Pittsburgh, the largest city in Allegheny County and the second-largest in Pennsylvania, is situated at the confluence of the Allegheny, Monongahela, and Ohio Rivers. The city’s strategic location made it a vital transportation and manufacturing hub during the 19th and 20th centuries.

It was later renamed Fort Pitt and became a key location during the French and Indian War. During the 19th century, Pittsburgh rose to prominence as the heart of the steel industry, earning the nickname “Steel City.” The city’s economy shifted dramatically after the steel industry’s decline in the late 20th century, transitioning to a diversified economy centered around technology, healthcare, and education. Today, Pittsburgh is known for its revitalized downtown, its sports culture, and its strong university presence.
