This is the largest of the bastions, originally built to protect the Puerta de Mar, a sea gate that was one of four original entrances to the city. Because it uses no supporting walls, it resembles a Roman triumphal arch. It has comparatively complete parapets and embrasures that offer views of the cathedral, municipal buildings, and old houses along Calle 8. Inside is the Museo de Arqueología Maya, with artifacts that include a well-preserved sculpture
of a man wearing an owl mask, columns from Edzná and Isla de Jaina, and at least a dozen well-proportioned Mayan stelae from ruins throughout Campeche.
Calle 8, between Calles 55 and 57, Campeche City, Campeche, 24000, Mexico
