The history of building monasteries on top of perilous cliffs near Meteora occurred between the 14th and 15th centuries. Even prior to this, in the 11th century, religious communities had established hermitages at the foot of these cliffs. In the 14th century, the titular emperor of Serbs and Greeks, John Uroš, became a monk and moved to Meteora; he endowed, rebuilt and established monasteries here.
