in the valley of the Castrum Sibrium
Castelseprio and Gornate Olona, in the province of Varese, are sited in a strategic position in the heart of the River Olona valley, connected by land and river to Alpine passes and central Europe. Castelseprio has been known since Late Antiquity (4th-5th centuries) as a fortification and military camp, then further strengthened by the Goths in the following two centuries, when an imposing wall with towers was built, which extended to include Torba at the bottom of the Olona valley.
This territory includes innumerable Lombard period remains, including the funerary inscription of Wideramn, an entire knight’s outfit and the monuments of the Castelseprio Archaeological Park.
The councils of Castelseprio and Gornate Olona are founding partners of the Italia Langobardorum Association. This part of the UNESCO Serial Site is made up of the Castrum, Torba monastery and the church of Santa Maria Foris Portas.
