Washington Square Philadelphia: A Storied Sanctuary
Washington Square – One of William Penn's five original squares has served as an animal pasture and as a burial ground—for victims of the 1793 yellow fever epidemic, African-Americans, and several thousand soldiers who died during the Revolution. The square is now famous for picnicking, reading, playing Frisbee, and other leisure activities. It's also the site of the Tomb of the Unknown Soldier of the American Revolution, a monument featuring an eternal flame and a statue of George Washington—6th & Walnut Street.
