The beating heart of Pittsburgh lies at the confluence of the city’s three rivers, where the Allegheny and Monongahela rivers combine to become the mighty Ohio. There, on a point of land that juts into the water, lies an exquisite state park, where musicians of all ilks gather to put on outdoor concerts in the summers with the Steel City’s famous fountain and skyline as backdrops. From that park, if you walk due east, past the towering glass spires of PPG Place and the bustling Market Square, you’ll encounter the Cultural District, the city’s arts haven, where operas, symphonies, ballets, and plays are constantly lighting up stages and marquees. Then, if you continue walking northeast for about a mile along Liberty Avenue, one of the city’s main drags, you’d arrive at a factory.
