Fort Mose Historic State Park The historic site of Fort Mose, established in 1738 by the Spanish as the northernmost point of defense of St. Augustine, is a landmark in American history.
Construction began on Fort McHenry in 1798 and, by 1803, the masonry walls we view today were completed. The fort was named for James McHenry, our second Secretary of War. In 1809, the U.S. Army's first light artillery unit was organized here.
