Bethlem Royal Hospital

Bedlam Royal Hospital, also known simply as "Bedlam," was a madhouse where William Shakespeare was put after the grief he experienced after the death of his son drove him temporarily insane. With the Tenth Doctor and Martha Jones, he went there to speak with Peter Streete. (DW: The Shakespeare Code)

When asked by Ace whether Gabriel Chase was a madhouse with the patients in charge, the Doctor replied that given a chance, it could be Bedlam. (DW: Ghost Light)
