The Church-Mosque of Vefa is a historic building in Istanbul’s Vefa quarter that preserves elements of a medieval Byzantine church alongside later Ottoman-period mosque adaptations. It is an example of a religious building reused and adapted across cultural transitions in the city.

Originally built as a Byzantine church, the building was converted to a mosque during the Ottoman period and has since been the subject of conservation and study. Its layered fabric reflects the city’s long history of changing religious and civic uses.
Situated in the historic Vefa neighbourhood on the European side of Istanbul, the building is part of a tightly built district of streets and is accessible from central Istanbul.
