Philadelphia’s City Hall is the largest and tallest city hall in the US, and for locals, the midpoint for all things Center City. Designed by architect John McArthur, Jr., it was completed in 1901 and originally designed to be the world's tallest building, an honor that it held only briefly. There are over 250 ornamental marble statues decorating the exterior of the building, and it is topped off by a bronze statue of the city's founder, William Penn, created by sculptor Alexander Milne Calder. (Trivia: The statue is 37 feet tall and weighs 53,348 pounds, and once wore a super-sized Phillies baseball cap; then some years later was dressed in a giant Flyers jersey.)
Underneath the William Penn statue is a tower with an observation deck that offers incredible 360 degree views of the city (and the Schuylkill and Delaware Rivers, and New Jersey, and beyond!). This view, toward the southeast, captures the iconic PNB Building. Visitors can purchase timed tickets for the observation deck from the City Hall Visitor Center, Room 121 (east of the central courtyard).
