Built in 1759 on Brattle Street in Cambridge, this mid-Georgian house links the American Revolution and nineteenth-century literary life. Originally the summer home of Loyalist John Vassall Jr., it was seized during the Revolution, briefly used as a hospital and barracks, and then served as George Washington's headquarters during the Siege of Boston, where he led the early Continental Army and received important visitors. After passing through several owners, it became the home of Henry Wadsworth Longfellow, who lived and wrote here for nearly fifty years. Preserved by his family, it endures as a rare place where political, military, domestic, and literary history meet.
