This Victorian Gaol was built in 1829 by Joseph Aloysius Hansom, the man more famous for the eponymous Hansom Cab. The gaol was expanded in 1867 following an act which stipulated a minimum number of cells for solitary confinement. Around this time a heating system was provided for all the structure. But the building is more famous for less luxurious features, such as the treadwheel, which is still installed, designed to supply the gaol with water, though punishment through hard labour was its main aim. Other original features which still remain are the whipping room with whipping frame, the prison gibbet, the punishment cell and crank, another hard labour device. The gaol was closed in 1878, when it then became a police station until the 1950's. It is now a museum. Being a place of confinement, hard labour, torture and death, the gaol has many supernatural stories connected to it. In 1830 William Griffith was hanged for the attempted murder of one of his two wives.Richard Rowlands was hanged for the murder of his father in law. He went to his death pleading his innocence. Both were publicly executed. Flashing lights, hair being pulled, stones being thrown, doors banging, floating shadows in corridors, keys rattling and heavy footsteps are just some of the reported phenomena.
