The Chora Museum (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.[1] The church is situated in the western, Edirnekapı district of Istanbul. In the 16th century, the church was converted into a mosque by the Ottoman rulers, and it became a secularised museum in 1948. The interior of the building is covered with fine mosaics and frescoes.
