The Cubo Line

Following the 1702 English siege of St. Augustine, the Spanish began construction of a defensive system to protect the Presidio. Built in 1704 to safeguard the town's northern sector, the Cubo Line was the first line of defense the Spanish raised. In the early 18th century, the Spanish in Florida used the medieval term Cubo to describe rounded, pointed or square bastions built into defensive walls, and the Cubo Line took its name from three cubos built into its wall. Throughout the 18th and early 19th centuries, the Spanish in Florida applied the term reducto, or redoubt, to cubos built into defensive walls.
