At the end of the 17th century, the bishop and the municipal government were forced to move to Bagnoregio because of a major earthquake that accelerated 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 situated. Bagnoregio continues as a small but prosperous town, while Civita became known in Italian as La città che muore ("The Dying Town"). Civita has only recently been experiencing a tourist revival.
