Balaban Aga Mosque, Byzantine mosque in Fatih district, Istanbul, Turkey
The circular structure measured 11.2 meters in diameter and contained a hexagonal interior layout with niches along each wall section.
Built in the fifth or sixth century as a Byzantine building, the structure was converted into a mosque by Balaban Aga in 1483.
The building changed from its original function to serve as a mausoleum during the Palaiologan period before becoming a Muslim place of worship.
The mosque stood until 1930 when authorities demolished it for the construction of Harikzedeler Street in the Laleli neighborhood.
Archaeological excavations revealed an underground ossuary containing numerous bones, indicating the structure's early use for multiple burials.
