Discover Cranbury's Past
Cranbury has a long and interesting history. The first buildings were likely built around 1698.
Cranbury's Role in the American Revolution
During the American Revolutionary War, a home in Cranbury was used by Alexander Hamilton and the Marquis de Lafayette as a headquarters. General George Washington visited them on June 26, 1778. During this visit, Washington planned how to stop the British army as they retreated from Philadelphia to New York City. This plan led to the important Battle of Monmouth, which happened nearby.
After the war, maps of Cranbury made during George Washington's time showed a church, a mill, and 25 other buildings.
How Cranbury Got Its Name
In its early days, the area was often called "Cranberry." In 1857, a reverend named Joseph G. Symmes suggested changing the name to "Cranbury." This change happened in 1869. The name comes from the wild cranberries that used to grow in the area.
Important Events and Growth
Cranbury became an official township on March 7, 1872. This happened when parts of Monroe Township and South Brunswick Township joined together. Later, in 1919, Plainsboro Township was formed from parts of Cranbury.
In 1998, Cranbury celebrated its 300th anniversary! Historic buildings, like the Updike Parsonage Barn from 1759, have been moved and rebuilt to preserve them. In 2019, the Cranbury Historical and Preservation Society saved another old building, the 1713 East Jersey Cottage, from being torn down. They moved it to a new location to keep its history alive.
