Castillo San Felipe del Morro

A six-story Spanish fortress guarding the entrance to San Juan Bay. It withstood attacks from the English, Dutch and Americans, and forms the heart of the San Juan National Historic Site.

Castillo San Felipe del Morro, known as El Morro, was begun in 1539. Over more than two centuries it was expanded into a six-story fortress with walls several meters thick, guarding the entrance to San Juan Bay. It was attacked by the English under Drake in 1595, by the English under the Earl of Cumberland in 1598, and by a Dutch fleet in 1625. During the Spanish-American War in 1898, it was bombarded by US forces. Inside, visitors can explore the gun batteries, barracks, gunpowder magazines, the lighthouse and the sentry boxes (garitas), the iconic symbol of Puerto Rico. The views of the sea from the top level are excellent. The large lawn in front of the fortress is where locals fly kites and picnic on weekends. The fortress is managed by the US National Park Service. Admission is about 10 US dollars (free for those under 15), and the same ticket is valid for San Cristóbal Castle on the same day. There are English and Spanish guided explanations. The ramparts offer no shade, and the afternoon heat can be intense, so stay hydrated and wear sun protection.
