Philadelphia is Pennsylvania’s largest city and most notable for its rich history, including the Liberty Bell, Independence Hall (where the Declaration of Independence and Constitution were signed) and other American Revolutionary sites. Also iconic are the steps of the Philadelphia Museum of Art, immortalized by Sylvester Stallone’s triumphant run in the film “Rocky.” If you’re into sports, you’re in the company of the Philadelphia Eagles, Philadelphia Flyers, Philadelphia Phillies and Philadelphia 76ers.
