Ryall State Prison is the name of the prison in which Murphy Pendleton spent his time incarcerated. At the start of Silent Hill: Downpour, he is being transferred to Wayside Maximum Security Prison, following undisclosed events at Ryall. Some of the guards and most of the prisoners are very hostile towards him; however, there is one prison guard, Frank Coleridge, who is on good terms with Murphy.
In memos, the name of the prison is shown as "Ryall State Prison", although in Murphy's mugshot, it is shown as "Ryall State Corrections Facility", and on the side of the bus "Ryall State Correctional Facility". It can be assumed that the correctional facility is a branch of Ryall State Prison, and not the name for the entire prison itself.
The exact location of the prison. however is not known. It can be speculated that the prison is not too far from Silent Hill.
