Historic Sites: Probably the most famous site in Philadelphia, Independence Hall is where Thomas Jefferson, John Adams, Benjamin Franklin and their rebellious compatriots approved and announced the Declaration of Independence. Built between 1732 and 1756, this notable building was also where George Washington was appointed commander-in-chief of the Continental Army, the design of the American flag was agreed upon and the U. S. Constitution was drafted. The restored structure is open year-round for tours.
Free Things to Do: Built between 1732 and 1756 as the State House of the Province of Pennsylvania, Independence Hall is one of Philly's most popular attractions. It's also free, and although tours are available year-round, timed tickets are needed from March through December. Beginning in the East Wing, tours take visitors through the building that served as the meeting place for the Second Continental Congress and the site where the Declaration of Independence was adopted in 1776.
