Diyarbakir province comprises characteristic examples of a geographical region that carries the traces of many civilizations from prehistoric to modern times. The remains and artifacts of civilizations reigned in Diyarbakir can be found all around the city. The Diyarbakir City Walls are one of the unique remains that surround throughout the city. Diyarbakir Fortress, as an important structural design of common mankind product, has saved its importance till the XXI. Century. The fortress is located on a basalt plateau which spreads at a 70 m altitude of the western side of the Tigris River to Karacadağ and it consists of two parts, namely interior and exterior fortresses. The interior fortress was constructed by Hurrian on 3000 B.C. The Diyarbakir City Walls consist of 82 towers; the height of walls, partly reach to 8-22 m and thickness of walls to 0,8-5.25 m, extended almost 6 km around the city. As a historical and cultural property, the Diyarbakir City Walls were constructed by using natural stones (basalt). Although the City Walls were subjected to numerous past interventions and scientific studies, the behavior of the material used in the structure, origin and deterioration mechanism of the stones, unfortunately, have not been comprehensively studied. The interventions carried out without identifying the long-term performance of materials in their natural conditions, cause new and irreversible damages on the structure. This undesirable situation can be observed on the Diyarbakir City Walls as well. Hence, some structural and deterioration problems have emerged as a result of improper conservation interventions. In this study, the physical properties such as effective porosity, unit weight, water absorption, saturation coefficient of basalts used in the City Walls and the weathering forms such as detachments, discoloring, scaling, fissuring, efflorescence, microbiological colonization and material loss developed in the City Walls were investigated.

Palaeoenvironment and human interaction during the last 4k years in the dried lake sediments (amik lake, southern turkey): evidences of lake level changes El Ouahabi, Meriam; Hubert-ferrari, Aurelia; Auwera, Vander; Avşar, Ulaş; Karabacak, Volkan (2019-02-01) The Amik Basin in the Eastern Mediterranean region has been continuously occupied since 6000-7000 BC. The landscape has sustained with highly variable anthropic pressure culminating during the Late Roman Period when the Antioch city reached its golden age. The basin also sustained a high seismic activity (M≥7) as it is a releasing step-over along the Dead Sea Fault. The study focuses on the sedimentary record of the Amik Lake occupying the central part of the Basin. Our objective is to constrain major paleo...
Integrated Management of Archaeological Heritage: Mediterranean Coasts of Turkey Nayci, Nida; Şahin Güçhan, Neriman (2007-11-17) Mediterranean coastal areas possess great amount of historic and archaeological assets joined up with ecological and natural values. Many of these fragile environments were originally constructed on the dry-lands, which have been transformed into different environmental context with the evolution of coastal areas Over centuries and millennia. Today, increased population and poorly planned coastal activities are conflicting with the conservation principles of these fragile environments.
Romanization of urban spaces in Ephesus Topal, Hidayet Volkan; Güven, Suna Naziyet; Department of History of Architecture (2020-9) Expansion of the Roman sphere of influence over various societies and heterogeneous cultures prompted a unique acculturation in the provinces that is referred to as Romanization. The imperial cult, in general, is considered to be both an indicator of this cultural change and an agent that took an effective role in the process of acculturation. The imperial cult in the provincial context of Asia provides a remarkable case to grasp the acculturation under Roman rule, as a catalyst of defining individuals’ and...
Integrated Management Principles for Coastal Cultural Landscape Areas of Turkey NAYCI, NİDA; Şahin Güçhan, Neriman (2011-10-29) Cultural landscape contexts generated by natural,, historical and rural environments are significant aspects of Mediterranean coastal areas, which possess accumulated information related to past experiences and meanings showing relationship of man-kind with coastal environments. Introduction of 'cultural landscape conservation' as a new topic into international mediums has become important especially after 1980s as a result of the increase in the awareness of "sustainability" and "sustainable development". ...
Nomadic Cultures in the Mega-Structure of the Eurasian World (Book Review) Pamir Dietrich, Ayşe (2018-07-01) Nomadic Cultures in the Mega-Structure of the Eurasian World by Evgenij N. Chernykh is a comprehensive work that examines the history of Eurasian nomadic peoples and their influence on world history and culture. Translated from the original Russian, it consists of an introduction, forty chapters organized into five parts, five appendixes, two extensive bibliographies – one for sources written before 1500, and one for modern sources - and an index. The book begins with “Part I: The Steppe Belt in the Mega-S...
