Henry Pratt purchased the Lemon Hill Estate from Robert Morris in 1799 and built the present house in 1800. He named it Lemon Hill after the famous lemon trees in the Morris greenhouse. Lemon Hill was built in the Neoclassical style, reflecting Pratt’s desire to turn the house and grounds into an impressive showplace. The furnishings of Lemon Hill include a number of important examples from the collections of the Philadelphia Museum of Art and represent the talents of a number of Philadelphia craftsmen working in the Neoclassical style during the period of Pratt's occupancy. Lemon Hill was the first Fairmount Park House to be purchased by the City. Since 1957, Lemon Hill has been administered by the Colonial Dames of America, Chapter II, a nonprofit patriotic society.
