From Colonial Outpost to Corporate Enclave

North Castle's story begins long before its formal incorporation. The area was inhabited by the Siwanoy people of the Lenape nation before European colonists — many arriving from Massachusetts, Connecticut, and Quaker communities in Rye and Long Island — began establishing farms in the early 1700s. The town held its first official meeting on April 6, 1736, and was formally incorporated on March 7, 1788, before being divided in 1791 to create the adjacent Town of New Castle.

During the Revolutionary War, North Castle occupied a strategically critical position in Westchester County's contested neutral ground. The Battle of White Plains in October 1776 saw Washington's Continental Army fortify Chatterton Hill against Hessian forces under General Howe. The Elijah Miller House served as a temporary headquarters for Washington himself — a structure later added to the National Register of Historic Places in 1976. In September 1780, British spy Major John André was detained at Wright's Mill here before his transfer to trial in Tappan, cementing the town's place in the drama of the Revolution.

Through the 19th century, agriculture and shoemaking defined the local economy. The early 20th century brought a quieter transformation, as affluent New Yorkers discovered the rolling terrain and began establishing country estates — a pattern that laid the groundwork for today's upscale residential character. The pivotal modern turning point came in 1964, when IBM established its global headquarters in Armonk, anchoring a corporate identity that continues to shape the town. That legacy is directly visible in today's real estate north castle ny market, where a median home price exceeding $1 million reflects centuries of careful, deliberate development rather than speculative sprawl.
