Pittsburgh

Pittsburgh is a city in the state of Pennsylvania in the United States and the county seat of Allegheny County. A population of 302,971 residents live within the city limits as of the 2020 US Census, making it the 68th-largest city in the U.S. and the second-most populous city in Pennsylvania, behind Philadelphia. The Pittsburgh metropolitan area is the anchor of Western Pennsylvania; its population of 2.37 million is the largest in both the Ohio Valley and Appalachia, the second-largest in Pennsylvania, and the 27th-largest in the U.S.

Pittsburgh is located in the southwest of the state, at the confluence of the Allegheny River and the Monongahela River, forming the Ohio River.[4] Pittsburgh is known both as “the Steel City” for its more than 300 steel-related businesses and as the “City of Bridges” for its 446 bridges.[5] The city features 30 skyscrapers, two inclined railways, a pre-revolutionary fortification and the Point State Park at the confluence of the rivers. The city developed as a vital link of the Atlantic coast and Midwest, as the mineral-rich Allegheny Mountains led to the region being contested by the French and British empires, Virginians, Whiskey Rebels, and Civil War raiders.
