Harmony Hall under renovation
Harmony Hall Mansion was built in 1769 by tobacco merchant Enoch Magruder. After passing through many owners, the house was sold to the National Park Service in 1966…and there it has sat for fifty years, still not open to the public. Nothing prevents you from parking in the driveway near the road (the driveway is chained off) and walking down to take a look, but until the mansion is open one day, there really is no point in stopping by. There is no information on the National Park Service’s Harmony Hall site about if and when the building will ever open.
Also on the 62-acre property is a barn and the ruins of another home, Want Water. The barn appears to be a more modern structure, while Want Water, of which only two outer walls remain, is one of the oldest structures in Prince George’s County. There is also a canal on the property that still exists. It is thought to be the oldest man-made canal in the United States.
