The Sümela Monastery (Turkish: Sümela Manastırı) stands at the foot of a steep cliff facing the Altındere valley in the region of Maçka in Trabzon Province, Turkey. Lying at an altitude of approximately 1200 metres, it is a major tourist attraction of Altındere National Park. Founded in the year 386 AD during the reign of the Emperor Theodosius I (375 - 395), legend has it that two priests undertook the founding of the monastery on the site after having discovered a miraculous icon of the Virgin Mary in a cave on the mountain.
