Erzurum Yakutiye Medresesi Yapı Malzemeleri, Bozulmalar ve Koruma Problemleri

Yakutiye Medresah in Erzurum was built in 1310 at the period of Ilhanian Sultan Olcayto. One of the well preserved example of the Medresah in Anatolia has the typical eyvan and close courtyarded structure. It has the very distinguished place in the Mid-Age Turkish Art due to its well organised plan, figurative stone ornamentation and reliefs of portal and tiled brick minaret properties. Because of these reasons it has to be precisely preserved.Medresah building is now using as a museum but structurally there are profound conservational problems. In addition, especially air pollution and climatic effects cause deterioration on original surfaces of the materials.Before the conservational and restorational practises, understanding the problems and analysing the properties of materials is very important to find reliable and long-lasting methods. For this reason the research and material analyses were established in 2005 under the project of “Erzurum Yakutiye Medresah Graphic Documentation, Restoration Project”. At the end of the field study / survey and loboratorial studies; - Historical applications, past restorations, interventions or interferances were documented, - Structural materials of the building were analysed and characterized by using some archaeometric methods, - The types of deterioration problems of the materials and their reasons were determined and some solutions were proposed. In this way, the Erzurum Yakutiye Medresah Constructive Material Research Project was realised by the interdisciplinar group from different fields.
