Santa Maria di Collemaggio is a large medieval church in L'Aquila, central Italy. It was the site of the original Papal Jubilee, a penitential observation devised by Pope Celestine V, who is buried there. The church, which therefore ranks as a basilica because of its importance in religious history, sits in isolation at the end of a long rectangular sward of grass at the southwest edge of the town.
The church is a masterpiece of Abruzzese Romanesque and Gothic architecture and one of the chief sights of L'Aquila. The striking jewel-box effect of the exterior is due to a pattern of blocks of alternating pink and white stone; the interior, on the other hand, is massive and austere. Outbuildings include a colonnaded cloister, with the central fountain typical of many other similar Italian cloisters, and the former monastic refectory.
