Exploring Plainsboro's Past
The first people to live in the Plainsboro area were the Unami people. They were a group of Lenape Native Americans. In the 1600s, the Dutch settled here. They liked the area for its good farmland.
The oldest part of Plainsboro is where Dey Road and Plainsboro Road meet. It's believed that the road was named after an old Dutch tavern. This tavern, called "The Planes Tavern," was built there in the early 1700s. The building is still standing today.
Farms and Dairy History
In 1897, the Walker-Gordon Dairy Farm opened. This farm was very famous. It even contributed to the creation of Elsie the Cow, a well-known dairy mascot. The farm also had The Walker Gordon Diner, which is now closed. The land where the farm once stood is now a neighborhood with over 350 homes.
Other family farms, like the Parker, Simonson, Stults, and Groendyke farms, also came to Plainsboro. The Parker Farm and Groendyke farm became part of Walker-Gordon's Dairy Farm. Today, the Simonson and Stults Farms are still active in Plainsboro.
How Plainsboro Became a Township
Plainsboro was officially founded on May 6, 1919. It was created from parts of Cranbury and South Brunswick townships. This happened because Cranbury and South Brunswick wouldn't build a new, fireproof school in Plainsboro Village. Every year, this date is celebrated with a parade, festival, and concert.
In 1971, Princeton University and Lincoln Properties, Inc. began to develop the area. Princeton University owned most of the land in the township. They helped turn Plainsboro into the large suburban area it is today. Yet, it still keeps some of its rural charm.
By the 1980s, Princeton University owned nearly 5,000 acres (2,000 ha) in Plainsboro. This was much larger than their original university campus. To handle the growth, West Windsor-Plainsboro High School South opened in nearby Princeton Junction. Later, West Windsor-Plainsboro High School North opened in Plainsboro in September 2000. This created a friendly rivalry between the two schools.

Modern Plainsboro Developments
The newest addition to Plainsboro is the Village Center. It's next to the historic village area. The Village Center has many shops, offices, and homes. It features wide sidewalks, outdoor seating, and a large village green with a fountain.
The Village Center also has a new Plainsboro Library. It cost $12.4 million and opened on April 10, 2010. New buildings are also being built for medical offices, more shops, and homes.
A new hospital, now called Penn Medicine Princeton Medical Center, was built in Plainsboro. This hospital opened in May 2012. It replaced an older hospital that had been used for 93 years. The new hospital is a modern medical campus. It includes medical offices, an education center, and a health and fitness center.

Plainsboro Township covers about 12.11 square miles (31.37 km2). Most of this is land, with a small amount of water.
