The New Castle Historical Society’s newest exhibit opens Tuesday at the Horace Greeley House, 100 King Street, in Chappaqua.

The exhibit, titled “New Castle’s Beginnings – Our Founding Farms” traces the town’s origins from Native American lands to the farms of the 19th century to the large estates and housing developments that define the community today. The society will also focus on several local farms and feature their products, among them: Sutton Farm, Dodge Farm, Brann Farm, Taylor and Annandale Farms and the Greeley Farm.

There will be interactive aspects to this exhibit plus a seminar series featuring speakers from local farms operating today.

The historical society will hold an opening reception on Sunday, March 3, from 3 p.m. to 5 p.m. The exhibit will run through the year at the Horace Greeley House. The facility’s hours are Tuesday, Wednesday, Thursday and Saturday from 1 to 4 p.m. or by appointment at 914-238-4666.
