Those wanting to brave the night inside Britain's scariest prion finally have the chance to live out their wildest masochistic fantasies.
Shepton Mallet prison in Somerset, once home to child murderers, and criminals including Ronnie and Reggie Kray, has just reopened its doors to the public.
If you're desperate to see what life was like as one of Britain's most notorious incarcerated killers, then this is the perfect sleepover for you.

The infamous Kray twins - to name just a couple of the prison's most famous inmates - were moved to the jail from the Tower of London in 1952 for failing to enlist in national service.
The former prison, which shut down six years ago, is now open to thrill seekers who want to get a taste of prison life and sleep inside the walls of Britain's most haunted jail.
Visitors will have the chance to fully experience life as an inmate with the added 'haunted' bonus; they will sleep in a prison cell and hunt ghosts.
The tours - set up by Bump in the Night - first launched two years ago to provide visitors with an exhilarating yet scary experience and will return in October for a limited time over the Halloween period.

Those brave enough to take part will be given snacks and ghost hunting tools to meander around the inside of the prison's terrifying walls.
Visitors will be able to stay as late as 2am - or for those looking to extend their thrill time, a time-slot ending at 6:30am will also be available.
According to one employee, the tours are indeed terrifying. "I wasn't convinced it would be that scary before my first one but that has definitely changed now." she says.

"I've seen and heard all sorts including shadows when nobody is around, doors slamming shut and footsteps only to see nobody there."
Before it closed in 2013, Shepton Mallett was once Britain's oldest working prison and could hold just under 200 of the most high risk prisoners.
Since, it has become famous for its ghostly visitors and spooky nature. One visitor claimed to have heard doors slamming and the scuttling of footsteps when no one was around.

An employee similarly recorded: "When we were in the prison once my colleague leapt up from his seat and ran across the room."
"I asked what happened and he said he heard a loud growling sound in his ear, but we were the only two people in there."
If like us, you're not feeling all too thrilled at the idea of a slumber party in Britain's oldest and most haunted prison, the historic site will also be offering daylight tours.
