Civita di Bagnoregio
Hotel Tuscania Panoramico
Visiting this town is a must. "... suspended in the middle of a sea of crete …" in the words of Bonaventura Tecchi, it can only be reached on foot by a long high bridge spanning the countryside around it.
Nowadys ancient Civita di Bagnoregio has very few inhabitants.
It's threatened by small but continuous landslides that are gradually eroding the tuff spur on which it stands, it's called the dying town.
