The cathedral, which was built in the Lombard period, was destroyed by bombardments during the Second World War. Reconstructed under the leadership of architect Paolo Rossi de Paoli, it retains a few surviving Romanesque elements: the facade and the large bronze door, known as the Janua Major. The interior, with its rich Cosmatesque floor, is home to the marble statue of Saint Bartholomew on the Throne and two fourteenth-century pulpits attributed to Nicola da Monteforte.
