The Church of the Holy Saviour in Chora (Turkish Kariye Müzesi, Kariye Camii, or Kariye Kilisesi — the Chora Museum, Mosque or Church) is considered to be one of the most beautiful examples of a Byzantine church. The church is situated in Istanbul, in the Edirnekapı neighborhood, which lies in the western part of the municipality of Fatih. In the 16th century, the church was converted into a mosque by the Ottoman rulers, and it became a secular museum in 1948. The interior of the building is covered with fine Christian mosaics and frescos. [Wikapedia]
