The Insubres lived free and independently until the arrival of the Gauls, led by Belloveso, who, around the year 600 BC, undid the Insubres and settled in Milan and Como, occupying the shores of the lake and creating a garrison at the extreme point of their conquest, Bellagio (fancifully Bellasium, named after their commander Belloveso). The Gauls thus became Gallo-Insubres, merged with the primitive inhabitants and introduced their customs and traditions, leaving traces in local names: Crux Galli (now Grosgalla), on the side of Lezzeno, and Gallo, a small chapel on the old road of Limonta which marks today the border between the two municipalities.
