Because of tradition and The City of Philadelphia's Percent for Art Program, public art plays a large role in the city landscape. (1 percent of budgets for buildings are allocated to publicly accessible art.) Large scale game pieces (from Monopoly, Sorry, chess, checkers, bingo, and dominoes) can be seen around the plaza, part of a piece called "Your Move" (1997). The wheelbarrow from Monopoly is closest, with other pieces in the distance. The large black looming sculpture is "Covenant of the People".
City Hall itself is undergoing a rejuvenation with major cleaning and restoration. Having first lived in Philadelphia since 1989, I never realized that City Hall was made of gleaming white marble, having only seen a drab gray exterior. City Hall is home to hundreds of sculptures by Alexander Milne Calder, including the William Penn statue.
