This unusual fortress is actually a prison for mob figures from Sicily. The park nearby was the Acropolis of Volterra for 3000 years until Florence burned it down and turned it into a park.
Museo Etrusco Guarnacc
One of the best places in Europe for Etruscan art, it is filled top to bottom with it, though there are few English explanations.
Volterra's city hall is probably the oldest in Tuscany, at nearly 800 years, and inspired the design for the Palazzo Vecchio in Florence. The lavishly painted city council chambers are open to the public when not being used for official meetings.
Great pulpit and altar. Notice how the entrance is through the baptistry, you couldn't enter until you were baptized.
The town's best site is this gate built of massive volcanic stones in the 4th century BC. It's part of the town walls that were 4 miles around, twice as big as it is now.
A small 3-room museum of church art. Well explained in English.
