Built between 1667 and 1680, Timothy Knapp's house is thought to be the oldest house in Westchester County. It initially had just two rooms: a keeping room with a bedchamber above. Knapp farmed the land and served as the town constable and tax collector, and he was also a vestryman for Grace Church, now Christ's Church, where services were held before the first church was built in 1705. Ezekiel Halsted, a wealthy landowner, purchased the house in 1749 and expanded it twice. During his family's 150 years of ownership, the house acquired its distinctive saltbox shape and fish scale shingles. After converting to Methodism in the early 1800s, the Halsteds also held religious services there. In 1906, Simeon and July Ford, summer residents of a 48-room cottage on Forest Avenue, bought the house for their children. The Fords added a studio for their daughter Lauren, a successful artist, but otherwise the house was largely unchanged. Today it is listed on the State and National Registers of Historic Places, is owned by the Rye Historical Society, and houses Rye's archives.
