Bethlem Royal Hospital

Bethlem Royal Hospital, also known as Bedlam, was a London institute for the insane, based in Bishopsgate. (REF: Doctor Who: The Encyclopedia). William Shakespeare was put there when the grief he experienced after the death of his son drove him temporarily mad. 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 Seventh Doctor replied that given a chance, it could be Bedlam. (DW: Ghost Light)
