#964 Davit Gareje Monastery, Georgia

Davit Gareje is a monastery in Georgia quite near to the Azeri border founded in the 6th Century by St. David Garejeli, one of the 13 Assyrian monks and remains an important religious site to this day. It is hidden away in rolling grass-covered hills and its prescence and complexity remain hidden until inside the complex walls. Reminiscent of Capadocia in Turkey, it is carved into a sloping hillside, with rooms cut directly from the rock. It was fortified from invaders with a strong wall and other buildings added to the complex apart from the cave dwellings, and continues up the hillside of Mount Gareje to the highest point.
