Castillo San Felipe del Morro
historicalPuerto Rico's most iconic landmark, El Morro is a massive 16th-century fortress that took over 200 years to complete. This six-level citadel juts into San Juan Bay and offers spectacular Atlantic Ocean views, a maze of tunnels, barracks, and prison cells to explore. The surrounding esplanade is perfect for kite flying and watching stunning sunsets. A UNESCO World Heritage Site since 1983, El Morro tells the story of centuries of Spanish colonial defense.
