The Headquarters of George Washington is a historic log cabin in Cumberland, Maryland that was built for then Colonel George Washington for his use between 1755 and 1758 during the French and Indian War. He also used it briefly during 1794 as Commander in Chief in order to review the troops gathered to put down the Whiskey Rebellion.
The headquarters historical marker claims the headquarters "antedate all similar headquarters in the United States".
The headquarters was part of Fort Cumberland during the French and Indian War. It was built by General Edward Braddock's men for Washington. It is the only building to survive from the Fort, and has been moved to Riverside Park.
