The Castillo de San Felipe del Morro, (more commonly known as El Morro) is Old San Juan’s most recognizable landmark. For over 400 years, it has protected San Juan and the shipping route from the New World to the Old. Today, a visit to this six-level citadel is like walking through a military history of Puerto Rico from the 1500s to the 20th Century. Pass by cannons still facing the ocean, step inside a sentry box, see how the soldiers used to live and work in colonial times, and check out the enhancements made by the U.S. during World War II.
