The Domus Civita, Civita Di Bagnoregio, Italy

Civita di Bagnoregio is a town in the Province of Viterbo in Central Italy, a frazione of the comune of Bagnoregio, 2 km (about 1 mile) W from it. It is about 145 km (90 mi) north of Rome.
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.
