Şeyh Süleyman Mosque (full name in Turkish: Şeyh Süleyman Mescidi, where mescit is the Turkish word for a small mosque) is a mosque in Istanbul converted from a former Byzantine building which was part of the Eastern Orthodox Pantokrator Monastery. Its usage during the Byzantine era is unclear. The small building is a minor example of architecture of the Byzantine middle period in Constantinople.
The structure is located in Zeyrek Sokak, in the district of Fatih, in the neighborhood of Zeyrek, about 120 meters southwest of the former Pantokrator Church, now part of the Mosque of Zeyrek.
Nothing is known about the history of this small octagonal building before 1453. Almost certainly it was part of the great Monastery of Christ Pantokrator, erected between 1118 and 1124 by Byzantine Empress Irene Komnene. According to some scholars it could have been a burial place, while others think that it was the library of the monastery.
