Overview
Dey Mansion Washington's Headquarters is one of New Jersey's most significant Revolutionary War landmarks. Built in the 1770s by Colonel Theunis Dey, the mansion served as General George Washington's headquarters on multiple occasions during 1780 as he directed Continental Army operations from northern New Jersey. The location was selected because of its strategic position, access to supplies, and proximity to important military routes. During Washington's stay, many of the war's most influential military leaders and advisors passed through the mansion, including Alexander Hamilton, the Marquis de Lafayette, and other prominent figures who helped shape the American Revolution.
Today, the beautifully restored Georgian-style home allows visitors to step back into the eighteenth century through guided tours, period furnishings, exhibits, and educational programs. The mansion interprets both the life of the Dey family and the military activities conducted from the headquarters during the Revolutionary War. Surrounding grounds, gardens, and exhibits help illustrate colonial life in New Jersey while highlighting the strategic importance of the region during the struggle for independence. For travelers interested in Revolutionary War history, the site offers an immersive look at one of Washington's most important headquarters and the people who contributed to the founding of the United States.
