The Mansion is built in the Palladian style, with a second story balcony and a two-story front portico supported by classical columns. The two-story octagon at the rear of the house is believed to be the first of its kind anywhere in the colonies.
The first floor of the 8,500 square foot house features rooms for family and social gatherings, and includes the parlor in which Madame Eliza Jumel married Aaron Burr in 1833. Across the hall stands the dining room where Washington likely entertained his guests in 1790. At the far end of the hall, the octagonal drawing room, or withdrawing room as it is properly known, provided a grand setting for social gatherings. Bedrooms on the second floor include those of George Washington, Eliza Jumel, and Aaron Burr. The basement houses the colonial-era kitchen and tells the story of domestic servitude at the Mansion. The room features the original hearth and a bee-hive oven as well as a collection of early American cooking utensils.
Through architecture and a diverse collection of decorative arts objects, each room of the Morris-Jumel Mansion reveals a specific aspect of its colorful history from the 18th through the 19th centuries.
