A region of such great strategic importance in European history, at the crossroads between the German civilization and the Mediterranean, always had imposing, powerful fortresses and sighting towers along the natural borders of the rivers Ticino, Adda and Po and the huge lakes; some of these are among the most impressive in Italy, as the Vigevano castle, and many rise in positions of great beauty, as those on Lake Maggiore, or have been transformed in rich mansions as those of the Sforza family.
