Philadelphia is the second largest city on the East Coast of the United States, and the fifth-most-populous city in the U.S.
In 1682, William Penn founded the city to serve as capital of Pennsylvania Colony. By the 1750s, Philadelphia had surpassed Boston to become the largest city and busiest port in British America, and second in the British Empire, behind London. During the Revolutionary War, Philadelphia played an instrumental role as a meeting place for the Founding Fathers of the United States, who signed the Declaration of Independence in 1776 and the Constitution in 1787.
Philadelphia is known for its arts and culture. The cheesesteak and soft pretzel are emblematic of Philadelphia cuisine. The city has more outdoor sculptures and murals than any other American city.
