Castillo de los Tres Reyes del Morro and its harbour-facing walls

Castillo de los Tres Reyes del Morro occupies a rocky promontory at the entrance to Havana Bay. Its bastioned walls, sea-facing position and lighthouse form a powerful architectural composition, begun in 1589 under Philip II of Spain.
Castillo de los Tres Reyes del Morro above Havana Bay
The fortress rises across the water from Havana’s historic centre. Its walls follow the contours of the promontory, creating a broad military complex of ramps, terraces, parapets and angular bastions.
The site belongs to the Spanish colonial military architecture of the late sixteenth and early seventeenth centuries. Giovanni Battista Antonelli, an Italian engineer in Spanish service, is associated with its design. Italian engineer Battista Antonelli helped shape the fortress’s Renaissance military character.
From Philip II to the completed fortress
Construction began in 1589 during the reign of Philip II. Work continued into the early seventeenth century, and the fortress reached its completed form in 1630. Construction between 1589 and 1630 places Castillo de los Tres Reyes del Morro within the Spanish Empire’s fortified Caribbean ports.
The castle guarded the entrance to Havana’s harbour as part of a defensive system that included other fortifications around the bay. British forces captured Havana in 1762, and Spanish control returned under the Treaty of Paris in 1763. The fortress therefore carries a clear record of imperial rivalry in the Caribbean.
A lighthouse above Renaissance fortification
The lighthouse gives the fortress its most recognisable vertical feature. A lighthouse was installed at the castle in 1845, adding a maritime function to the heavy walls and watch positions of the military complex.
From the promontory, the fortress presents two distinct faces. Landward walls, moats and bastions express defensive architecture, while the lighthouse and open sea connect the site with Havana’s harbour history. The lighthouse installed in 1845 remains part of the castle’s visual identity.
