It all seems to lead back to Radley, doesn't it?


Radley hotel

Radley Sanitarium is a mental institution where Mona Vanderwaal was sent, after her reveal as "A". Spencer Hastings was also housed there for a brief time, being placed in the same room as Mona was, and Marion Cavanaugh was also there for some time before the start of the series. It was a key place and location in Season 3. It has been closed down as of "Game On, Charles." It makes its last appearance as a Sanitarium in "Game Over, Charles". After the five year time jump, the hospital has been converted into a Hotel known as The Radley, which The Liars make frequent visits too.


The Radley Sanitarium is located in the fictional Darkette County, Pennsylvania. It plays into the series when Mona Vanderwaal is in this facility, but we can guess it has something to do with the story Alison told Hanna about the girl who was sent to a mental institution after killing her twin sister.

The first time in the series the name "Radley Sanitarium" is referenced in "The First Secret". The Liars are walking across a street when they think they see someone in the window of a haunted house. As they walk away, the door opens and the camera cuts to a taxi parked in front of the house with the words "Radley Sanitarium" on the side of it.

Mona is sent to Radley Sanitarium after revealing that she is "A" in "UnmAsked". She is visited by someone in a red coat, similar to that of Vivian Darkbloom's: as we'll learn in Season 3, that someone was CeCe Drake. However, it has been stated by Marlene King that this was a hallucination, and the event did not actually occur.

  • Hanna has been visiting Mona at Radley for answers. Mona remains quiet the first few times Hanna visits. She finally talks to Hanna. ("Blood Is The New Black")
  • Mona freaks out when Caleb comes to Radley to visit. He tells her that she better not do anything to hurt Hanna. She then starts screaming and throws a table across the room. This results in her doctor making the decision to allow no visitors. ("Kingdom of the Blind")
  • In "Crazy", Mona leaves her room while Hanna and Aria are visiting and runs to the Children's Ward, where she brushes some dolls' hair.
  • In the mid-season finale, "The Lady Killer", Mona breaks out of Radley by dressing as a nurse and flashing the guard a fake ID (taken from Hanna in an earlier episode).
  • In "She's Better Now", Mona is released.
  • In "Out of Sight, Out of Mind", Spencer Hastings was placed in Radley after she was found wandering around, covered in blood, and in a catatonic state. She was identified as "Jane Doe" when a hiker found her.
  • In "Will The Circle Be Unbroken?", an orderly, E. (Eddie) Lamb reveals to Spencer that Toby's mother, Marion Cavanaugh was a patient at Radley.
  • In "A DAngerous GAme", Spencer is released from Radley. Mona tells The Liars that she was shown how to get in and out of Radley during her stay.  

  • In "Game On, Charles", Radley is revealed to have shut down in light of the events surrounding Mona Vanderwaal and the Liars.
  • In "Don't Look Now", Charles DiLaurentis is revealed to have been in Radley since he was a child. The Liars try to find his file before it gets shredded with the others.
  • In "She's No Angel", The girls find out that Lesli Stone was a patient at Radley and was roommates with Bethany Young.
  • In the mid-season finale, "Game Over, Charles", the newly-revealed "A", Charlotte DiLaurentis (alias CeCe Drake), planned to bomb Radley with the assistance of Sara Harvey. Her plans fail, and she threatens to jump off the roof. After Alison pleads with her to stop, and with the police roaming the ground below, Charlotte jumps back onto the roof and says, "Game over", meaning her reign as "A" has ended.
  • In the following five years, Radley was transformed into a hotel. Ashley Marin is the manager.
