Roman marble slabs of perusal can be seen at the base, while the two upper floors with the clock were added in the eighteenth century. Nearby is the bishop's palace, also from the 16th century. Both are part of the cathedral complex, consecrated in 1113 to Our Lady of the Assumption and Saints Philip and James.
A harmonious overlap and synthesis of architectural styles, a treasure trove of valuable works of art from different periods, right down to valuable inlaid panels from the first half of the 20th century, the 12th-century cathedral was repeatedly enlarged and even rebuilt after the Saracen destructions of 1558, only to be radically transformed in Baroque style in the 18th century. Of particular value are the paintings by Giacomo del Po in the Presbytery, depicting the Assumption and Saints Philip and James. And the 1340 marble bas-reliefs signed by Andrea Pisano in the first chapel on the left, in the center of which is the baptismal font where Torquato Tasso was baptized. Ė composed of Roman and 16th-century parts is the bishop's chair, while the wooden statue of St. Antoninus is 18th-century. Also from the 18th century is a rare Neapolitan nativity scene. In the sacristy, precious sacred furnishings and vestments and parchment antiphonaries from the 15th century are on display.
