CityMu is a 600,000 sq. ft. playground housed in an old shoe factory in downtown STL. The whole thing is eclectic and bizarre with 30+ slides (one of which is 10 stories long), elaborate underground caves, a ferris wheel, indoor treehouse and tunnels, aquarium, circus, outdoor elevated playground, and even a schoolbus hanging off the edge of the rooftop. Definitely worth a visit, but wear climbing clothes/shoes!
The STL Science Center is one of the only free nonprofit science museums in the country, and it features more than 700 interactive experiences in ten galleries, as well as an indoor-outdoor GROW agricultural pavilion and gallery, the famous McDonnell Planetarium, and a four-story OMNIMAX® Theater.
Reception Venue (for the map - however, there's an amazing, eclectic antique market attached to the venue that's definitely worth a visit! it will be closed on the actual wedding day, but we highly recommend stopping by while you're in town!)
