The Cathedral Museum and Crypt of St Rufino was founded in 1941. Visitors here can see the various archaeological remains, beautiful paintings, capitols, and religious vestments. At the end of the regular museum tour there is a visit to the 11th Century crypt of St Rufino, which is directly beneath the cathedral façade. Here there are frescoes from the 12th Century as well as a Roman sarcophagus that was used to bury the saint.
