Basilica of San Pietro in Ciel d'Oro
The Basilica of San Pietro in Ciel d'Oro was built at the beginning of the 8th century, in the middle of the Lombard era and is called St. Peter in the Golden Sky because of its golden ceilings. The church was reconsecrated by Pope Innocent II in 1132 after major renovations in Romanesque style. Having fallen into a state of abandonment and ruin after the Napoleonic period, the basilica was restored and partially rebuilt between 1875 and 1899.
