What is the history of the Sant'Orso Crypt?
The crypt dates back to the 11th century, during the time of Bishop Anselmo I. Before the construction of the collegiate, the area was a Roman necropolis. In the following centuries, a Carolingian basilica was built, which was later expanded. The crypt is thus one of the oldest spaces in the entire religious complex of Sant'Orso, a true bridge between the Roman era and the Middle Ages.
How is the Sant'Orso Crypt structured?
The crypt is divided into five naves that end in three semicircular apses. It is supported by numerous columns, some of which are elements of Roman recovery, such as an ancient milestone. This mix of ancient and medieval elements creates a suggestive and unique atmosphere.
What can be seen inside the Sant'Orso Crypt?
Inside, one immediately notices the forest of columns that supports the vaults. In front of the altar is a statue of Sant'Orso, the patron saint of the collegiate. In the past, beneath the altar, there was a small sacred passage: the faithful would crawl through it on their knees on the feast day to seek protection from diseases and pains. This popular tradition adds charm to the visit.
