The City Museum is a playhouse museum in St Louis, made with repurposed archtectural and industrial objects. It has caves, passages for kids to crawl around in, reconstructed refreshment stands, a litle railroad, and lots and lots of objects to gaze at. It is the brainchild of artist and entrepreneur Bob Cassilly and opened in 1997. It was full of people wndering around and lots of fun to visit.
We were there as part of our trip to Carbondale, Illinois to view the eclipse - all 2 minutes and 40 seconds of it.
