A prison officer's home is set to go under the hammer for £350,000 and it comes with a set of peculiar features.
It was once home to the chief warden at Huntingdon County Jail, Cambridgeshire, and comes with a World War Two Anderson bomb shelter, a prison well and its own cell.
The prison used to house thieves and murderers but its lifespan was short following a string of jailbreaks and it closed down in 1886.
Meanwhile the governor's house, the chapel and the chief warden's house survived which is now listed as a Grade II property.
Its current owners were told there is a dark steel cell somewhere in the house but they have not been able to find it.
They were passed on the secret after their dad bought the house in 1959 and it is now in need of refurbishment.
The charming property comprises of a kitchen, sitting room, dining room, utility and storerooms sprawled across the ground floor.
Upstairs features four bedrooms, a study and a family bathroom totalling an overall 2,200 sq ft.
The garden includes a brick garage and joining workshop with a WWII bomb shelter underneath and an old prison well.
Director Ian Kitson said the property is "fairly unique" due to its history and said "you can see why people would get excited by it."
He told how the current owners had been told there is a steel-lined cell somewhere in the house which they have never been able to find.
"I think the suggestion is that the wardens would put inmates there if they were particularly bad although why you would remove them from the prison I'm not sure," he added.
"It's extra quirks that adds to the mystery."
Huntingdon County Jail opened in 1828 and recorded 11,000 convicts in the 58 years it was used as a prison.
But a group of prisoners escaped just four months after it opened and a series of further jailbreaks followed.
Inmates were relocated to Bedford Prison when the site shut down in 1886 and demolished.
Residents in the area were not fond of the site which they felt "impoverished" the agricultural community.
