Castillo de los Tres Reyes del Morro rises on a rocky headland at the mouth of Havana Bay, its stone ramparts and lighthouse framing the narrow harbour channel that once controlled access to Cuba’s capital. Built under Spanish rule between the late sixteenth and early seventeenth centuries, the fortress is closely associated with the Italian military engineer Giovanni Battista Antonelli and the reign of Philip II of Spain.

Seen from the old city across the water, Castillo de los Tres Reyes del Morro occupies a commanding position on a promontory that marks the entrance to the bay. The headland lifts the walls high above sea level, giving wide views over the harbour approaches and the coastline beyond.
