This hillside ghost town was founded in the 8th century, and sits on a cliff that's 1,312 feet off the ground. The city emptied due to various natural disasters. In 1963, many evacuated after a landslide; in 1972 a flood made conditions even more precarious; and in 1980 an earthquake caused the town to be abandoned in its entirety.

A locked gate surrounds the city, so visitors must book a guided tour. Thanks to a miraculously unscathed statue of the Virgin Mary, the town hosts various religious festivals throughout the year. And despite the fact that the area is a ticking time bomb, the city has been used for several films, including "Passion of the Christ."
