The original Cathedral of San Zeno (5th century) burned down in 1108, but was rebuilt during the following century, and received incremental improvements until the 17th century. The façade has a prominent Romanesque style, while the interior received heavy Baroque additions which were removed during the 1960s. Its outstanding feature is the Altar of St James, an exemplar of the silversmith's craft begun in 1287 but not finished until the 15th century. Its various sections contain 628 figures, the total weighing nearly a ton. The Romanesque belfry, standing at some 67 m, was erected over an ancient Lombard tower.
