High on a volcanic cliff of red tufa, lies the historically and culturally rich city of Orvieto. Visiting this town is like traveling through history.

In the center of town is a 13th century Palazzo Communale, the Church of Sant' Andrea, and one of the most important monuments in Umbria, the Cathedral.

40 km from Castel di Fiori.
