The small building is a minor example of architecture of the Byzantine middle period in Constantinople.

Almost certainly it was part of the great Monastery of Christ Pantokrator, erected between 1118 and 1124 by Byzantine Empress Irene Komnene.

[1] Shortly after the Fall of Constantinople in 1453, under Mehmed II, the building was converted into a mosque by Şeyh Süleyman Halîfe (?–1491).

[4] After the great fire of 1756 the building was restored during the reign of Sultan Mustafa III (r. 1757-74) by Kazgan Asan Aĝa, and assigned to the nearby medrese.

[4][5] The building has a square plan and is topped by a low octagonal dome with pendentives.
