Driscoll] Another famous Philadelphia skyscraper is One Liberty Place, which is the city's 2nd-tallest building and the 17th-tallest building in the country.cite web|url=http://www.emporis.com/en/wm/bu/?id=1libertyplace-philadelphia-pa-usa|title=One Liberty Place|accessdate=2007-08-21|publisher=Emporis.com] Six of the ten tallest buildings in Pennsylvania are in Philadelphia.

Philadelphia's history of tall buildings is generally thought to begin with the 1744 completion of Christ Church, which served as one of America's first high-rise structures.cite web|url=http://www.emporis.info/en/wm/bu/?id=christchurch-philadelphia-pa-usa|title=Christ Church|accessdate=2007-08-17|publisher=Emporis.com] In the early 20th century, a 'gentlemen's agreement' existed that prevented buildings from rising higher than the 548-foot (167 m) Philadelphia City Hall.cite web|url=http://phillyskyline.com/bldgs/cityhall/index.htm|title=City Hall|accessdate=2007-08-21|publisher=PhillySkyline.com] Despite this agreement, Philadelphia amassed a large collection of high-rise buildings. The completion of One Liberty Place in 1987 broke the gentleman's agreement, and since then Philadelphia has seen the construction of seven skyscrapers that eclipse the City Hall in height.

Philadelphia has twice held the tallest habitable building in the United States, first with Christ Church and then with City Hall. Philadelphia City Hall reigned as the world's tallest building from 1901 to 1908, [cite web|url=http://www.galenfrysinger.com/philadelphia_city_hall.htm|title=City Hall|accessdate=2007-08-21|publisher=GalenFrysinger.com] and remains the world's tallest masonry building.cite web|url=http://www.emporis.com/en/wm/bu/?id=cityhall-philadelphia-pa-usa|title=Philadelphia City Hall|accessdate=2007-08-21|publisher=Emporis.com] Like other large American cities, Philadelphia went through a massive building boom in the 1970s and 1980s, resulting in the completion of over 20 high-rise buildings. The city is the site of 10 skyscrapers at least 500 feet (152 m) tall. Overall, Philadelphia's skyline is ranked (based on existing and under-construction buildings over 500 feet (152 m) tall) third in the Northeast (after New York City and Boston) and 12th in the United States, after New York, Chicago, Miami, Houston, Los Angeles, San Francisco, Dallas, Atlanta, Boston, Las Vegas and Seattle.ref label|note01|A|^
