The Castle of San Fernando de Bocachica is a horseshoe-shaped military fortress whose construction, directed by the engineer Antonio de Arévalo, began in 1753 on the ruins of the Castle of San Luis de Bocachica, which had been destroyed by the troops British during the siege to Cartagena Colombia in 1741.

The Castle of San Fernando de Bocachica was then built by the Spaniards during the colonial era in what is now Colombia. Located on Tierra Bomba Island, it controlled the entrance to the Bocachica channel.

This strength, also served as a prison because of its difficult access and the great protection it offered.

Nowadays Bocachica is currently a fishing village that has several beaches, typical restaurants and souvenirs which are available for visitors.
