The Grand Monastery of Saint Lukas was built in the west of mountain Elikonas, beneath the Acropolis of ancient Stirida, near the village Stiri at Viotia. It is one of the most significant monuments of Byzantine art, mainly because of its mosaic, and since 1990 it has been included in the world heritage of monuments of UNESCO, together with monasteries of Nea Moni of Chios and Dafni in Athens. The monastery, which is dedicated to the thaumaturgical Saint Lukas together with the two churches (the temple of Panagia (Virgin Mary) and the Catholicon) the Kripti (crypt), the belfry, the cells and other buildings, acquired great fame in a very small period of time because its kind of art is considered a model for the byzantine monuments of 11th century throughout Greece.
