The Archaeological Museum has been set up in Santa Maria della Scala’s expressly restored underground rooms, which were used as storerooms, warehouses and technical spaces. The museum presents archaeological collections and materials coming from the Sienese territory exhibited on a surface of approx. 2500 square metres. It can be visited following a highly evocative continuous sequence in which works are arranged according to topographic criteria along with pieces from the collections that progressively became part of the Sienese museum.
