Forte di Fuentes, is a former military fort on the hill of Montecchio or Monteggiolo near Colico, in the province of Lecco, Lombardy, northern Italy.

The Fortress is of Spanish origin from the seventeenth century built by the Governor of the State of Milan, Pedro Enriquez de Acevedo, Count of Fuentes, to prevent any expanding ambition by Three Grey Leagues (modern Swiss Grisons) that wanted to enlarge their domain from the Valtellina and Valchiavenna up to the High Como Lake.

The Forte was destroyed in 1796 by Napoleon's troops and General Rambeau under Napoleon's Command. At the time, however, it was no longer a military fortress.

A small excursion that you reach after a few minutes of walking on the path that climbs a small mountain in a quiet location, surrounded by woods, fields and farms where you find yourself with a a panoramic terraces on the fabulous Pian di Spagna, the Adda river that flows into Lake Como,  and the mountains of Valtellina and Valchiavenna.

The surrounding area offers many excursions and walks.
