Inscription. The small fort to your right, called San Juan de la Cruz, or El Canuelo, helped protect the entrance to San Juan Harbor. It is part of an extensive fortification system built by Spain over a 250-year period. The major surviving parts of these fortifications—which you can visit today—make up San Juan National Historic Site.
