1599. To the west of the monastic complex is the monumental area consisting of the Capitolium, the republican sanctuary and the Roman theatre, closely linked with the stories about San Salvatore-Santa Giulia. The oldest religious building of the Roman forum dates back to the end of the first century BC. The exceptional level of conservation of the architectural and decorative aspects makes this archaeological area a unique example in northern Italy. Castrum with Torba Tower and church outside the walls, Santa Maria foris portas, at Castelseprio The castrum with the Torba Tower and the church outside the walls at Castelseprio (Province of Varese) includes the Torba Monastery, the Santa Maria foris portas church with its frescoes, and the ruins of the San Giovanni Evangelistic basilica. The Longobards turned the Castelseprio Castrum, which was previously a Roman military outpost and an Ostrogoth defensive bastion, firstly into a place for commerce and then into a monastery (8th century). The monastery includes the tower, built by the Ostrogoths and re-adapted for monastic purposes by the Longobards, and also the little church named after the Virgin Mary. Only the ruins of the big Castelseprio Basilica remain, three naves with a central apse and absidium, however the Santa Maria foris portas has remained intact, including large parts of its apsidal frescoes, which are some of the largest murial paintings found from the entire period of the Early Middle Ages. Basilica of San Salvatore at Spoleto The basilica of San Salvatore at Spoleto (Province of Perugia) was an Early Christian basilica from the 4th-5th century, on which the Longobards carried out extensive renovations during the 8th century. The basilica was built with three naves: also the chancel is tripartite and it is covered by a vault with an octagonal base. The apse is a semicircle and is closed off on the outside by a straight wall. At either side of the flank are two apse areas with a ribbed vault. The inside has lost its original decorations of stuccos and paintings, but preserves a rich entablature with Doric frieze, set on Doric and Corinthian columns. On the original 8th century facade, marked by lesenes and divided in to two sections from one corner, only the corners of the windows and the three portals sculpted with classic motifs have managed to be preserved.
