Fort Fuentes

Fort Fuentes, Italian: 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.

It was built by the Spanish governor of Milan, Don Pedro Enríquez de Acevedo, Count of Fuentes, to command the Pian di Spagna and the strategic Trivio di Fuentes, the crossroads between the Valtellina, the Valchiavenna and the Alto Lario, in order to defend the northern border of the Spanish domain against the Grisons to the north. Construction was begun in 1603 or October 1609 under military architect Gabrio Brusca, and was substantially complete within three years.
