The alleged curse of Billy Penn was sometimes used to explain the failure of professional sports teams based in Philadelphia to win championships.
In March 1987, One Liberty Place, a 945-foot (288 m) tall skyscraper, opened three blocks from the 548 ft (167 m) high statue of William Penn atop Philadelphia City Hall.
For many decades, a gentlemen's agreement stated that the Philadelphia Art Commission would approve no building in the city that would rise above this statue.
The supposed curse had gained such prominence in Philadelphia that a documentary film entitled The Curse of William Penn was produced about it.

The curse ended on October 29, 2008 when the Phillies won the World Series, a year and four months after a statuette of the William Penn figure atop City Hall was affixed to the final beam put in place during the June 2007 topping-off of the Comcast Center, then the tallest building in the city.
