Allegheny County, Pennsylvania

Allegheny County sits in the southwest corner of Pennsylvania. It’s home to Pittsburgh, the state’s second-largest city. The city sits at the meeting point of three rivers: the Allegheny, Monongahela, and Ohio.
This spot has been important for trade and industry for centuries. Steel used to be king here, but now healthcare and tech are big employers.
The county’s not all urban though. There are plenty of parks and green spaces to explore. Sports fans here love their teams. The NFL Steelers, MLB Pirates, and NHL Penguins all call Pittsburgh home.
