Castillo de los Tres Reyes del Morro above Havana’s harbour channel

Castillo de los Tres Reyes del Morro watches over the harbour entrance of Havanna, combining Spanish imperial power, maritime history and wide views across the bay.

Castillo de los Tres Reyes del Morro is the stone fortress that commands the narrow entrance to Havana Bay, rising on the rock known as El Morro above the harbour channel of Havanna. Built under Spanish rule in the late sixteenth and early seventeenth century and attributed to the Italian military engineer Giovanni Battista Antonelli, it anchors Havana’s historic skyline with its bastioned walls and lighthouse.

A Spanish imperial fortress on El Morro

The Castillo de los Tres Reyes del Morro was conceived as part of the Spanish Empire’s Atlantic defence system during the period when Havana developed into a key port for transatlantic fleets. Construction began under the reign of Philip II of Spain in 1589 and continued into the early decades of the seventeenth century, giving the fortress its late Renaissance military character.Built between 1589 and 1630 The design is credited to Giovanni Battista Antonelli, one of the most prominent engineers of Spanish colonial fortifications in the Caribbean.

The castle stands on a rocky promontory called El Morro at the eastern side of the bay entrance, directly opposite the area now known as Old Havana. Its position allowed cannons to command the narrow channel that leads into the harbour, controlling access for ships sailing between the Gulf of Mexico, the Caribbean and Spain.The fortress guards the harbour entrance Stone ramparts descend towards the sea, with walls built to withstand artillery fire and waves.

Layout, bastions and lighthouse

Seen from the water, Castillo de los Tres Reyes del Morro presents a compact mass of masonry articulated by bastions and parapets adapted to the irregular rock platform. Antonelli’s plan is described as a triangular fortress with angular bastions, moats and internal galleries, a geometry typical of late sixteenth-century coastal defences.A triangular fortress with angular bastions Inside, enclosed yards and casemates open off the main circulation routes, with gun platforms oriented towards both the sea and the bay.

One of the most recognisable features of the complex is the lighthouse that rises above the seaward side of the fortress. This tower, added in the nineteenth century and recorded as dating from 1844, gives the castle a vertical marker visible far out at sea and across the city.The lighthouse was added in 1844 The contrast between the older low bastions and the later lighthouse emphasises how the site bridges different periods in Havana’s maritime history.
