Dey Mansion Washington’s Headquarters

A visit to Dey Mansion offers a chance to step into the world of Colonial America. Once the home of Colonel Theunis Dey, the mansion served as General George Washington’s headquarters during the summer and fall of 1780 and played a meaningful role in the American Revolution. Walking through its rooms brings the era’s stories and decisions into clear focus.

Today, Dey Mansion welcomes visitors through guided tours, lectures, and special programs that explore daily life in the colonial period, pivotal moments of the Revolution, and the importance of preserving historic places.
