It is a military construction that allowed land access to the city to be defended from any angle.
The upper part of the enclosure has a defense system where the enemy was attacked if they gained access.
Above the door the remains of the guardhouse and the stairs that gave access to the roundabout survive. This is where the Calle 59 pedestrian tourist corridor begins and is a must-see building on your visit to Campeche.
