Analysis of Cultural Heritage by Non-Destructive Methods: The Case of Sivas Congress Museum

Analysis of cultural heritage by non-destructive testing methods allows conducting an examination of the building while preserving its authenticity and integrity, as well as its historical and artistic values. As the material of this study, the Sivas Congress Museum, which witnessed a very important event in the history of the country, was discussed. The aim of the study is to determine the stone type, deterioration, hardness, and strength of the building and thus generate an idea about the quality of architectural practices in the 19th century. In addition, it aims to create a scientific basis for conservation measures and restoration works to be carried out in the following years and to determine whether there is any difference between the stone material used in the main building and the stone of the building annexed later on. At the end of the study, it was concluded that the poor economic conditions of the country have affected the quality of the building material, the stones – soft and low-strength limestone – have been exposed to atmospheric pollution and deteriorated. In addition, although one of the stones that had undergone black crusting was cleaned, it was found that mechanical cleaning was insufficient to eliminate the pollution.
