Mardin, which is one of the rare cities where the diversity and unity of language, religion and culture is based on tolerance throughout history, supports this situation with its historical monuments. This ancient city, which was inhabited by different administrations, experienced its peak in terms of economy and stability in the 12th century during the Artuqid period. Many of the works that have reached today are the reflections of that period. Şahkulubey Cupola is one of the rare works that have survived to the present day. In this study; The analysis of the existing materials that can shed light on the restoration works related to Şahkulubey Cupola was carried out. Samples were taken from the pieces that fell to ground from the east, west, north and south facade walls, and the material properties were determined on these samples by SEM-EDS analysis. In addition, the density, unit weight, porosity-compactness, water absorption and compressive strength properties of the samples were measured. The physicalmechanical and SEM-EDS analyzes of the materials used in the construction of Şahkulubey Cupola have revealed their properties. In addition, it will be possible to apply materials compatible with the existing structure that can be used in the restoration works of Şahkulubey Cupola.
