Trento Cathedral (Italian: Cattedrale di San Vigilio, Duomo di Trento; German: Kathedrale Trient; Trentino dialect: Dòm) is the main church in the city of Trento. It serves as the cathedral of the Archdiocese of Trento and was elevated to the rank of minor basilica by Pope Pius X on 18 March 1913. It was also designated an Italian national monument by royal decree in 1940.
Originally constructed as a cemetery basilica, the cathedral was founded in the 4th century by Saint Vigilius to house the remains of the martyrs of Anaunia. It has undergone several construction phases over the centuries. Notably, a complete reconstruction was initiated by the Prince-Bishop Federico Vanga in the early 13th century and continued into the 16th century, resulting in the current Romanesque-Gothic forms. Subsequent modifications have further shaped the structure. The remains of the ancient Paleochristian Basilica of San Vigilio are preserved and displayed beneath the current floor level.
