Located in the Sivrihisar district of Eskişehir, this historic timber-post mosque had undergone numerous interventions over time. The project commenced with a high-precision digital survey, using 3D laser scanning to accurately model the structure and document its complex history of alterations. Following this, the restitution phase was developed based on detailed historical research and comparative studies of analogous timber-post mosques, aiming to identify its original character. The final restoration project was designed with a modern approach that respects the building's historical integrity and cultural value. The complete set of survey, restitution, and restoration projects has been approved by the relevant Regional Conservation board.
