Dyckman Farmhouse Museum

The Dyckman House, now the Dyckman Farmhouse Museum, is the oldest remaining farmhouse on Manhattan island, a vestige of New York City's rural past. The Dutch Colonial-style farmhouse was built by William Dyckman, c.1785, and was originally part of over 250 acres of farmland owned by the family. It is now located in a small park at the corner of Broadway and 204th Street in Inwood, Manhattan.
