Welcome to the Pittsburgh Portal
Pittsburgh is the second largest city in Pennsylvania and its metropolitan area ranks as the largest in both Appalachia and the Ohio River Valley while being the 22nd largest urban area in the United States.
Pittsburgh is dominated by the confluence of the Allegheny and Monongahela rivers which form the Ohio River. This strategic juncture was a major site of the North American theater of the Seven Years' War, with Great Britain winning control in 1758 to establish Fort Pitt in honor of "The Great Commoner", William Pitt. Following the American Revolution, the area grew as an important transportation center and primary gateway to the American frontier. 19th century coal and iron production made Pittsburgh into the world leader of steel and by 1910 the city was the eighth largest in the United States. With the collapse of American industries in the 1980s, Pittsburgh lost population but has successfully transitioned its economy into a world leader of healthcare, technology, education, and financial services.
Pittsburgh is known colloquially as "The Steel City", for its continued leadership in steel production, as well as "The City of Bridges" for its world record 466 structures. The city's official colors of black and gold are so symbolic that all pro-sports teams from the area, the Penguins, Pirates, and Steelers have also adopted them. Multiple publications have named Pittsburgh the "most livable city" in the United States for its low crime, affordability, and plentiful educational, cultural, and recreational amenities with its skyline vistas ranked by USA Today as second only to the Grand Canyon.

in 1982. It is still the largest domestically owned integrated steel producer in the United States, although it produces only slightly more steel than it did in 1902.
