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: 2Citation - Scopus: 3The Ancient City of Anazarbos and Its Significance as a World Heritage Site(Springer, 2021) Yüceer, Hülya; Gülsen, F. Fatih; Aydın, Rozelin; Güler, SelenThe concept of world heritage constitutes an important political, cultural and economic agenda in contemporary society, even though it has been criticized for being Eurocentric. In the case of developing countries such as Turkey, inclusion in the UNESCO World Heritage List helps generate much needed income through grants and tourism activity. There are currently eighteen sites in Turkey that are on the World Heritage List, and another eighty-three on the tentative list, the majority of which have been inscribed in the last decade. However, such an acceleration of attempts to promote sites as world heritage because of their attributes can also lead to conflicts about the values of the sites, project management, community enhancement and the degree to which important related studies are carried out. The ancient city of Anazarbos is one that exemplifies such a situation. The site's history as cultural and military cross-roads in the Cilicia region, and the potential to reveal those who successively inhabited and controlled it paved the way to its inclusion in the tentative list in 2014 by meeting the outstanding universal values. In this context, this study aims to provide an accurate background of in the hope of raising its status so that further research can be carried out. The study first presents the case for the concept of world heritage and then offers a thorough assessment of the city in terms of its heritage significance. Following a discussion on the values associated with the site and the changing dynamics after its inclusion to the list, the study concludes with suggestions for its holistic conservation.
