Kingston Mill Historic District, Historic district in Kingston, New Jersey, United States

The Kingston Mill Historic District covers 49 acres in Kingston, New Jersey, shared by Princeton, South Brunswick and Franklin Township. It holds 16 contributing buildings and 2 contributing structures, among them the 1888 Kingston Mill on the Millstone River, an 18th-century stone bridge, the Greenland-Brinson-Gulick farm and four neighbouring houses.

Henry Greenland, a tavern keeper from Piscataway, was granted 400 acres by deputy-governor Gawen Lawrie and built a tavern on the Millstone's west bank in 1683, likely the first European house in what is now Princeton. In January 1687 representatives of East and West Jersey met there to negotiate the colonial boundary survey. Greenland's grandson Barefoot Brinson built the area's first gristmill in the 1740s; after a fire during the Revolutionary War, John Gulick Jr. rebuilt the mill in 1797 and turned the adjacent road into a turnpike.

The mill served as Kingston's main commercial and social gathering place, where villagers met to talk and exchange goods. The district's name comes from this mill on the Millstone River. The surrounding houses and the 18th-century stone bridge survive alongside it.

The district straddles Princeton-Kingston Road where it crosses the Millstone River, and its territory is split among Princeton, South Brunswick and Franklin Township, so a visit crosses three municipal lines. The 18th-century stone Kingston Bridge carries the road over the river at the mill site. Greenland's tavern stood on the river's west bank.

The district's name comes from the mill that gave Kingston its main gathering place: villagers met there to talk and trade goods. The mill was burned by the British army in 1776 during the Revolutionary War and rebuilt in 1797 by stagecoach owner John Gulick Jr., who also turned the adjacent road into a turnpike.
