U.S. Steel Tower in Pittsburgh

U.S. Steel Tower is the tallest skyscraper in Pittsburgh, Pennsylvania and the 33rd tallest in the United States. When completed in 1970, the tower stretched 64 floors to 841 ft (256 m). Its original name was the U.S. Steel Building for many years before it was changed to USX Tower. The name was finally changed to the U.S. Steel Tower in January of 2002 to reflect U.S. Steel's separation from its parent company and to recognize U.S. Steel as the largest tenant of the building (occupying more than a half million square feet (50,000 m²) of office space)

In the initial planning stages of the building, the U.S. Steel Corporation considered making the building the world's tallest although eventually settled on 840 feet (256 m). At 840 feet (256 m) when built, it became the tallest building outside of New York City and Chicago.

The tower is architecturally famous for its triangular shape with indented corners. The building also made history by being the first to use liquid-fireproofed columns.

U.S. Steel Tower makes an appearance in the movie Dogma, serving as the headquarters for the fictitious fast-food franchise "Mooby".

The building's official address is 600 Grant Street, Pittsburgh, PA 15219
