The Chora Church or Kariye Mosque (Turkish: Kariye Camii) was a Byzantine church, now converted to a mosque (for the second time), in the Edirnekapı neighborhood of Fatih district, Istanbul, Turkey. It is famous for its outstanding Late Byzantine mosaics and frescos. In the 16th century, during the Ottoman era, it was converted into a mosque; it became a museum in 1945, and was turned back into a mosque in 2020 by President Recep Tayyip Erdoğan. The interior is covered with some of the finest surviving Byzantine Christian mosaics and frescoes, which were protected and left in plain sight during Muslim worship throughout much of the Ottoman era. They were restored after the building was secularized and turned into a museum. The church is located in the western Fatih district of Istanbul. It stands on sedimentary layers and anthropogenic infills on a slope descending towards the north. It is oriented east-west, as are typical Byzantine churches throughout the city.
