City Museum

St. Louis, Missouri

City Museum is housed in a sprawling, 10-story, 600,000-square-foot former shoe warehouse. A school bus dangles from the building’s roof. The ultimate jungle gym extends from the windows. And that’s just where the magic begins. Inside City Museum are dark caves, crashing waters, and secret passageways—plus all the ramps, domes, tunnels, chutes, and slides a kid could want. Most of City Museum’s attractions are made of recycled materials. “City Museum is an evolving sculpture,” says general manager Rick Erwin. “It’s like the world’s largest playground.” —Rebecca Katzman
