For nearly 60 years, the iconic James S. McDonnell Planetarium has been the place in St. Louis for all things space. Connected via the Skybridge over Interstate-64, the Planetarium Campus in Forest Park contains three floors of attractions dedicated to the wonders of space, aviation, and spaceflight. Relax under the largest artificial sky in the Western Hemisphere, see space history first-hand with our genuine space capsules, and have your every question about the universe answered by one of our Planetarium Educators.
