Sümela Monastery
Maçka, Turkey · built 386
Sumela Monastery (Moní Panagías Soumelá, Turkish: Sümela Manastırı) is a museum and former Greek Orthodox monastery in the Pontic Mountains, in the Maçka district of Trabzon province, Turkey. Dating back to ancient times, it was in use until the Greco-Turkish population exchange in 1923. Nestled in a steep cliff at an elevation of about 1,200 metres (3, 900 ft) facing the Altındere valley, it is a site of great historical and cultural significance, as well as a major tourist attraction within Altındere National Park. It was closed to the public for safety reasons in 2015, due to an increase in rock falls, but reopened in 2019.
