Litchfield Villa, unknown date.

This stucco mansion, located just inside the entrance at Prospect Park West and 5th Street, was built for Edwin C. Litchfield between 1855 and 1857. A prominent Brooklyn real estate developer and landowner in present-day Park Slope, Litchfield was responsible for the expansion of the Gowanus Canal from a tidal creek into a shipping channel.

In 1855, Litchfield hired acclaimed architect Alexander Jackson Davis to construct an Italianate estate for his family. In addition to the hilltop mansion, Davis also built a coach house, greenhouse, and chicken house (none of which remain today). When completed in 1857, the structure was named Grace Hill, after Edwin's wife Grace Hill Hubbard Litchfield.

In 1869, the Litchfields reluctantly ceded their home and its grounds to the City of Brooklyn, but were granted permission to lease the property until 1883. Those 50 acres of Litchfield land now constitute over five percent of the park's present acreage.

In 1882, Litchfield's Brooklyn Improvement Company — the firm that oversaw the Gowanus Canal project — moved into the former NY & LI Coignet Stone Company building at Third Avenue and 3rd Street (adjacent to the present-day Whole Foods).

In 1883, a year after Grace Litchfield's death, Edwin Litchfield moved abroad and his villa was passed on to the City Park Commissioners. The Litchfield Villa, as it is now known, is now the Brooklyn borough headquarters of the NYC Department of Parks and Recreation and also the home of the Prospect Park Alliance.
