Summerseat, also known as the George Clymer House and Thomas Barclay House, is a historic house museum at Hillcrest and Legion Avenues in Morrisville, Bucks County, Pennsylvania. Built about 1765, it is the only house known to have been owned by two signers of the United States Declaration of Independence, Founding Fathers George Clymer and Robert Morris, and as a headquarters of General George Washington during the American Revolutionary War. The house is now managed by the Morrisville Historical Society, which offers tours. It was designated a National Historic Landmark in 1965.
