City Museum, St. Louis

Explore the Unexpected with City Museum. A brainchild of an internationally acclaimed artist Bob Cassily built in a hundred-year-old warehouse in downtown St. Louis, the museum has collaborated with many talented artists to repurpose pieces of old cities to build miles and miles of tunnels, climbers, bridges, slides, castles, secret passages, playgrounds, ball pits, and more. There's even a circus and a train. The effect is a mixture of children's playground with a surrealistic pavilion that is sure to fascinate both younger and older visitors. Plus don't miss City Museum’s iconic MonstroCity, an outdoor rebar playground featuring two planes propped on ladders, a fire engine, a castle turret, a 25-foot cupola, narrow crawlers arching four floors over a patio, and ramps and ladders connecting the whole thing together, mostly.
