Saint Louis Science Center

The Saint Louis Science Center is a science museum at the south-east corner of Forest Park, which began as the McDonnell Planetarium in 1963. A skybridge over Interstate 64 links the planetarium to the main building, which has more than 700 hands-on exhibits on the earth and life sciences, physics and technology, a dinosaur hall and a five-storey OMNIMAX dome theatre.
