Hirami Ahmed Pasha Mosque, Byzantine mosque in Çarşamba, Istanbul, Turkey.
The brick structure features a cross-in-square plan with a central dome supported by four columns and illuminated by triple windows.
Originally constructed in the 12th century as an Eastern Orthodox church dedicated to Saint John the Baptist before its conversion to a mosque between 1587 and 1598.
The building represents a transition between Byzantine and Ottoman religious architecture, preserving elements from both traditions in its structural design.
The mosque stands on Koltutçu Sokak, 400 meters south of Pammakaristos Church, and reopened for Islamic worship in 1961 after restoration.
This structure holds the distinction of being the smallest surviving Byzantine church in Constantinople, measuring only 15 meters in length including the narthex.
