This is the final resting place of more colonial and Revolutionary War leaders—including Ben Franklin and four other signers of the Declaration of Independence—than any other nonmilitary cemetery in the country. As a nod to Franklin's proverb "a penny saved is a penny earned," you'll find his grave strewn with pennies that people have tossed there for good luck. Open Monday-Saturday 10 am-4 pm, Sunday noon-4 pm (weather permitting). Guided 35-minute tours are available. US$2 adults, includes tour. Arch Street (between Fourth and Fifth streets), Philadelphia.
