Canterbury gaol was established in 1806/8 of which only the entrance block still remains.Tthe original prison had a central three storey ‘hub’ containing the governor’s house, with the chapel occupying part of the first floor. Radiating from this were three detached wings. The north wing had three floors, with the other two having two storeys. Around the prison was a hexagonal perimeter wall including the surviving gatehouse. Throughout the 19th century and right up to the Second World War there were several phases of expansion and redevelopment but it was not until after the war that the northern part of the site developed.
