The most appealing and breathtaking sightseeing area of Trabzon is the Altindere National Park. 47 kms southeast of Macka, this lovely park provides a fascinating setting for the 14th century Sumela Monastery of the Virgin Mary, which is perched on the rock face 270 metres above the valley, at an altitude of 1300 meters. Within the ruins of the monastery are the remains of magnificent frescoes. It is a place of exceptional natural beauty.
It was initially constructed on the steep surface of rock, as a small church in the 4th century. In the 11th century it was expanded into a monastery with 72 cells. Ottoman princes, as regional governors of Trabzon, contributed to the upkeep of the monastery, providing material and moral support. The awe inspiring and magnificent view of the monastery, with its frescoes and holy water, attract thousands of Turkish and foreign visitors every year.
