The Holy Saviour in Chora was a Byzantine church decorated with 14th-century frescoes of the Last Judgement that remain treasured in Christendom. It was originally converted into the Kariye Mosque half a century after the 1453 conquest of Constantinople by the Ottoman Turks. It became the Kariye Museum after World War II as Turkey pushed ahead with the creation of a more secular new republic out of the ashes of the Ottoman Empire.
