context_page_description: Philadelphia, the largest city in the U.S. state of Pennsylvania, is home to more than 300 completed high-rise buildings up to 330 feet, and 56 completed skyscrapers of 330 feet or taller, of which 32 are 400 feet or taller and are listed below. As of 2019, the tallest building in the city is the 60-story Comcast Technology Center, which topped out at 1,121 feet in Center City on November 27, 2017 and was completed in 2018. Comcast Technology Center is the tallest building in the United States outside Manhattan and Chicago, and is currently ranked as the tenth-tallest building in the United States. The second-tallest building in Philadelphia is the 58-story Comcast Center at 974 feet, while the third-tallest building is One Liberty Place, which rises 61 floors and 945 feet. One Liberty Place stood as the tallest building in Pennsylvania for over 20 years until the completion of Comcast Center in 2008. Overall, seven of the ten tallest buildings in Pennsylvania are in Philadelphia, with the remainder being in Pittsburgh.
context_section_description: Philadelphia has seen few city record-holders compared to other cities with comparable skylines. Although churches, cathedrals, and the like are not technically considered to be skyscrapers, Christ Church, after being surmounted with its lofty spire in 1754, stood as its tallest building for 102 years before being surpassed by the (no longer extant) spire of Tenth Presbyterian Church, which was surpassed by City Hall in 1894. Then, due to the "gentlemen's agreement" not to build higher than the top of the statue of William Penn atop City Hall, that building stood as the city's tallest structure for 93 years; it also held the world record for tallest habitable building from 1894 until the 1908 completion of the Singer Building in New York City.
