From http://www.dnr.state.md.us/publiclands/western/fortfrederick.asp: American history from the colonial period to the present can be discovered at Fort Frederick State Park. Our 585 acre park features a unique stone fort that served as Maryland’s frontier defense during the French and Indian War. The Fort's stone wall and two barracks have been restored to their 1758 appearance. Historic exhibits are in the Fort, barracks, CCC Museum and Visitor Center. The park annually holds programs such as artillery firings, junior ranger, colonial children’s day and the 18th Century Market Fair. The park borders the Potomac River, and the Chesapeake and Ohio Canal passes through the park. The park also features a boat launch, campsites, camp store, fishing, flat water canoeing, a hiking trail, interpretive and educational programs, picnicking, a playground, and a shelter. For more information on facilities, hours, and programs please contact the visitor center. View the Fort Frederick State Park Calendar of Events for 2011.
