Washington Slept Here — Provably
Summerseat
The mansion where Washington planned in the dark December of 1776 — later owned by two signers of the Declaration and the Constitution.
Summerseat is one of the most credentialed historic houses in Pennsylvania: the handsome Georgian mansion on the hill above Morrisville served as George Washington's headquarters for a critical week in December 1776, in the desperate days before the Delaware crossing and the strike at Trenton. Few "Washington slept here" claims survive scrutiny; this one is documented.
The house's later owners doubled its distinction — Robert Morris, financier of the Revolution and the borough's namesake, and George Clymer, like Morris a signer of both the Declaration of Independence and the Constitution. Preserved by the Historic Morrisville Society, Summerseat opens for tours and events as the borough's proudest room.
History & Heritage
December 1776
Washington made his headquarters at Summerseat from December 8 to 14, 1776, as the Continental Army — beaten across New Jersey — regrouped on the Pennsylvania shore. From this house he corresponded, planned, and held the army together in the campaign's darkest stretch, days before the Christmas crossing changed the war.
Standing in the rooms where those letters were written, with Trenton visible across the river they would cross, gives the story a immediacy no textbook manages.
History & Heritage
Morris, Clymer, and the house's second act
After the war, Summerseat passed through the hands of Robert Morris — the Revolution's financier, for whom Morrisville is named — and then George Clymer, making it a residence of two of the six men who signed both the Declaration of Independence and the Constitution.
The Historic Morrisville Society maintains the mansion today, opening it for tours, school visits, and community events that keep the borough's founding credentials in active use.
