The Tomb of Sinan Dede, located in Gümüşgün Village of Gönen District of Isparta, is one of the few examples that carries the Alevi-Bektashi Culture to the present day, spatially and structurally, in the mentioned geography. Inside the tomb, there is a sarcophagus belonging to the person known as "Seyyid Sinan Baba", one of the Anatolian saints and Khorasan soldiers, who is both a soldier who Turkified and Islamized Anatolia and a great saint. Since there is no foundation charter or inscription, the exact date of construction of the building is not known, but according to information obtained from various sources, it is thought that the building was built after the establishment of the Ottoman Empire. The tomb, which hosts the Alevi-Bektashi culture and belief traditions, was evaluated as a cultural heritage in this study and the data obtained from these projects were prepared by preparing survey, restitution and restoration projects that included conservation and intervention decisions that would ensure the sociocultural and spatial continuity of the structure. Based on this idea, first, the spatial and structural problems of the building were mentioned, and then the intervention decisions were given to eliminate these problems and to ensure that the building could continue its current function as close to the original space. It is aimed to transfer the Sinan Dede Tomb, which is one of the few Alevi-Bektashi places still actively used in its geography and therefore carries a symbolic value, to future generations with its original function and structural elements, and to contribute to the literature on the preservation of cultural heritage.
