Tallest skyscraper in Pittsburgh

Pittsburgh, the second-largest city in the U.S. state of Pennsylvania, is home to 137 completed high-rises, 29 of which stand at least 300 feet (91 m) tall. The tallest building in Pittsburgh is the 64-story U.S. Steel Tower, which rises 841 feet (256 m) and was completed in 1970. It also stands as the fourth-tallest building in Pennsylvania and the 43rd-tallest building in the United States. The second-tallest skyscraper in the city is BNY Mellon Center, which rises 725 feet (221 m).

The history of skyscrapers in Pittsburgh began with the 1895 completion of the Carnegie Building; this structure, rising 13 floors, was the first steel-framed skyscraper to be constructed in the city. It never held the title of tallest structure in the city, however, as it did not surpass the 249-foot (76 m) tower of the Allegheny County Courthouse, which was completed in 1888. The Carnegie Building was later demolished in 1952 to make way for an expansion of a Kaufmann's (now Macy's) department store. Pittsburgh experienced a large building boom from the late 1960s to the late 1980s. During this time, 12 of the city's 21 tallest buildings were constructed, including the city's three tallest structures, the U.S. Steel Tower, BNY Mellon Center, and PPG Place. The city is the site of 10 skyscrapers at least 492 feet (150 m) in height, of which two rank among the tallest in the United States. As of 2014^[update], the skyline of Pittsburgh is ranked 18th in the United States and 77th in the world with 25 buildings rising at least 330 feet (100 m) in height.
