Castillo de los Tres Reyes Del Morro

The Castillo de los Tres Reyes del Morro (English: Castle of the Three Kings of Morro), also known as Castillo del Morro (Morro Castle), is a fortress guarding the entrance to the Havana harbor. The design is by the Italian engineer Battista Antonelli (1547–1616). Originally under the control of Spain, the fortress was captured by the British in 1762, returned to Spain under the Treaty of Paris (1763) a year later. The Morro Castle was the main defense in the Havana harbor until La Cabaña was completed in 1774.
