City Museum: A 10-Story Former Shoe Factory Transformed into a Massive Urban Playground

The 600,000 square-foot urban playground, City Museum, in St. Louis is probably the largest park of its kind anywhere. A former 10-story international shoe factory was constructed by artist and sculptor Bob Cassilly

The jungly gym contains 10-story slides, multiple floor slides, a rooftop Ferris wheel, restaurants, ball pits, an aquarium and the use of repurposed airplanes, among many other unbelievable features, which are perpetually under construction. If you are planning a last summer trip, this is the best bet for your kids!
