One Liberty Place
One Liberty Place at Night
The One Liberty Place Building is the tallest building in Philadelphia and the 16th tallest building in the United States. One Liberty Place is 61 floors or 945ft (288m) and is only two feet smaller than Key Tower in Cleveland, Ohio.
Completed in 1987, One Liberty Place was locally famous for being the first building to break the gentlemen's agreement which was not to exceed the 548ft (167m) height of the William Penn statue on Philadelphia City Hall built in 1901. Since One Liberty Place's completion over seven other skyscrapers have been built exceeding the statue's height.
After One Liberty Place's completion, a slightly smaller sister building known as Two Liberty Place (shown behind One Liberty Place in the picture) was built in 1990 at the same Liberty Place Complex. Two Liberty Place is only 58 stories and 848ft (285m).
The One Liberty Place Building has some of the newest technology available such as a modern exterior ice and snow melting system and a chilled water plant equipped with cooling towers, pumps, and chillers.
On October 12, 1999, One Liberty Place was sold to Philadelphia Liberty Property, L.P for $185 million and an additional $28.2 million for the land.
CIGNA, a large insurance corporation in the United States, has its headquarters in this building.
