Mount Vernon re-creates a lively early-American marketplace with demonstrations, crafts and entertainment at its Colonial & Market Fair. Juried artisans from across the nation will demonstrate their trades and sell their wares while two stages of family entertainment delight audiences with 18th-century amusements such as Signora Bella the Equilibrist, Otto the Sword Swallower and more! Free Potomac River sightseeing cruises are available while supplies last. As visitors shop, artisans demonstrate their crafts and explain the historic trades used to make items similar to those George Washington purchased in the 18th century. Historical chocolate-making demonstrations will also take place. Revolutionary War re-enactors perform 18th-century military drills on the Bowling Green.
