With its landmark black-and-white bell tower, Viterbo's 12th-century duomo looms over Piazza San Lorenzo, the religious nerve centre of the medieval city. Originally built to a simple Romanesque design, it owes its current Gothic look to a 14th-century makeover and a partial post-WWII reconstruction.
Many of its treasures are today housed in the adjacent Museo Colle del Duomo , including a reliquary said to contain St John the Baptist's chin.
