Orvieto's cathedral gets my vote for Italy's liveliest facade. This colourful, prickly Gothic facade, divided by four pillars, has been compared to a medieval altarpiece — a gleaming mass of mosaics, stained glass, and sculpture. It's a circa 1330 class in world history, back when no one dared question "intelligent design." Things start with Creation and end with the Last Judgement. Inside, the nave feels spacious and less cluttered than those in most Italian churches. It used to be filled with statues and fancy chapels until 1877, when the people decided they wanted to "un-Baroque" their church. The nave is also an optical illusion; the architect designed it to be wider at the back and narrower at the altar, making it appear longer than it is. Windows of thin sliced alabaster bathe the interior in a soft light. The cathedral's highlight is the Chapel of San Brizio, featuring Luca Signorelli

Civita di Bagnoregio is a town in the Province of Viterbo in central Italy, a suburb of the comune of Bagnoregio. The town is noted for its striking position on top of a plateau of friable volcanic tuff overlooking the Tiber river valley. It is in constant danger of destruction as the edges of the plateau collapse due to erosion, leaving the buildings to crumble as their underlying support falls away. As of 2004, there were plans to reinforce the plateau with steel rods to prevent further geological damage. The city is also much admired for its architecture spanning several hundred years. Civita di Bagnoregio owes much of its unaltered condition to its relative isolation; the town was able to withstand most intrusions of modernity as well as the destruction brought by two world wars. The population today is 11 people, but due to a healthy amount of bnb’s the village gets busy in the summer months. Admission not included.
