LUXURY PROPERTY AUCTION: 28 July-12 August. Accepting starting bids through 27 July. Listed for $20M. Earn an incentive by 27 July. Mulberry Fields is one of those rare places where the land itself tells the story. The mile-long cedar avenue announces the approach, its rows planted at an ever-widening angle to draw the eye toward the Potomac below, a feat of 18th-century landscape design so precise it has appeared in gardening textbooks for centuries. At the end of that drive stands the last surviving Georgian manor house in St. Mary's County, a ca. 1755 brick estate where the center hall, great room, and dining room are paneled in raised wood from floor to ceiling, the original moldings, doors, and mantels intact after nearly 270 years. Beyond the manor, two Georgian brick dependencies anchor a formal north courtyard, and the grounds unfold across just under 500 acres of fertile land before meeting 1,700 feet of white sand Potomac riverfront. There is simply no other property like this on the Eastern Seaboard.
