Historical Foundations
The origins of West Windsor date back to the 17th century. The area was originally part of Piscataway Township when it was chartered on December 18, 1666, before the formation of Middlesex County in 1683. The modern township structure began to take shape in the late 18th century.
By an act of the New Jersey Legislature on February 9, 1797, West Windsor and its neighbor, East Windsor, were established by partitioning the provincial Windsor Township. They were formally incorporated on February 21, 1798, as part of the state's first group of 104 townships.

Preserving this legacy is the Historical Society of West Windsor, headquartered at the c. 1790 Schenck Farmstead, which serves as the local history museum.
