Turkey - Ismail Fakirullah Tomb and its Light Refraction Mechanism

Ismail Fakirullah Tomb and the other two structures associated with the Light Refraction Mechanism are located within the district of Aydınlar (Tillo), Siirt. The Tomb was built after the death of Ismail Fakirullah by a student of his, Ibrahim Hakkı, in the 18th cent. The tomb stones date from the 19th cent. It has partially lost its authenticity due to misguided restoration works carried out in 1963. Ismail Fakirullah Tomb consists of two rooms and a hallway covered by one large and two small domes and a tower. The Tomb has a square plan covered by a dome. The transition to the dome is through squinches. There are two-level windows on all façades of the structure. The windows at the lower level have straight lintel with curved arched window pediment, while the windows at the upper level have a pointed arch span. There are also pointed arched pediment windows on the drums of the dome.
