What was the first Philadelphia building to be built higher than the statue of William Penn on top of City Hall?
The “gentlemen’s agreement” kept all of Philadelphia’s buildings lower than the top of Alexander Milne Calder’s statue of Penn on top of City Hall. However, in the 1980s the “gentlemen’s agreement” was broken with the construction of the LibertyPlacePlazaby Chicago’s Helmut Jahn.
