Points of Interest

Mt. Harmon Front ViewPlantation House

The manor house is a three-story, five-bay, brick double pile structure which restoration architect Albert Kruse dated to 1730. The house is listed by the National Register of Historic Places. The manor house has been restored to the 1760 – 1810 period and is furnished with American, English, Irish and Scottish antiques, to reflect Mount Harmon’s owners of that period, who actively traded with the British Isles. The Chinese Chippendale staircase and elegant furnishings reflect the refinement of plantation culture in early America.


The plantation kitchen recalls domestic life and work on a colonial American plantation. It stands apart from the manor house and was restored and furnished with authentic kitchen artifacts of the colonial era

Prize House

Prize HouseMount Harmon was not only a successful tobacco plantation, but a local center for tobacco shipment for the Sassafras area. It boasts the northernmost existing tobacco prize house. “Prize” refers to the huge wooden screw used to compress tobacco from two casks into one for more efficient shipment.

Discovery CenterEducation & Discovery Center

Housed in the renovated plantation stables, the Education & Discovery Center features a Mount Harmon Highlights in History Exhibit, expanded educational programs, and is available for special and community events.

Serpentine WallGardens

The formal boxwood garden enclosed by serpentine brick walls evokes Mount Harmon’s golden age. Between the boxwood garden and the manor house are a pair of magnificent English Yew trees (Taxus baccata, variety dovastonii). These 200-year-old yews may be the oldest in the United States.

Nature Trails

A network of nature trails provides easy access to the plantation’s pristine natural surroundings – a historic Tidewater landscape, little changed by time. The trails allow visitors to explore the plantation’s scenic waterfront, rare tobacco prize house, and diverse ecosystems full of wildlife.


Wildlife is abundant at Mount Harmon. The entire plantation is a nature preserve, and all forms of plants and animals on the property are protected. Visitors are requested not to pick the flowers or otherwise disturb plants and animals.

EagleRare and Endangered Species

Several rare and formerly endangered species live at Mount Harmon. A pair of American bald eagles nests in the vicinity and can be seen hunting over the plantation. The American Lotus (Nelumbo lutea), a relative of the water lily and the largest wildflower in the United States, is rare in Maryland and neighboring states but abundant at Mount Harmon with its peak flowering in August.
