Though it has many names -- the Steel Building, UPMC Building, USX Tower -- the U.S. Steel Tower is the undisputed champion of the title of tallest building in Pittsburgh. It also holds another impressive architectural title as the tallest building in the world with a completely flat roof: it was even used as a helipad. With its dedication in 1971, the building has gone through numerous name changes to reflect the changing business of U.S. Steel.
When initially designing the building, architects had lofty plans of trying to make it the world's tallest building, but decided on giving it merely the distinction of tallest building outside of New York and Chicago. By now it has lost the title, but it still stands as a testament to the growth and influence of U.S. Steel on the city.
Designed by Harrison, Abramovitz & Abbe, the building boasts 64 floors and a first-of-its-kind fire prevention structure, with 18 columns filled with a half a million gallons of water and antifreeze. Ultimately, the tower is well-known for its triangular shape, attempting to mirror the shape of downtown Pittsburgh.
On sunny days in Pittsburgh, the towering building can be seen from as far away as 50 miles. Explore the views of Pittsburgh below!
