List of tallest buildings in Philadelphia explained

Philadelphia, the largest city in the U.S. state of Pennsylvania, is home to more than 300 completed high-rise buildings up to 330feet,[1] and 58 completed skyscrapers of 330feet or taller,[2] of which 34 are 400feet or taller and are listed below.

, the tallest building in the city is the 60-story Comcast Technology Center,[3] which topped out at 1150feet in Center City on November 27, 2017, and was opened in 2018.[4] [5] [6]

Comcast Technology Center is the tallest building in the United States outside New York City and Chicago, and is ranked as the 14th-tallest building in the United States, and as the 96th-tallest in the world.[4] The second-tallest building in Philadelphia is the 58-story Comcast Center at 974feet,[7] while the third-tallest building is One Liberty Place, which rises 61 floors and 945feet.[8] One Liberty Place stood as the tallest building in Pennsylvania for over 20 years until the completion of Comcast Center in 2008. Seven of the ten tallest buildings in Pennsylvania are in Philadelphia; the remainder are in Pittsburgh.[9] Philadelphia is one of only five American cities with two or more completed buildings over 900feet tall; the others are New York City, Chicago, Houston, and Los Angeles.[10]

Philadelphia's history of tall buildings is generally thought to have begun with the 1754 addition of the steeple to Christ Church, which was one of America's first high-rise structures.[11] Through most of the 20th century, a "gentlemen's agreement" and economic restraints[12] prevented buildings from rising higher than the 548-ft (167-m) Philadelphia City Hall.[13] Despite this, Philadelphia amassed a large collection of high-rise buildings. The completion of One Liberty Place in 1987 broke the agreement,[13] and Philadelphia has since seen the construction of eleven skyscrapers that eclipse City Hall in height.[2]

Philadelphia has twice held the tallest habitable building in North America, first with Christ Church, then with City Hall. The latter reigned as the world's tallest building from 1894 to 1908, and is currently the world's second-tallest masonry building, only 1.6feet shorter[14] than Mole Antonelliana in Turin.[15] [16] Like other large American cities, Philadelphia experienced a massive building boom in the 1970s and 1980s, resulting in the completion of 20 skyscrapers of 330feet or taller.[17]

Tallest buildings

This list ranks completed and topped out skyscrapers in Center City Philadelphia that stand at least 400feet tall, based on standard height measurement, including spires and architectural details but excluding antenna masts. An equal sign (=) following a rank indicates the same height between two or more buildings. The "Year" column indicates the year in which a building was completed. The only demolished building that would have ranked on this list was the 492adj=onNaNadj=on One Meridian Plaza, razed in 1999.[18]

Timeline of tallest buildings

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,[13] 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.
