"City Hall isn’t the tallest building in Philadelphia, but it’s still hard to miss it when you're walking around Center City. Look up and you’ll see William Penn, 548 feet above the ground, looking out over the city he designed. The views of the building—the largest municipal building in the United States—are impressive, but don’t simply stroll past. Dilworth Park, which hosts an annual Christmas market, a seasonal ice skating rink, and free summertime fitness classes, is on its doorstep. City Hall helps make the case that outside of Washington D.C., Philadelphia is the best city in the U.S. for travelers interested in American history and government." - Regan Stephens, Devra Ferst
