George Washington used this small log cabin (since covered with clapboard) as his office in 1755 and 1756 when he was a colonel in the Virginia militia, charged with building a fort to protect the colony's frontier from the French and the Indians. The building itself is the highlight of this charming little museum, whose exhibits explain Washington's career from 1748 to 1758. You can see it all in 30 minutes. Informative staff members are on hand to answer questions and lead guided tours.
