Civita di Bagnoregio, Italy
All that remains of an old palace is the façade, the rest collapsed into the canyon from erosion of the hill Civita sits on.
At the entrance to Civita, this arch was cut by the Etruscans 2,500 years ago.
This church is on the site of an Etruscan temple, and after that a Roman temple. It has a fine campanile (bell tower), altar, and crucifix.
