San Felipe del Morro Fort (El Morro)
El Morro, officially known as Fuerte San Felipe del Morro, sits atop a high peninsula overlooking the entrance to San Juan Bay. It is the result of the efforts of many different Spanish engineers over a period of more than 200 years and is one of the largest forts built by the Spaniards in the Caribbean. Although the foundations were laid in 1539, the six-level fort was not considered completed until 1787.
This massive structure suffered countless attacks from the likes of Sir Francis Drake in 1595 and the Dutch fleet in 1625. In 1898 American ships fired on it during the Spanish-American War, destroying its lighthouse, which was later restored. Visit hidden passages, aim your camera on the cannons that still guard the harbor, and gaze over the 60-foot tall walls at the ocean. Stroll on the lawns where soldiers once marched and watch the children flying their kites in the afternoon sea breezes.
