Another multi-centred site, Longobards in Italy, Places of Power (568–774 A.D.), comprises seven locations across mainland Italy which illustrate the history of the Lombard period which has given the region its name. Two of the individual sites are in the modern region of Lombardy: the fortifications (the "castrum" and the Torba Tower) and the church of Santa Maria "foris portas" ("outside the gates") with its Byzantinesque frescoes at Castelseprio, and the monastic complex of San Salvatore-Santa Giulia at Brescia. The UNESCO site of Brescia also includes the remains of its Roman forum, the best-preserved in Northern Italy.
