Visit El Morro, Puerto Rico's most iconic fortress, to explore nearly 500 years of history, breathtaking ocean views, and one of the Island's most treasured landmarks.
Few landmarks are more representative of Puerto Rico's legacy within the Caribbean and the Americas than Castillo San Felipe del Morro, better known as El Morro. Standing at the northwestern tip of Old San Juan, this iconic fortress greets cruise ships as they sail in and out of San Juan Bay. During most of its nearly 500-year history, it served as a strategic military outpost for Spain and later the United States.
When you walk through the narrow entrance and see the flags waving in the Atlantic breeze, it's easy to be transported to another time in history. Imagine soldiers in historic uniforms marching along the walls, where cannons once stood ready to defend the Island from approaching ships.
When you visit El Morro, you'll discover not only the story of one of Spain's greatest military engineering achievements in the Americas, but also how Puerto Rico's strategic location shaped the Island's history, from Spanish colonization to the First and Second World Wars.

For centuries, El Morro protected the entrance to San Juan Bay from attacks by sea.
A Brief History of El Morro
Old San Juan was founded in 1521 by Spanish settlers. The first fortification, La Fortaleza (The Fortress), began construction in 1533 and currently serves as the governor's mansion. The Castillo San Felipe del Morro was the second fort built on the islet of what is now Old San Juan and Puerta de Tierra. Construction of El Morro began in 1539 and was completed in 1790. During those 250 years, the fortress evolved from a simple promontory with a cannon into a six-level military stronghold designed to discourage attacks from the sea.
About half a mile across the entrance to San Juan Bay stands Fortín San Juan de la Cruz, better known as El Cañuelo. Together, the two forts created a powerful crossfire that protected the bay entrance and the city beyond. Thanks to El Morro (and El Cañuelo), the Spaniards were able to defend Puerto Rico from invasions by the British, Dutch, and pirates.
Following the Spanish-American War in 1898, Puerto Rico became a United States territory. El Morro became part of Fort Brooke and continued serving as a military installation during both World War I and World War II.
In 1961, the U.S. Army transferred El Morro to the National Park Service, preserving it as a museum and historic site. In 1983, El Morro and the historic fortifications of Old San Juan were designated a UNESCO World Heritage Site, recognizing their outstanding cultural and historical significance.
Local Tip: Before entering the fortress, spend a few minutes on the expansive lawn outside El Morro. It's a favorite gathering place for local families, especially on breezy afternoons, when flying colorful kites against the backdrop of the Atlantic Ocean has become a cherished Puerto Rican tradition.

What to Wear
Wear lightweight, weather-appropriate clothing and comfortable shoes with good traction. Much of the fortress's inner courtyard is exposed to the sun and can become warm during the day. Loose-fitting, light-colored clothing. If you're visiting during or after rain, keep in mind that the stone ramps connecting the different levels can become slippery. Since El Morro sits on a bluff overlooking the Atlantic Ocean, it is often breezy. Hats should fit securely, and skirts or loose dresses may not be the most comfortable option on particularly windy days.
