On the northern side of the small Greek Island of Ikaria is the Osias Theoktistis Monastery. The architecture of the small monastery is a traditional church, like most of the other ones located on this beautiful island. However, the small chapel, Theoskepasti, located just next door, has the most unique architecture. Built into a cave underneath a large, flat rock, from the outside, the Theoskepasti chapel looks more akin to a mushroom house than a place of worship. It is an absolute gem to see!
