Famous as an industrial center during the 19th century, to many Americans Pittsburgh still conjures stark images of billowing clouds emanating from steel and coal factories. Today's city, however, has a well-earned reputation for being one of the more livable metropolitan areas in the country. The city sits at the point where the Monongahela (oft referred to as 'the Mon') and Allegheny Rivers join the Ohio River, spreads out over the waterways and has hilly neighborhoods connected by picturesque bridges (all with footpaths), more than any other city in the US. Teeming with students from the many universities in town, it's a surprisingly hip and cultured city with top-notch museums, abundant greenery and several bustling neighborhoods with lively restaurant and bar scenes.
Scottish-born immigrant Andrew Carnegie made his fortune here by modernizing steel production, and his legacy is still synonymous with the city and its many cultural and educational institutions. Production dipped during the Great Depression but rose again because of mass-produced automobiles in the 1930s. When the economy and local steel industry took another major hit in the 1970s, the city's pride was buoyed by its local NFL football team: the Steelers achieved a remarkable run of four Super Bowl championships, a feat whose importance to the continuing psyche of some Pittsburghers can't be underestimated. After the steel industry's demise, Pittsburgh's economy refocused on health care, technology and education, and the city is home to several notable Fortune 500 companies, including Alcoa and Heinz.
