This site is located in the Thessaly District in north-central Greece and has a core protected area of 3.75 km2. It is a remote group of sandstone peaks with almost no way to pass through. Monks have lived in seclusion on these pinnacles since the eleventh century. During the restoration of the ideal of seclusion in the fifteenth century, the monks built 24 monasteries in the face of tremendous difficulties. The murals that were painted in the sixteenth century are representatives of the major stages of post-Byzantine painting.
