The 18th century Harmony Hall mansion stands on a 62.5-acre estate of open pasture land along the Potomac River. The National Park Service purchased the estate in 1966 to preserve southern Maryland cultural heritage. Surrounded by a rich landscape, it offers many chances to connect with Colonial history. The park is also home to the remains of the Want Water House and canal. Summers are generally hot and humid, with daytime highs frequently above 90 degrees Fahrenheit and scattered afternoon thunderstorms. Winters are generally cold, with nighttime lows frequently near freezing and occasional snowfall. Weather during spring and fall is generally moderate, but can change quickly.
