William Penn is a bronze statue of William Penn, the founder of the Commonwealth of Pennsylvania, by Alexander Milne Calder.

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.

[citation needed] The statue is facing northeast towards Penn Treaty Park.

The decision was made by the city's Public Buildings Commission over the objections of Calder who wanted it facing south to take advantage of the southern exposure.
