Pittsburgh is the second largest city in the Commonwealth of Pennsylvania. As of the 2000 census, the city itself had a population of 334,569, with 2,358,695 in the metropolitan area.

Pittsburgh is built at the confluence of three rivers (the Allegheny River, Monongahela River and the Ohio River), with the downtown area in the triangular portion of land formed by the rivers. The city is well known for its spectacular skyline of skyscrapers and bridges, the latter giving rise to two of its nicknames "The City of Bridges" and "The Bridge Capital".

As well as "The City of Bridges" and "The Bridge Capital", Pittsburgh also has a variety of other nicknames, including "City of Champions", "The 'Burgh" and "The College City". There are also nicknames linked to the city's industrial past such as "Iron City", "Steel City" and "Steel Town", and from the new industries that have arisen in the city such as "Roboburgh", which relates to Pittsburgh's growing robotics industry.
