Fenari Isa Mosque, Byzantine mosque in Fatih, Turkey
Fenari Isa Mosque is a house of prayer in Istanbul's Fatih district that incorporates two former Byzantine churches into one structure. The building features domes, distinctive brick patterns, and a minaret integrated into its complex layout.
The building started as a convent dedicated to the Virgin in 908 and was converted into a mosque after Constantinople fell to Ottoman forces in 1453. This transformation marked a turning point in Istanbul's religious history.
The mosque embodies the transition between Byzantine and Islamic worlds through its mixed design elements visible throughout the building. Walking inside, one notices how Christian and Muslim features coexist within the same structure.
The mosque sits on Adnan Menderes Boulevard and welcomes visitors during prayer times. It is helpful to check opening hours ahead of time and dress appropriately if planning to enter the interior.
The site contains remains of a shrine dating to the sixth century and ancient Roman tombstones built into the northern church section. These fragments reveal how multiple historical periods are layered within the same location.
