San Jerónimo Fort Free Tour

The Puerto Rican island of San Juan still houses vestiges from the colonial era, such as the Fort of San Jerónimo del Boquerón, where we'll meet at 9:30 am ready to learn all about the history of this 18th century fortress.

During this 45-minute guided tour, we'll visit the weapons room, the chapel, the kitchen and the cannon battery-towers, used to defend San Juan from foreign invasion. In the 16th century, English corsairs like Francis Drake and George Clifford tried to attack the island of Puerto Rico and other areas of the Caribbean.

As we explore the fort, we'll discover how it links to other colonial defensive monuments on the island of San Juan, such as the the Escambrón Fort, the Castle of San Cristóbal and the Castle of San Felipe del Morro. What's more, we'll find out about the different projects to restore the San Jerónimo Fort, which was declared a Historic Site in 1983. 

The free tour will end at 10:15 am at the main entrance to the fort.
