San Juan National Historic Site

The San Juan National Historic Site is one of the most popular attractions in Puerto Rico and a top Caribbean site too.

When visiting this national historic site, you can visit three sites – the San Cristóbal forts, San Felipe del Morro and the San Juan de la Cruz (El Cañuelo) and city walls.

Explore tunnels at the San Juan National Historic Site, navigate ramparts and barracks, and get spooked in the dark dungeons.

San Juan National Historic Site is steeped in 500 years of history.

History buffs and those interested in colonial history will find this a fascinating place to visit.

San Juan was the final loading port for products being shipped back to the Spanish colonisers.

The area of San Juan and the fort was one of the most important Spanish outposts in the region in the 16th century.

This colonised city was ideally located for transporting all the gold and silver taken from the Caribbean back to Spain.

Because of this, San Juan needed a strong fortification, especially to fight against pirate invasions. A fun way to explore is on a Cocktail Walking tour, where you drink cocktails and learn about history as you stroll through Old San Juan.

Things to do at San Juan National Historic Site

1- Visit Castillo San Felipe del Morro

Also known as El Morro, this is an impressive citadel right in the heart of the massive fortification.

This large fortification was first built in the 16th century and consists of six staggered levels, all with their own unique elements.

The construction of El Morro began in 1539 by the Spanish and was the second fortification in San Juan to be built.

It wasn’t until 1790, 251 years later, that the fortification was complete.

By the time it was completed, there were six complex levels to the fort in a tiered design chosen to distract the enemy and make it confusing for attackers. You can also see EL Morro on a sunset cruise around the bay.

2- Visit Castillo de San Cristobal

The Castillo de San Cristobal is the largest European fortification in the Americas.

Construction on this part of the fort began in 1634 but wasn’t completed until 1790.

This fortification covers a whopping 27 acres at the easternmost gate of San Juan and was built to protect El Morro.

Castillo de San Cristobal is named after Saint Christopher, the patron saint of travelled lands.

The original fort encircled the whole of San Juan until the 19th century when part of it was destroyed to make way for the city’s expansion.

During World War II, Castillo served as a U.S. military base; there was even an underground bunker that acted as a control centre. You may like this walking tour of Old San Juan.

3- Visit San Juan de la Cruz

San Juan de la Cruz is in Isla de Cabras across from El Morro and functioned together with El Morro to protect the bay.

You might also notice that this fortification is called El Cañuelo.

The sandstone walls of this fort date back to 1630. It even survived an 1898 bombardment by the U.S. Navy.

This is the smallest fort that protects the San Juan harbour.

3- Join A Ranger-Led Program
