(Belle Reve Penitentiary is a fictional prison and sanitorium in the DC Universe) On the television series Smallville, Belle Reve Sanitarium is an insane asylum. The meteor freak villains Clark fights are almost always held here for their insanity, similar to how many of Batman's enemies end up in Arkham Asylum. In the episode, "Freak", Chloe Sullivan laments that all meteor rock-infected Smallville citizens end up either dead or in Belle Reve, indicating that insanity is a likely side effect of kryptonite exposure in humans. Belle Reeve held the likes of Lex and Lionel Luthor.
