Castillo de los Tres Reyes del Morro stands on a rocky headland at the entrance to Havanna’s harbour, its stone ramparts and lighthouse forming a fixed point in the city’s historic skyline. Rising above the narrow channel into the bay, the fortress combines late sixteenth-century Spanish military engineering with the later nineteenth-century lighthouse tower that turns its rugged outline into a clear maritime landmark.
