Castillo San Felipe del Morro

Castillo San Felipe del Morro is a Spanish colonial citadel begun in the sixteenth century to guard San Juan Bay, now part of San Juan National Historic Site under the U.S. National Park Service. Ramparts, garitas, and a green campo create one of the Caribbean’s great fortress landscapes. Centuries of siege and hurricane define its record.

Haunt folklore of soldiers and prisoners circulates among visitors and local guides. NPS signage stresses military engineering and colonial history. Sunset walls feel cinematic without needing a verified ghost.

NPS fees may apply; bring sun protection and water.

NPS historic site with daytime hours, exposed ramparts, and drop hazards into the Atlantic. Heat and slippery stone after rain. Old San Juan streets nearby are cobbled and crowded. No public overnight stays on the walls—leave at closing.
