Pennington was established as a Borough by an Act of the New Jersey Legislature on January 31, 1890.  We are located in beautiful Central New Jersey and Pennington Hopewell Valley Historical Society Logo'proper' has a total of 1.0 square mile, all of it land.  We are an independent municipality surrounded by Hopewell Township

Being a proud part of Hopewell Valley, and the Township, Pennington Residents may enjoy viewing the Hopewell Valley Historical Society link.  The Society does much to preserve our unique identity. 

If you choose, you may contact the Borough of Pennington directly throughPhoto of Main Street Circa 1800 this link.  We share the Pennington Borough facility, so if you stop by the Library, you can just drop in to the Pennington Borough Hall.
