雷定五世
The church of Santa Maria di Collemaggio, just outside the town, has a very fine Romanesque façade of simple design (1270–1280) in red and white marble, with three finely decorated portals and a rose-window above each. The two side doors are also fine. The interior contains the mausoleum of Pope Celestine V erected in 1517. Many smaller churches in the town have similar façades (S. Giusta, S. Silvestro and others).
