Gotham City Olympus

&nbsp The Gotham City Olympus was a nightclub owned by the criminal Maxie Zeus.

Before Arkham
Unlike most buildings in North Gotham, the Gotham City Olympus Nightclub was still in full operation, originally owned by Maxie Zeus.

Although Maxie disppeared in Arkham Asylum after one too many rounds of electroshock therapy, the club kept running in his absence, leaving some to think its owner hasn't gone far.

Batman: Arkham City
The Olympus was closed down once Arkham City was approved, and any use of it by inmates is unknown. But, it was one of the many buildings that the Riddler hid one of his trophies for the Dark Knight to locate.
