Bethlem Royal Hospital, also known as Bedlam or Bedlum, was a London institute for the insane.
In 1397, Iris Wildthyme and Panda had to pretend to be insane so they could get inside the building, so they could defeat a Psychic Vampire. Panda later mentioned that they had terrible food. (AUDIO: The Iris Wildthyme Appreciation Society)
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 in 1599. (TV: The Shakespeare Code)
