Philadelphia is the largest city in the Commonwealth of Pennsylvania in the United States. It is the sixth-most-populous city in the United States, the most populous city in the state of Pennsylvania, and the second-most populous city in the Northeastern United States, behind New York City. It is also the economic and cultural center of the greater Delaware Valley along the lower Delaware and Schuylkill rivers within the Northeast megalopolis.
In the 19th and 20th centuries, Philadelphia became a major industrial center and a railroad hub. The Philadelphia area's many universities and colleges make it a top study destination, as the city has evolved into an educational and economic hub. The city is known for its arts, culture, cuisine, and colonial history. It is also a biotechnology hub.
Philadelphia is the home of many U.S. firsts, including the nation's first library (1731), hospital (1751), medical school (1765), national capital (1774), university (by some accounts) (1779), stock exchange (1790), zoo (1874), and business school (1881). It contains 67 National Historic Landmarks and the World Heritage Site of Independence Hall. The city became a member of the Organization of World Heritage Cities in 2015, as the first World Heritage City in the United States.
