Litchfield Villa, or "Grace Hill", is an Italianate mansion built in 1854–1857 on a large private estate now located in Prospect Park, Brooklyn, New York City. The villa was listed on the National Register of Historic Places in 1977.
Litchfield purchased the land in 1852, and the structure was built in 1854–1857 at a cost of $150,000. It predates the construction of Prospect Park, which opened in 1867. The original plans for the park called for it to be built around Litchfield Villa, since Litchfield was loath to sell his property. The New York City Parks Commission ultimately acquired the Litchfield plot in 1868 for $1.7 million, representing 42% of the overall land expenditure for the park, even though the plot constituted just over five percent of the park's acreage.
