It had served the people around Lake Constance (Bodensee) for 1200 years, and survived almost 100 bishops. General restoration work took place on the Cathedral from 1844 to 1860; the tower was raised in neo-Gothic architectural style. In 1955 Pope Pius XII raised the Cathedral to a papal Basilica Minor. A restoration program of the Cathedral’s interior as well as exterior started in 1962 and was expected to be completed by 2010. In 1966, twelve new bells were cast and hung in the center tower and the ridge turret, a present from the state of Baden-Württemberg.
