Ancyra, St. Clement Church

The Church of Saint Clement is located in the Altındağ district of Ankara. It was built in the 4th century and dedicated to Saint Clement, the bishop of the city of Ancyra at that time. The only remaining parts of the building, which was converted into a mosque during the Ottoman period but was completely abandoned after it burned down during the Ankara Fire in 1916, are one wall and a marble block with a Latin cross. The horizontal arms of the cross have been removed.  A few saved column capitals and window frames are exhibited in the Roman Bath Open Air Museum.
