West Windsor Township was incorporated in 1797 encompassing seven hamlets: Port Mercer, Penn's Neck, Clarksville, Princeton Junction/Berrien City, Grover's Mill, Dutch Neck and Edinburg. By the 1800's, this prosperous farming community was prized for its central location between New York and Philadelphia. Today, West Windsor is a major center for research, retail, and corporate offices with a population of approximately 21,500 residents within its 27 square miles.
