The Old Town of Canzo preserves the sites of the ancient communal and pieval system: the seat of the governor and of the federal jails were in the street later named "Cuntrada dal pretòri"; the communal assembly was in a place that gave its name to the "Cuntrada dal cuèrc" (street of the porch); a fort, later occupied by the Spanish rulers in their first phase, was probably not far from the "pretòri", in the street now known as "Turèta" (little tower street); another tower was on an elevated site looking toward "Crann" and the little valley in front of it.
