The 18th century Harmony Hall mansion is located on a 62.5-acre open pasture land estate along the Potomac River in Prince George’s County, Maryland. This estate was purchased by the National Park Service in 1966, in hopes of preserving the decades of southern Maryland cultural heritage represented here. Built in the eighteenth century and surrounded by a rich landscape, it offers visitors many opportunities to learn about the area’s rich cultural and natural histories. Currently, the mansion and grounds are undergoing major repairs as the National Park Service works diligently to restore it to its original splendor.
