World's Wildest Houses VII

Kalambaka, Greece

No Photoshop trickery here! These are real, inhabited buildings built right up to the edge of a nearly 1,000 foot cliff drop. The strange Greek mountain formations of the Meteora (Greek for "in midair") have been home to monks since at least the 11th century. Numerous monasteries cropped up throughout the rocks over the subsequent centuries, six of which are still in use and open to the public—assuming, of course, that the public has the fortitude to make the climb.
