The Mattituck Historical Society operates a historic complex on the
south side of Main Road (Route 25), about half a mile east of Mattituck
High School, which includes the main museum house, an 1864 schoolhouse, a
milk house and a barn. The white Georgian home, now a museum, was built
in 1800, and its large west wing added in 1841. It is furnished with
antiques of the period, and displays a collection of toys and rare
musical instruments. Other displays include century-old clothing, guns,
quilts, maps and arrowheads.
