First-time visitors to Old San Juan simply cannot leave without visiting Castillo San Felipe del Morro. Called El Morro (which means "promontory" in Spanish), the fortress encapsulates Puerto Rico’s role as a guardian of the New World. Perched on the northwestern-most point of Old San Juan, this daunting citadel must have been an intimidating sight to enemy ships. Within these walls, you can feel the awesome power this bastion of defense once commanded, and you can bear witness to nearly 500 years of military history that began with the Spanish conquistadores and ended with World War II.

History of El Morro

El Morro, part of the San Juan National Historic Site, is Puerto Rico's most picturesque military structure. The Spanish began construction in 1539, and it took more than 200 years to complete. In its entire history, the intimidating fortress has successfully blocked every naval attack, even when England's Sir Francis Drake tried to breach its walls in 1595. El Morro fell only once, when England's George Clifford, Earl of Cumberland, took the fortress by land in 1598. Its usefulness continued into the 20th century when it was used by the United States during World War II to track the movements of German submarines in the Caribbean.

Things to See and Do

You’ll follow in the Earl of Cumberland's footsteps as you cross a large green field to get to the fort. It is a bit of a walk to get to it, and you'll need to be able to climb steps and steep slopes.

Once you reach the citadel, take your time to explore its ingenious architecture. El Morro is made up of six staggered levels, incorporating dungeons, barracks, passageways, and storerooms. Walk along its ramparts, where cannons still face the ocean, and step inside one of the domed garitas (sentry boxes), which are themselves an iconic symbol of Puerto Rico. The garitas are the prime places to find breathtaking ocean views. Looking out across the bay, you'll see another, smaller fortification. Called El Canuelo, this was El Morro’s partner in the island’s defense: Ships hoping to attack Puerto Rico would be cut down in a barrage of crisscrossing cannon fire.

Two modern structures were added to El Morro after Puerto Rico was ceded to the United States by Spain in 1898 as a result of the Spanish-American War. A lighthouse, which was repaired by the U.S. from 1906 to 1908, stands out in stark contrast to the rest of the structure. During World War II, the U.S. Army added another entirely incongruous fortification, installing a military bunker on the top level.

During your visit, you'll also find exhibits and a theater—which plays a park film in both English and Spanish—that dive even further into the fort's history.

In addition to its historic importance, El Morro serves as a beacon for relaxation and photo ops: People come here to relax, picnic, and fly kites; the sky is full of them on a clear day. (You can buy one—they're called chiringas—at a nearby stall.)

For incredible views of the city, take to the Paseo del Morro boardwalk, a 1-mile trail that runs between El Morro's outer walls and the Bay of San Juan.


There is a sidewalk with an accessible grade leading up to El Morro; however, there is no parking at the entrance. From the main plaza, which is on the fifth level, the bookstore and theater are accessible. The sixth level can be reached by a steep ramp, but the lower levels are not accessible. The National Park Service warns visitors that the site features uneven surfaces, steep ramps and staircases, and dimly lit tunnels and passageways.

Visitors can pick up assisted listening devices at El Morro, while park brochures are available in English, Spanish, and Braille. For other requests, you can contact the Chief of Interpretation and Visitor Services at 787-729-6777.

Other Attractions Nearby

San Juan National Historic Site, designated a UNESCO World Heritage Site in 1983, is also home to Castillo de San Cristóbal (Saint Christopher's Castle), located 1.2 miles east of El Morro. The largest fortress constructed in the Americas, it took more than 150 years to complete its three levels and outer defenses, which include a series of tunnels and a dry moat. Placed underneath San Cristóbal's main plaza are five cisterns; built to catch about 800,000 gallons of rainwater, they are still in use today. Its display of innovative 18th-century military engineering is perhaps San Cristóbal's biggest draw, although you can also enjoy 18th-century drawings, two coastal observation posts, and the visitor center, housed in a 1942 bunker.

About a 15-minute walk southeast of El Morro is La Fortaleza (The Fortress). Originally built in 1540 to protect the city from attack, it was renovated in 1846 and has served as the official residence of the Puerto Rican governor ever since. Visitors can take a 30-minute guided walking tour of the gardens and building, from 8:15 a.m. to 3:30 p.m. Monday through Friday.
