Thornwood is a hamlet inside the town of Mount Pleasant and is about a 40-minute drive north from Manhattan. This region was originally inhabited by Algonquin Lenape Native Americans. The Harlem Line of the Metro-North Railroad established a station in Thornwood, but it was eliminated in the mid-1980s due to electrification. The area was, at one point of time, home to a large and flourishing marble quarry. In the 1980s, this quarry pit was filled up and a shopping center was built over it. Thornwood is currently an unincorporated hamlet in Westchester County.
