Editing Philadelphia City Hall (section)

== Height and Dimensions ==

Philadelphia City Hall stands '''548 feet (167 meters)''' tall from ground level to the top of the William Penn statue. The building itself rises 337 feet to the base of the tower, with the tower extending an additional 174 feet, plus the 37-foot statue.

At completion in 1901, Philadelphia City Hall was the tallest habitable building in the world—a title it held until 1908 when the Singer Building in New York City surpassed it. It remained the tallest building in Philadelphia until 1987 and the tallest in Pennsylvania until 1932 when Pittsburgh's Gulf Tower exceeded its height.
