The Dey Mansion, built around 1770, was home to Theunis and Hester Dey before playing a vital role in the American Revolution as General George Washington’s headquarters in 1780. A distinguished family with deep colonial roots, the Deys contributed to public life, with Theunis serving in the State Council and as a trustee of Queen’s College (now Rutgers University). Washington first arrived in July, overseeing an attack on Bull’s Ferry before departing to coordinate with French allies. He returned in October amid the turmoil of Benedict Arnold’s treason, using the mansion’s strategic location in the Preakness Valley to safeguard his forces.

During Washington’s stay, military efforts included a planned attack on Staten Island and reconnaissance near Fort Lee, though some operations were ultimately called off. On November 27, 1780, he departed for Morristown, leaving behind a legacy that remains preserved in the mansion’s walls. As one of Washington’s surviving field headquarters, the Dey Mansion continues to offer visitors a glimpse into the challenges and triumphs of the Revolutionary War.
