Summerseat

Summerseat is a stone colonial mansion with two and a half stories, symmetrical proportions, and five bays arranged around a central entrance. The structure features a peaked gable on its east side that gives the building a formal and balanced appearance.

George Washington used the house as his headquarters in December 1776 to plan the strategic attack on Hessian forces in Trenton. The building thus served as a place of military importance during a critical phase of the Revolutionary War.

The house served as home to two men who signed both the Declaration of Independence and the Constitution: Robert Morris and George Clymer. This connection makes the place a key landmark in the nation's founding story.

The house is open to visitors but requires some planning due to limited hours of access. It helps to check in advance when tours are offered and whether registration is needed.

The dining room hosted a military court in 1781 that convicted two British spies. This event shows that the place served not only as a planning center but also as a site directly involved in espionage and intelligence operations during the war.
