El Morro (which translates as "promontory") is a fortress built by the Spaniards between 1540 and 1783. Rising 140 feet above the sea, a massive six-level fortress with a labyrinth of dungeons, ramps, barracks, turrets, towers and tunnels features its own Santa Barbara Chapel. Built to protect the port, El Morro has a commanding view of the harbor. The area was designated a National Historic Site in February, 1949 with 74 total acres.

 

Castillo San Cristobal Fort was El Morro's partner in the city's defense. Built in the 18th century, was considered the Gibraltar of the West Indies. San Cristobal was supported by a massive system of outworks which provided defense in depth and is is one of the largest defenses ever built in the Americas.
