Lonely Planet review for El Morro
A six-level fort with a gray, castellated lighthouse, El Morro juts aggressively over Old San Juan’s bold headlands, glowering across the Atlantic at would-be conquerors. The 140ft walls (some up to 15ft thick) date back to 1539, and El Morro is said to be the oldest Spanish fort in the New World.
