The Cathedral Museum of San Lorenzo, also known as the Cathedral Museum, is located in Perugia in the historic center. The Museum was founded in 1923 and develops in 25 rooms that house the works coming from churches in the diocese and the Cathedral. At the entrance of the museum it is located on the archaeological site of the Cathedral where originally stood the Etruscan acropolis.
