Flag of Philadelphia, Pennsylvania.svg

Philadelphia, known colloquially as Philly, is the largest city in the U.S. state and Commonwealth of Pennsylvania, and the sixth-most populous U.S. city, with a 2018 census-estimated population of 1,584,138. Since 1854, the city has been coterminous with Philadelphia County, the most populous county in Pennsylvania and the urban core of the eighth-largest U.S. metropolitan statistical area, with over 6 million residents . Philadelphia is also the economic and cultural anchor of the greater Delaware Valley, located along the lower Delaware and Schuylkill Rivers, within the Northeast megalopolis. The Delaware Valley's population of 7.2 million ranks it as the eighth-largest combined statistical area in the United States.

William Penn, an English Quaker, founded the city in 1682 to serve as capital of the Pennsylvania Colony. Philadelphia played an instrumental role in the American Revolution as a meeting place for the Founding Fathers of the United States, who signed the Declaration of Independence in 1776 at the Second Continental Congress, and the Constitution at the Philadelphia Convention of 1787. Several other key events occurred in Philadelphia during the Revolutionary War including the First Continental Congress, the preservation of the Liberty Bell, the Battle of Germantown, and the Siege of Fort Mifflin. Philadelphia remained the nation's largest city until being overtaken by New York City in 1790; the city was also one of the nation's capitals during the revolution, serving as temporary U.S. capital while Washington, D.C. was under construction. In the 19th century, Philadelphia became a major industrial center and a railroad hub. The city grew from an influx of European immigrants, most of whom came from Ireland, Italy and Germany—the three largest reported ancestry groups in the city . In the early 20th century, Philadelphia became a prime destination for African Americans during the Great Migration after the Civil War, as well as Puerto Ricans. The city's population doubled from one million to two million people between 1890 and 1950.

Philadelphia skyline with the five tallest buildings being (left-to-right) Comcast Technology Center, Comcast Center, BNY Mellon Center, One Liberty Place and Two Liberty Place

At the top of the list of tallest buildings in Philadelphia is the 60-story Comcast Technology Center, which topped out at 1,121 feet (342 m) in Center City on November 27, 2017 and was completed in 2018. Comcast Technology Center is the tallest building outside lower Manhattan and Chicago, and is the tenth-tallest building in the United States, as of 2019. Philadelphia is home to more than 300 completed high-rise buildings up to 330 feet (100 m), and 56 completed skyscrapers of 330 feet (100 m) or taller, of which 31 are 400 feet (122 m) or taller.

The second-tallest building in Philadelphia is the 58-story Comcast Center at 974 feet (297 m), while the third-tallest building is One Liberty Place, which rises 61 floors and 945 feet (288 m). 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. Philadelphia is one of only five American cities with two or more completed buildings over 900 feet (270 m) tall, the others being New York City, Chicago, Houston, and Los Angeles.

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. Through most of the 20th century, a "gentlemen's agreement" prevented buildings from rising higher than the 548-ft (167-m) Philadelphia City Hall. The completion of One Liberty Place in 1987 broke the agreement, and Philadelphia has since seen the construction of ten skyscrapers that eclipse City Hall in height.

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 1.6 feet (0.49 m) shorter than Mole Antonelliana in Turin. Like other large American cities, Philadelphia went through a massive building boom in the 1970s and 1980s, resulting in the completion of 20 skyscrapers of 330 feet (100 m) or taller.
