Things to do in San Juan

Old San Juan

Old San Juan, home to almost 500 years of world-class architectural and historical identity, is the older part of the city of San Juan. Visitors can see its historic forts and more than 400 beautifully restored 16th- and 17th-century colonial buildings. Main highlight here is the Fuerte San Felipe del Morro, a fortress set on an elevated land overlooking the sea.

Fuerte San Felipe del Morro

Fuerte San Felipe del Morro is a 16^th century fortress constructed on a point of land just above the Atlantic Ocean. The fort was completed over a period of 250 years as it was continuously subjected to many pirate raids and attacks from the sea pirates. Today, it features a maze of ramps, outposts, barracks, dungeons, and tunnels that are all sprinkled with circular sentry boxes.

Castillo de San Cristobal

Castillo de San Cristobal is the largest fort ever erected by the Spanish in the Americas or the New World. The fort is spread across more than 27 acres with 5 individual units linked by moat and tunnel. The difference between El Morro and the Castillo is that the former was constructed to guard against attacks by sea while the latter was constructed to guard against a land-based attack.
