Dey Mansion

The Dey Mansion is a colonial residence built during the 1770s in New Jersey, displaying Georgian-style architecture blended with Dutch and English design elements. The structure preserves its original layout and maintains period details throughout the rooms and exterior that reflect construction methods and tastes from that era.

The house was built in the late 1760s by Henry Dey and gained importance during the American Revolution. General George Washington used it twice in 1780 as a military headquarters to direct operations against British forces.

The rooms display furnishings from the colonial period and feature an original summer kitchen that shows how household life operated during the Revolutionary era. Walking through these spaces reveals the daily routines and domestic arrangements of a wealthy family from that time.

The house opens for visitors on specific days when guided tours are available to show the rooms and explain their significance. Good pathways lead to the building, and it helps to check ahead for the days and hours when you can visit.

Two prominent French military leaders, including the Marquis de Lafayette, met here with Washington to discuss war strategies. These encounters show how important this location was for coordinating the French-American alliance during the conflict.
