Overview
Fort Frederick State Park on the Potomac protects the largest stone fort ever built in Maryland, built in 1756 during the French and Indian War and one of the best-preserved 18th-century forts in North America. Its thick limestone walls, barracks, bastions, and exhibits interpret military life in the French and Indian War and the Revolution, and living-history events, reenactments, and costumed interpreters run through the year. The 500-plus-acre park borders the C&O Canal towpath.
