The trajectory of the Fortress dates back to 1762, when the Portuguese, foreseeing a new conflict with Spain, decided to fortify the place, at that time called Castillos Chicos. Its walls were built of a double stone wall of masonry and joined by stirrups. The space between both was filled with soil and rubble to form the patrol path and to resist the vibrations of the firings of the enemy artillery. Within this monument you can feel centuries of history. It passed into the hands of the Orientals in 1825, and remained abandoned for a long time until it was rediscovered by the historian Horacio Arredondo, who began the efforts for its reconstruction in 1928.
