planning tools for responding to the thermal needs of architectural heritage. A key application of these processes would be the establishment of local databases of case-specific weather data to be used in thermal simulation assessments.Article Citation - WoS: 9Citation - Scopus: 9The Tourism Potential of Post-Mining Heritage Sites: The Cyprus Mining Cooperation in Lefka, Cyprus(Springer, 2022) Oktay Vehbi, Beser; Mısırlısoy, Damla; Günçe, Kağan; Yüceer, HülyaThe mining sites have geo-scientific, industrial, cultural, aesthetic, economic, historic and anthropological potentials for the development of tourism. Lefka with an ancient history of mining and having rich geodiversity as well as various historical and cultural monuments, archaeological sites along with poor economic conditions can develop tourism with mining tourism goals. The study aims to examine the tourism potential of post-mining heritage sites as part of a strategic approach and tool for planning that encourages local development through the case of the Cyprus Mining Cooperation (CMC), a derelict copper mining field in Lefka, North Cyprus. Established during the British administration of the island, CMC covers a large area that comprises of mine fields, processing units, laboratories, workers houses and other related public buildings serving the whole complex, which were left derelict about sixty years ago. The study presents the values—scientific, aesthetic, economic, historical and cultural—associated with the site and its components, the criteria for their conservation and reuse opportunities for tourism purposes. Conservation strategies are suggested within the framework of ‘mining tourism’ to present the heritage significance of the site.Article Citation - WoS: 6Citation - Scopus: 6Valuing Groundwater Heritage: the Historic Wells of Kadıovacık(Springer, 2021) Yüceer, Hülya; Baba, Alper; Özcan Gönülal, Yasemin; Uştuk, Ozan; Gerçek, Deniz; Güler, Selen; Uzelli, TaygunThe consideration of the subject of water resources, seen as a part of cultural heritage, generally includes water-related architectural structures such as bridges, aqueducts, and cisterns. Groundwater resources and related structures, however, receive little attention as heritage assets, and they are mostly forgotten together with the valuable information they hold. In this sense, this study aims to provide an accurate assessment of groundwater heritage and to suggest proposals for conservation through the case of the historic wells of Kadıovacık village in the Urla district of İzmir. Although the region where the village is located is rich in groundwater resources, the residents have suffered from drought for ages due to the specific geological characteristics of the Kadıovacık polje. The limited amount of water resources in Kadıovacık village have karstic characteristics and have shaped the life and topography of the region. To access and harvest this limited groundwater, a group of wells had been constructed on the ridge of the hill. These wells have been idle since 1980s with the supply of city main water. In line with the aim, a comprehensive heritage valuation by an interdisciplinary group of experts is essential to reveal the significance of the relatively humble wells. Accordingly, a multi-method system is used, including historical, social, cultural, architectural, geological, hydrogeological, and environmental aspects. The results show that although the wells are generally considered to be less important as heritage assets in terms of their physical features, an in-depth evaluation demonstrates their high significance for the village community.Article Citation - WoS: 5Citation - Scopus: 6Revisiting the Conditions of Authenticity for Built Heritage in Areas of Conflict(Mdpi, 2021) Saifi, Yara; Yüceer, Hulya; Hurol, YoncaThis article examines the application of conditions of authenticity within the context of built heritage management in areas of political conflict, where heritage management can be seen as a political act rather than a means of protection. It focuses on values attributed to built heritage that can be targeted or reinvented by the dominant power in areas of conflict with minorities being powerless to intervene. The argument is built around the Agios Synesios Church in North Cyprus, which continued to be used by the Greek Cypriot minority following the island division in 1974. Although their way of life has been compromised, they have embraced forced change through using the church to maintain their ritual and religious practices; by doing so, they negotiate their values towards their heritage. In this case, the study shows that the conditions of authenticity are difficult to meet, given the means through which heritage management can be manipulated. Accordingly, the article aims to contribute to general discussions on the vagueness and enigmatic conditions of authenticity in areas of conflict. Different buildings in areas of conflict around the world suffer because of the political nature of heritage management, which makes the criteria of authenticity unviable.Article Citation - WoS: 1Citation - Scopus: 2Consolidation of a Bath Ruin in an Archaeological Site(Taylor and Francis Ltd., 2022) Durmuşlar, Feyza; Turan, Mine; Yücetürk, Kutay; Aktaş, EnginThe study has focused on consolidation of a historical bath ruin in an archaeological site. Cevher Pasa Bath, which is located in Tabae archaeological site in Denizli, Turkey and dated to the 15th century, presents structural problems. The aim of the study is to propose a framework for planning consolidation of the ruins of Cevher Pasa Bath so that conservation work regarding similar masonry ruins in archaeological sites can be guided. Thus, methods of architectural restoration and civil engineering are combined in an interdisciplinary scope. Provision of temporary shoring as an emergency intervention, consolidation and presentation of the ruin within the scope of an interdisciplinary restoration project, and monitoring of the asset within the frame of a monument management plan are suggested, respectively. Structural analysis considering stress and overturning moment checks are performed. Consolidation work includes only supporting of arch remains. Some walls of the ruin are weaker than other parts. These parts need further detailed analysis, and if necessary, further consolidation and strengthening are to be carried out. The monument management plan points out the necessity of collaboration of local and central administrations, and also non-governmental organisations.Article Citation - WoS: 4Citation - Scopus: 6Impacts of Tourism-Led Constructions on Geoheritage Sites: the Case of Gilindire Cave(Springer, 2020) Aydın, Rozelin; Yüceer, HülyaGeological heritage sites are of great importance both for better understanding of the formation of the earth and for transferring its memory to future generations. People's curiosity to access this information leads to tourism activity, in which caves constitute a significant place as sources of geotouristic attractions. In the case of Turkey, caves can also be considered as the major source of tourist attractions and thus economic gain providers for local communities. Focusing on the contribution of tourism to the economy, most local authorities allow tourism activity for the caves without adequate research. This leads to the construction of buildings for the needs of visitors and the installation of walking pathways, ladders, and luminaires inside the caves, which are in most cases harmful to cave ecosystems. Located on the Mediterranean coastline of Turkey, Gilindire Cave presents such a case. Unlike other caves in Turkey, it is among three caves that were found to occur in the Cambrian limestone caves literature. Thus, any data to be detected in this environment is of scientific importance. However, service buildings constructed in the upper elevation of the cave and visitor stairs and luminaires installed in the interior constitute major threats to accessing this valuable information. In this context, the study aims to examine the caves in the scope of geotourism and tourism-led constructions through the example of Gilindire Cave. As a result, the study underpins the importance of diligent investigation of cave ecosystems prior to any tourism-led activity and principles for the service structures to be built in such geoheritage sites.Article Kent İçi Arkeolojik Alanlarda Katmanlaşmanın Analizi ve Koruma Sorunları: Foça Örneği(Türk Tarih Kurumu, 2018) Taşcı, Burcu; Akyüz Levi, EtiFoça Batı Anadolu’da Prehistorik dönemden başlayarak Arkaik, Klasik, Helenistik, Roma, Bizans, Ceneviz kolonisi ve Osmanlı dönemlerinde sürekli iskân görmüş, çok katmanlı bir yerleşimdir. Kentte arkeolojik kazı çalışmaları 20. yüzyıl başından günümüze aralıklarla devam etmektedir. Üçüncü dönem kazı çalışmaları Prof. Dr. Ömer Özyiğit başkanlığında 1989 yılından beri sürmektedir. Modern Foça kenti, tarihi yaklaşık M.Ö. 3000’lere dek uzanan antik Phokaia kentinin üstünde bir katman olarak bulunmakta ve kazı çalışmaları da kent içi arkeolojik alanlarda yoğunlaşmaktadır. Kentin tarihi katmanlaşmasında en üst tabaka olarak Osmanlı dönemi sivil mimarlık örnekleri öne çıkmaktadır. Bununla birlikte modern kent dokusunu az katlı, niteliksiz betonarme yapılar oluşturmaktadır. Kentte ilk sit kararlarının belirlendiği 1977 yılından günümüze dek sit sınırları pek çok kez değişmiş ve bu durum yeni yapılaşmanın önünü açmıştır. Özellikle turizmin ve ikincil konut yapımının artması ise kültür varlıklarına zarar vermiştir. Bu olumsuz durum kent içi arkeolojik alanlarda katmanlaşmanın zarar görmemesi için farklı yaklaşımlara gereksinim duyulduğunu göstermektedir. Kentsel arkeoloji çalışmaları bu gereksinime yanıt verecek nitelikte olup, kapsamlı tarih araştırmaları ile desteklenen kazı çalışmalarında ortaya çıkan verilerin, kentlerin koruma, planlama ve gelişim süreçlerine eklenmesini öngörmektedir.Article Citation - WoS: 11Citation - Scopus: 10Assessment of Construction Techniques and Material Usage in Izmir Rural Houses(Taylor and Francis Ltd., 2015) Tunçoku, Selim Sarp; İnceköse, Ülkü; Akış, Tonguç; Yalçın, Mehmet AliThe domestic architecture in the rural villages of ̄zmir comprises a unique built environment with their masonry wall textures, semi-open sofas, round tiled-hipped roofs, and chimneys, and represents an important part of the cultural and architectural heritage. This assessment is mainly based on field observations that focus on the architectural and structural layout of intact, damaged, and destroyed houses. During field observation and the analysis of data certain plan typologies and relationships between the geological formations of the region and choice of materials and construction techniques were observed. While load-bearing masonry and timber skeleton systems are common, extensive use of timber laces, stone, and fired or adobe brick masonry with mud mortar and timber frames infilled with masonry materials were frequently seen. Generally, round timber elements such as wall plates, laces, lintels, posts, and frames of flooring systems are used. Architectural degenerations in authentic houses, defective details and partially due to the earthquake-prone nature of the region seismicity have been evaluated. An overall approach for the preservation and sustainability of this heritage is suggested.Article Citation - WoS: 6Citation - Scopus: 9Reconstruction of Archaeological Sites: Principles Practice and Evaluation(Taylor and Francis Ltd., 2012) Yaka Çetin, Funda; İpekoğlu, Başak; Laroche, DidierThe reconstruction works at archaeological sites need to be approached with caution to prevent disturbing any surviving evidence. This study aims to develop criteria for the evaluation of reconstructions at archaeological sites. The criteria have been developed through review of current international and national conservation charters to help improve reconstruction proposals. These criteria are determined considering the remain scale and the site scale. Accuracy of the reconstruction, avoidance of physical damage, compatibility of materials, distinguishability of the interventions, availability of the interventions for future applications, and reversibility are the criteria concerning the remain scale; limits of the intervention, retainability of the original characteristics of the site, and perception of the reconstruction are the criteria concerning the site scale. These criteria are applied to the reconstruction works realized at the West Stoa of Agora, zmir, Turkey during 1930s, which had to be dismissed and reimplemented in 2000s. The recent reconstruction was applied with compatible materials; the interventions did not damage the original materials and they are distinguishable. This study of the reconstruction presents the latest architectural information, provides a basis for future studies, and is reversible. The reconstructed structure does not falsify the original characteristics, but enables increased perception of the site.
