Philadelphia is the largest city in Pennsylvania.It is located in the southeast part of the state at the junction of the Schuylkill and Delaware Rivers.
Philadelphia, the City of Brotherly Love, was settled in 1681 by Capt. William Markham. Before the American Revolution, the city outstripped all others in the colonies in the field of education, arts, science, industry, and commerce. Philadelphia became the nation's capital in 1790, under the Constitution. It remained so until the seat of the federal government moved to Washington in 1800.
Philadelphia had emerged as a leader in America's Industrial Revolution within a half-century of the founding of the nation at Independence Hall. Today the steam locomotives and hat factories of the 19th century have been replaced by diverse manufacturing specialties such as chemicals, pharmaceuticals, medical devices, transportation equipment, printing and publishing. In the services sector, Philadelphia leads in subsectors such as health services, insurance carriers, legal services, and architecture and engineering services. Philadelphia is also home to branches of the U.S. Mint, the Federal Reserve System, and the Internal Revenue Service.
The city's harbor is one of the largest freshwater ports in the world. It is the centerpiece of the AmeriPort facility in south Philadelphia and a major shipping center with rail links to the Midwest and Canada.
The city is historically significant.It includes Independence Hall, where the Declaration of Independence was signed, and the Liberty Bell. Other significant tourist attractions are the Philadelphia Museum of Art, the Franklin Institute Science Museum, and the Philadelphia Zoological Gardens.
