A 15 minute drive from Giove brings you to one of the most ancient Umbrian towns, Amelia. Enveloped by impressive polygonal walls dating from the 4th century, the sights are mainly medieval, but underground the network of wells built by the Romans can still be visited today.
The town of Narni (30 mins) also has much to discover below ground. You can take a tour of ‘Narni Sotterranea’, an excavation directly under the Church of San Domenico, to learn some local history with a look into Roman plumbing (!) and even an underground Roman church with surviving frescoes.
Orvieto (30 mins) warrants a full day. Its vast black and white striped Gothic cathedral is the centrepiece, visible from miles around on its rocky outcrop. Signorelli’s majestic treatment of the ‘Last Judgement’ should not be missed in the Brizio Chapel, and the little museum next door has some good Etruscan finds.
Todi and Viterbo are also worth visiting in this region.
