Mansion Farm, also known as Mansion House Farm, was part of George Washington's Mount Vernon. George Washington subdivided Mount Vernon into create discrete working units and a structured land management system. These units included the Mansion Farm, the Ferry Farm, French's (named for the former owner), Dogue Run, Muddy Hole, and River Farm. Additionally, there was a grist mill and land holdings that comprised the mill race, meadows, and a dam and pond on Dogue Run.
The Mansion House Farm was not a farm in the typical sense of the word—no large-scale cultivation of field crops was carried out on or around the house. Rather, the 500 acres directly around the mansion were developed as a gentleman's country seat, a new-world version of an English country house of the period. Located within a deep border of woods were rolling meadows, vistas, and groves of trees.
