Monastery Roussanou, Meteora, Greece.
All of the monasteries are perched on high cliffs and now accessible by staircases cut into the rock formations. They were created to serve monks and nuns following the teachings of the Eastern Orthodox Church. Much of the architecture of these buildings is Athonite in origin. Of the six intact monasteries, the Holy Monastery of St. Stephen and Monastery Roussanou are inhabited by nuns.
