The monastery of Hosios Lukas was an important center of Greek Orthodox Christianity in the Byzantine period. It is located on Mount Helikonas, in Central Greece and was founded by Hosios Lukas, known as "the steriotes." The present monastery contains the monks' cells, which are two or three stories high, and the bell tower, the Trapeza, and the two shrines with the crypt where the tomb of Hosios Lukas lies. The monastery is built on a slope, and so the monastery has five sides.
