Orvieto is a small city perched on a rock cliff in Umbria, Italy. Duomo di Orvieto, dating from 1290, has a mosaic facade and houses a marble Pietà sculpture. The Pozzo di San Patrizio is a 16th-century well shaft with a double spiral staircase. An underground cave network attests to the city’s Etruscan roots. Artifacts from this era, like ceramics and bronze items, are on view at the National Archaeological Museum.
