Castle of San Felipe de Lara, it is composed for defensive strength that watched over the entrance to the old Kingdom of Guatemala from the Caribbean sea, built during the time of Spanish dominance (1524-1821). Located at the mouth of Lake Izabal in eastern Guatemala. The Dulce River, along with El Golfete, connects Lake Izabal with the Caribbean Sea, historically exposing it pirate attacks. King Philip II of Spain ordered the fort to be erected in an attempt to quell the plundering by the pirates (Wikipedia).
