No Photoshop trickery here! These are real, inhabited buildings built right up to the edge of a nearly foot cliff drop. The strange Greek mountain formations of the Meteora (Greek for "in midair") have been home to monks since at least the century.
Monastery of Holy Trinity, Meteora may be one of my favorite spots in Greece. They used to pull the monks up in baskets. Do you know how they knew when to change the rope? When it broke silly! Glad I wasn't that monk.
