Fort San Felipe del Morro, or El Castillo San Felipe del Morro in Spanish, is a 16th century citadel on the northwestern-most point of San Juan. Named in honor of King Philip II of Spain, the fort was designed to guard the entrance to San Juan bay and defend the city from seaborne invaders. In 1983, it was declared a World Heritage Site by the United Nations. Over two million visitors a year explore the windswept ramparts and passageways, making the fort one of Puerto Rico's main attractions.

During the 1640 reconstruction, the chapel of Santa Catalina, then located outside the walls, was demolished and was integrated into it, which gave rise to another name for which it is known, Palacio de Santa Catalina.
