Longfellow National Historic House

The Longfellow House–Washington's Headquarters National Historic Site is a historic site located at 105 Brattle Street in Cambridge, Massachusetts. It was the home of noted American poet Henry Wadsworth Longfellow for almost 50 years, and it had previously served as the headquarters of General George Washington.

The house was built in 1759 for Jamaican plantation owner John Vassall Jr., who fled the Cambridge area at the beginning of the American Revolutionary War because of his loyalty to the king of England. George Washington occupied it as his headquarters beginning on July 16, 1775, and it served as his base of operations during the Siege of Boston until he moved out on April 4, 1776.
