Orvieto Cathedral (Italian: Duomo di Orvieto; Cattedrale di Santa Maria Assunta) is a large 14th-century Roman Catholic cathedral dedicated to the Assumption of the Virgin Mary and situated in the town of Orvieto in Umbria, central Italy.

Situated in a position dominating the town of Orvieto which sits perched on a volcanic plug, the cathedral’s facade is a classic piece of religious construction, containing elements of design from the 14th to the 20th century, with a large rose window, golden mosaics and three huge bronze doors.
