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.
