Conservation problems in stone structures found on the coast section in the example of the historical yason church

In order to transfer the historical stone structures, which constitute a large part of our cultural heritage that has survived to the present day, with their original qualities, to future generations, the handling of conservation studies on this subject in the context of "monument-specific" and "atmospheric environment in which the monument is located" contributes to the solution of conservation problems. In addition, the importance of monitoring the state of the monument at certain periods after the restoration applications has been revealed by scientific studies. "Yason Church" dated 1869, located at an elevation close to sea level, in Ordu Province, Persembe District, Çaytepe Village, Cape Yason; The 28.03. It was registered with the decision dated 1985 and numbered 816. The building is a cultural heritage with the characteristics of a first group monument and sets an example for this subject. Although the Jason Church was restored in 2004 with the approval of the Ministry of Culture and Tourism, different deformations are observed in the stone material that forms the outer shell of the building today. In this study, it is aimed to reveal the observed deformations in a cause-effect relationship. For this reason, the geographical location of the church structure and the atmospheric effects it is exposed to are examined in line with annual seasonal data. In order to determine the distribution and intensity of the deteriorations on the facades of the building, which are exposed to different atmospheric effects; The mapping technique, which is a non-destructive analysis method, is used. Determining the existing deteriorations on the monuments with the mapping technique is a work that is accepted in international conservation platforms, which constitutes a prelude to the scientific analysis of the current status of the monuments before the restoration applications. The types and distributions of the deformations revealed by visual analysis on the scaled facade surveys of the Yason Church are examined in the context of the effects of wind, sun and precipitation factors on the facades. As a result of this examination, the deteriorations on the facades are compared and suggestions are made for the preservation of the building in this direction. It is thought that the mapping technique carried out in this study will constitute a "a very important document that needs to be prepared before conservation practices" of the historical Jason Church and can prepare a discussion environment on the different analysis methods that should be done by materials science experts afterwards.
