kitchen and store
"At the east of the chapel is a stone stair. Going down this the Prison-Store is found below in front, while at the back a passage leads to the Bakehouse and Kitchen... a neat place. There are three boilers with built in furnaces, a range with high pressure boiler behind for hot water, a new fire-clay sink, hot water tank, and cement floor."
(Ruthin Prison Inspection Report, published 1906.)
The prison-kitchen has had many different uses. Described on the 1831 plan of the gaol as the "Machine House" it probably contained a mechanism coupled to the treadmill used to raise water to a tank at the top of the building, as at other prisons.
