Mount Harmon Plantation is the northernmost colonial era Tidewater plantation open to the public, and is a scenic and historic treasure.

In cooperation with Washington College, Chestertown, MD Mount Harmon is in the planning stages of an archaeological dig.

The plantation is situated on a peninsula formed by creeks and inlets of the Sassafras River in Cecil County, Maryland, known on early maps as World’s End. Mount Harmon is listed on the National Historic Register, is an official Chesapeake Bay Gateway Network site, and is located along the National Scenic Byway.


Mount Harmon is administered by Friends of Mount Harmon, Inc., a non profit organization dedicated to the preservation and interpretation of Mount Harmon, for the public’s education and enjoyment.


Mount Harmon Plantation began as a land grant in 1651. In 1963 Marguerite du Pont de Villiers Boden, in tribute to her ancestors rescued this tobacco plantation, its tobacco prize house, and its manor house, which she completely restored and furnished as an 18th century mansion. It is now open to the public as a historic site and nature preserve.
