William Penn

William Penn is a bronze statue by Alexander Milne Calder of William Penn, the founder and namesake for the Commonwealth of Pennsylvania.It is located atop the Philadelphia City Hall in Philadelphia, Pennsylvania. It was installed in 1894. It was cast in fourteen sections, and took almost two years to finish.

For almost 90 years, an unwritten gentlemen's agreement forbade any building in the city from rising above the hat on the Penn statue. This agreement ended in 1985, when final approval was given to the Liberty Place complex. Its centerpieces are two skyscrapers, One Liberty Place and Two Liberty Place, which rose well above the height of Penn's hat.
