    Archaeological sites have to be investigated and conserved as a whole to have a better knowledge of our past. In this study, Aigai Bouleuterion in Manisa was investigated to evaluate the stone weathering and conservation problems of an excavated archaeological monument. It is also aimed to analyze the weathering process of stone material while buried and the contribution of this process to the deterioration after the excavation. For this purpose, the building was documented by photographs and drawings and several laboratory studies were carried out on both the soil and stone samples collected from the excavated parts of the building. Samples were investigated with by using XRD, SEM-EDX, TGA and FT-IR and chemical analyses. Andesite, used as a building material of the bouleuterion and the soils are both composed of the minerals of microline, orthoclase, sanidine, albite, andesine, labradorite, anorthite, muscovite, cristoballite, tridymite, quartz, kyanite, mullite and orthoferrosilite. Less amounts of organic materials, carbonate and soluble salt contents were found in the samples. The clay minerals found in the samples are halloysite, illite, kaolinite, montmorrillonite and saponite.The penetration of clay minerals to the stone structure, forming a weathering zone with the presence of clay in the cracks was determined with SEM analysis. The weathering zones of the stones range between 1 cm and 2.4 cm from the exterior surface. When the average seasonal values for the environment are examined, the weathering effect of the clays after excavation of stones generally occurs in winter months due to low temperature and high humidity values.

    Documentation of the Lower Bath in Metropolis, Torbalı, Izmir for the Assessment of Heritage Characteristics
    (Izmir Institute of Technology, 2013) Büyükkılıç, Suna; Hamamcıoğlu Turan, Mine; Turan, Mine; 02.01. Department of Conservation and Restoration of Cultural Heritage; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    The study evaluates the excavation results of the Lower Bath and Palaestra in the archaeological site of Metropolis, Torbalı, İzmir with an eye on its original qualities and alterations. In fact, the understanding of the alterations will enable one to take conscious decisions for the preservation of the bath ruins. First, the existing scaled drawings of the Bath ruins were gathered and evaluated. Then, the historical background of the Roman Bath buildings was investigated. Rectified image mosaics based on photogrammetric survey are combined with plan, sections and elevations based on tachometric survey. In addition, a 3D model of the present state of the building was produced based on photogrammetric and tachometric survey. The 2D representations were used for mapping the original elements and the altered ones. The obtained data is supported with historical research and comparative study of similar buildings. The end results are presented in large appended tables. In turn, the heritage characteristics of the Lower Bath ("Aşağı Hamam" or "Han Yıkığı) in Metropolis, Yeniköy, Torbalı, İzmir is documented in detail. The Lower Bath has an asymmetrical plan organisation. It is middle in scale (812 m2). It is a typical example of the Roman Baths dated to between 2nd and 4th century. Its original features were sustained onwards. However perception of its third dimension has been demolished. It is important to plan a documentation study systematically as parallel to the excavation studies and to develop conservation decisions.

    Examination of Deterioration Problems of Andesite Used in Aigai Agora
    (Izmir Institute of Technology, 2009) Mürtezaoğlu, Fulya; Böke, Hasan; Böke, Hasan; 02.01. Department of Conservation and Restoration of Cultural Heritage; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    The archaeological sites should be conserved as being the documents of ancient civilizations as a part of the built cultural heritage. In this study, the deterioration problems of stone used in the construction of the agora building in the archaeological site of Aigai (Manisa/Turkey) was investigated for the aim of its conservation. For this purpose, the building was documented by photographs and drawings. The stone deteriorations were documented on the drawings and samples were collected from the deteriorated and sound parts of stones. Basic physical properties, mineralogical, chemical and microstructural characteristics of the stone samples were determined to define the causes of deteriorations. X-Ray diffraction, scanning electron microscope, polarized microscope, infrared spectroscopy and thermogravimetric analyzer were used in the analysis. The stone used in the building is andesite which is mainly composed of andesine, albite high, anorthite, kyanite, labradorite, muscovite, microline, mullite, orthoclase, orthoferrosilite, quartz, sanidine and tridymite minerals. The density and porosity values of sound andesite are 2.4 g/cm3 and 8 % by volume respectively. On the weathered parts of the stone, the porosity increases with degree of weathering. The depth of the weathered zone from the surface to the inner parts which was determined by SEM analysis is about 1.7 cm. On the weathered parts of stone, clay minerals and iron oxides were determined as weathering products of andesite. The existence of clays on the exterior and the interior parts of the andesite accelerates weathering by their swelling.shrinkage properties and provide suitable conditions for the biological growth. Main weathering forms observed on the stone surfaces are detachment, deposits and loss of stone materials. The progress of weathering forms depends mainly on the difference in temperature and humidity between night and day at the site. Condensation and frost occurs mostly in winter months with increasing relative humidity and decreasing temperature. Humid and rainy conditions of winter months promote the weathering of the stone.

    Refunctioning Of Old Tanneries İn Kuşadası, Aydın
    (Izmir Institute of Technology, 2006) Teket, Zeynep Gülden; Hamamcıoğlu Turan, Mine; Turan, Mine; 02.01. Department of Conservation and Restoration of Cultural Heritage; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    This study aims to survey, analyse and evaluate the old tannery site in Kuadası, Aydın; and to propose a refunctioning scheme for the continuation of its survival. An application project for the conservation of this site has been developed by Göç-Tur Firm, which has rented the site from the Ministry of Culture and Tourism for 49 years.This thesis questions Göç-Tur.s project and develops an academic approach for the conservation problem. It claims that determination of an appropriate function for the site should be based on evaluations at tannery unit and site scales. Detailed analysis is a prerequisite for understanding of values and problems. The refunctioning scheme should consider urban requirements, reuse preferences, theoretical scope and structural necessities.The built cultural heritage in Kuadası has been continuously damaged as a result of mass tourism and the absence of forward planning. Within this context, the old tannery site is a significant potential for Kuadası as it still preserves the modest design character based on human scale and the original solid-void organization with minimum alterations. Moreover, the traditional leather production process documented via these tanneries is itself a value. When refunctioning decisions are determined mostly with the employer preferences rather than detailed analysis and evaluation phases, these decisions may be incompatible with the case potential. In turn, the appropriate function for the tannery site has been clarified after deciphering its urban and documentary values; and also spatial and structural problems within the frame of contemporary theory of conservation. Consequently, refunctioning of the discussed tannery site as a commercial district with the association of leather goods has been achieved.
