In the Silver Age and Bronze Age comics, a major Metropolis landmark is the Superman Museum. The Superman Museum features various exhibits dedicated to Metropolis' favorite superhero, similar to the Flash Museum in Central City. The Museum's exhibits were responsible for the origin of the Composite Superman. Members of the criminal organization the 100 at one point secretly used the Superman Museum as their base of operations, which was discovered by the superhero Black Lightning and his nemesis the Whale. Superman, under the effects of hypnosis, once went on a rampage and wrecked several pieces at the museum. The Superman Museum, like the Flash Museum, is also usually shown as existing well into the Legion of Super-Heroes' era, as shown in various stories and the 2000s television series "Legion of Super Heroes".
