One of William Penn's five original squares, this seven-acre Old City park splits its playground by age so children under 5 get their own pint-sized zone. The surrounding square adds the Parx Liberty Carousel, Philly-themed mini golf, and a restored 1838 fountain with light shows, each with a nominal fee.
