St Osyth medieval prison marketed at 'paranormal industry'
"The Cage" in St Osyth, Essex, saw a woman imprisoned as a witch in 1582.
The current owner said she experienced "hostile and active" haunting in the property, which is priced at £290,000 and has been for sale for six months.
Estate agents Lawrence Antony Homes said the house was "set up to accommodate a paranormal business".
"We believe the ideal purchaser for this property would be someone connected to the paranormal industry," the agency said.
