Dey Mansion Guided Tour

Book Your Guided Tour of Dey Mansion, Washington's Headquarters 1780
Dey Mansion is ready to welcome you to George Washington's 1780 headquarters site as we celebrate America's 250th birthday in 2026!

Join us on a guided 60- to 90-minute tour to explore Dey Mansion's history and learn about Washington's time here. The guided tour includes visits to the Mansion and the outbuildings. Additionally, we encourage guests to meet in the Visitor Center before their tour to learn about the site and see our collection of objects on display that relate to the history of the Dey family and the Revolutionary War.

Tours are offered Wednesday through Sunday, 10:00 AM to 5:00 PM. (The last tour starts at 4:00 PM, and the overall site closes 5:00 PM.)

Things to Know Before Your Visit

• All tours are guided; guests explore Dey Mansion accompanied by a knowledgeable tour guide throughout your visit.
• The first floor of the mansion and the grounds are ADA accessible.
• Pets and animals are not permitted on tours, with the exception of certified service animals as defined under the Americans with Disabilities Act (ADA). Animals whose sole function is to provide comfort or emotional support do not qualify as Service Animals under ADA and are, therefore, not permitted.
