The Domus Civita, Civita Di Bagnoregio, Italy

History
It was founded by Etruscans over twenty-five hundred years ago but has seen its population dwindle to just fifteen residents over the course of the 20th century. Cività was the birthplace of Saint Bonaventure, who died in 1274. The location of his boyhood house has long since fallen off the edge of the cliff. By the 16th century, Civita was beginning to decline, becoming eclipsed by its former suburb Bagnoregio.
At the end of the 17th century, the bishop and the municipal government were forced to move to Bagnoregio due to a major earthquake, accelerating the old town's decline. At that time, the area was part of the Papal States. In the 19th century, Civita's location was turning into an island and the pace of the erosion quickened as the layer of clay below the stone was reached in the area where today's bridge is located. Bagnoregio continues as a small but prosperous town, while Civita became known as il paese che muore (in Italian: "the dying town"). Civita has only recently been experiencing a tourist revival.
