History of West Windsor
Before Europeans settled here around the 1700s, the Lenape Native Americans lived in the West Windsor area. The Assanhicans, a Lenape group, lived in the wider Trenton area. You can still find artifacts from their time in West Windsor.
In 1634, an English captain named Thomas Yong explored the Delaware River. He reached the Trenton area, but it's not known who the first European was to step foot in West Windsor.
The area was part of Piscataway Township when it was first set up in 1666. This changed when Middlesex County was formed in 1683.
The original Windsor Township, which West Windsor came from, was officially created in 1751. It included what is now West Windsor, East Windsor, Hightstown, and Robbinsville. In 1756, The College of New Jersey moved to Princeton. When West Windsor was created in 1797, its borders reached Nassau Street. Later, in the 1800s, its borders changed again to what they are today.
For a long time, West Windsor was mostly a farming community. Farmers grew crops like wheat, tomatoes, rye, and potatoes. This continued until the late 1900s, when the township started to grow very quickly.
West Windsor never had one main "downtown" area. Instead, it had several small villages or hamlets. Some of these names are still used today:
- Aqueduct Mills
- Canal/Princeton Basin
- Clarksville
- Dutch Neck
- Edinburg
- Grovers Mill
- Penns Neck
- Port Windsor/Mercer
- Princeton Junction
Grover's Mill in West Windsor became famous in 1938. This was the spot Orson Welles chose for the Martian invasion in his famous radio show, The War of the Worlds.
In the late 20th century, West Windsor changed a lot. Many new homes were built, and the population grew quickly. By 1999, it had become a place with many expensive houses in planned communities.
In April 2002, a special memorial was built. It honors the seven residents of West Windsor who passed away in the September 11 terrorist attacks.
In 2019, the Historical Society of West Windsor created an online museum. It shares the history of the township.
