Colico was chosen as the site of this fort for its position at the end of the Tellina valley, a route traditionally used by invading armies. It was completed at the end of 1914 and was Italy?s most technological military installation in World War I. The four canons, which are still the biggest in Italy, are in working order and can fire with precision from a distance of over 14 kilometres. From its commanding position, the fort enjoys spectacular and unique views of lake Como and the mountains of the Tellina and Chiavenna valleys.
