In 1781, the British under General Cornwallis surrendered at Yorktown after a siege of three weeks by American and French troops; the surrender ended the American Revolution. When we visited Yorktown, it was known as the Yorktown Victory Center with a visitor's center, 1780s farm, galleries, and the Continental Army encampment. It has since been revamped and renamed the American Revolution Museum of Yorktown.
Yorktown was one of those sites that offered a great homeschool program and we really enjoyed our visit. It's back on the Places to Visit list so that we can see the updated museum.
