Built in 1560 according to the wishes of the Uri mercenary leader Peter A Pro, as a military base for the recruitment of mercenaries. The complex includes one massive square-plan building with a projecting top part, with walkway and machicolations. Adjacent is a rectangular two-floor building, with iron gratings on the ground floor windows. Inside are corridors and hiding places. It’s also known as “La Vignaccia”. Close to Minusio are also the ruins of the “Fraccia”, a wall with towers built during the Fourteenth Century. Unfortunately, it's not open to the public.
