    This study examines the properties of the lime mortar and plaster of Isa Bey Bath, Kale Altı Bath, and Yahşi Bey Bath, the last bath buildings that preserved their authentic material structure from the Aydınoğulları Principality in Selçuk. The basic physical properties, raw material, chemical and mineralogical composition, pozzolanic and hydraulic properties of the mortars and plasters were investigated using RILEM standard test methods, SEM-EDS, XRD, and TGA. The interior walls of the baths exhibit two distinct plaster layers in different colors at the lower and upper levels. Lower-level plasters consist of plaster with natural stone aggregate and Horasan plaster, while upper-level plasters consist of plaster with natural stone aggregate and/or lime plaster. The average density and porosity values of Horasan plasters and plaster with natural stone aggregate were 1.71 - 1.48 g/cm³ and 26.83% - 30.70%, respectively. Plasters with natural stone aggregate have higher lime content and lime/aggregate ratio. The natural aggregates used in the mortars and plasters were derived from a raw material source containing minerals of volcanic origin. Brick aggregates were manufactured using low calcium clay at temperatures below 850 ºC. Mortars and plasters have hydraulic characteristics due to the pozzolanic properties of the aggregates used. Basic physical, chemical, and mineralogical compositions and hydraulic properties of mortars and plasters did not have significant differences according to the buildings. The use of raw materials and production techniques with similar properties to produce hydraulic mortars and plasters in historical bath buildings for many years indicates the continuity of local knowledge.

    Climate change is currently one of the most essential and fastest-growing threats to people and their heritage around the world. Heritage assets and sites are vulnerable to the impacts of climate change due to their age and being in constant interaction with the environment and weathering processes. In particular, historic coastal settlements are highly vulnerable to climate change effects due to their proximity to the sea, which may lead to coastal erosion, changing sea levels, abrupt changes in air temperatures, storms and floods that may damage or even lead to the disappearance of these areas. Thus, developing resilience through tailor-made conservation strategies for historic coastal settlements is crucial to transfer them to future generations. In this context, this study discusses the effects of climate change through the example of Kuşadası Citadel, a historical coastal settlement located in the Mediterranean Basin, which is expected to be highly vulnerable to climate change. The study identified the potential conservation problems that may arise from the effects of climate change on the listed and 'façade to be conserved' immovable cultural assets of the Kuşadası Citadel. Accordingly, the study has developed its method. Area-specific climate change impacts were determined, vulnerability and risk analyses were performed, and administrative, site and building-scale conservation strategies were developed. In conclusion, strategies have been developed for the Kuşadası Citadel, which is highly vulnerable to the effects of climate change, to protect it from these effects at different scales. It is an example of coastal settlement research in the context of climate change adaptation and gives guidance for local-scale conservation efforts.

    Restoration and Presentation of Byzantine Defense Structures in Cilicia
    (01. Izmir Institute of Technology, 2021) Hamamcıoğlu Turan, Mine; Kenar, Aylin; Turan, Mine; 01. Izmir Institute of Technology; 02.01. Department of Conservation and Restoration of Cultural Heritage; 02. Faculty of Architecture
    The aim of this study is to evaluate current restorations and presentations of Byzantine defense structures in terms of sustaining and enhancement of the cultural heritage values and their success in solving conservation problems. So, better management of future interventions may be possible. Case study approach was undertaken: Three castle ruins in Cilicia, Turkey were focused on: Yılan and Feke castles and Kızkalesi in Korykos. The cases are located in the present-day rural areas. They are restored recently. The study consists of literature review, site survey, documentation and analysis of geographic characteristics, historic background, morphologic characteristics, construction technique and material usage and conservation activities of the case studies, identification of the cultural heritage values and conservation problems before and after interventions at the landscape, site and building scales; and discussion of the effects of the interventions on values and problems in comparison with case studies from abroad. As a result, it was determined that interventions were either unsystematic or implemented more than necessary. There is lack of a holistic approach for interventions. While some portions were intervened, others were left in-situ without any interventions. There is a tendency for reconstruction and reintegration in general. It was seen that current interventions either sustain already accumulated cultural heritage values or they have negative impact on them. Consequently, enhancement of values is not observed. Meanwhile, some of the conservation problems were ignored.
