Fort Fuentes: Defending Italy's Northern Border, Until Napoleon's Conquest and

Located near Colico, Italy, Fort Fuentes was constructed between 1603 and 1609 by Don Pedro Enríquez de Acevedo, Count of Fuentes. Its purpose was to safeguard the Pian di Spagna and the strategic Trivio di Fuentes, warding off threats from the Grisons to the north. The architectures of the fortress and related structures, such as the tower of Sorico, the Torretta del Passo, and the Fortino d'Adda, among others, were designed by Gabrio Brusca and completed in three years.

However, its military usefulness was short-lived. Surrendering to Prince Eugène of Savoy in 1706, Fort Fuentes was later deemed militarily useless by Emperor Joseph II in 1769, leading to its decommissioning in 1782. Its hill was auctioned to a private buyer, and the fortress was largely demolished by General François Rambeau on Napoleon’s orders in 1796 and at the request of the Grisons. For the remainder of the 19th century, the fort's ruins served as a hiding place for bands of bandits whom the Austrian gendarmerie were unable to dislodge.
