This museum complex occupies the 1933 Union Terminal, an art-deco jewel still used by Amtrak. The interior has fantastic murals made of local Rookwood tiles. The complex includes a nifty Museum of Natural History (with a cave and real bats inside), a children's museum, a history museum, an Omnimax theater and a special hall for traveling exhibitions. Alas, the building is undergoing an extensive renovation through late 2018, so only the children's museum (adult/child $10.50/8.50) and special hall are open until then. Parking costs $6.
Comic book fans might recognize the building's exterior as the inspiration for the Hall of Justice, where Batman, Superman, Aquaman and other superheroes teamed up to fight crime. It's located two miles northwest of downtown.
