Since its initial construction in 1765, Summerseat has depended on citizens of Morrisville to protect and maintain the structure. Over 250 years later, the building still stands in its original location, encapsulating history and providing important context for local education.

Historic Summerseat is the site where George Washington planned the pivotal Battle of Trenton which occurred December 26, 1776. Summerseat 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.
