City Museum in St. Louis is a giant playground made from old buildings, bridges, and airplane parts all mixed together. It has tunnels, slides, and caves that you climb through instead of just looking at.
It is famous for being like a giant maze where kids and grown-ups crawl, slide, and explore for hours. People love that no other place in the world is quite like it.
A ten-story spiral slide and many shorter ones let you zoom from floor to floor in seconds.
Outside, twisty metal tunnels lead up to two real airplanes and a school bus hanging off the roof.
Artists built the whole place from recycled bridges, chimneys, and old machine parts.
