Portcullis gateway of Pentonville Prison

Book illustration of the Portcullis gateway of Pentonville Prison, designed by Sir Charles Barry, from page 112 of 'The criminal prisons of London and scenes of prison life' by Henry Mayhew and John Binny. "The building was commenced on the 10th of April, 1840, and completed in 1842, at a cost of about £85,000, after plans furnished by Lieut.-Col. Jebb, R.E. It was first occupied in December of the latter year, and was appropriated, by direction of Sir James Graham, the Home Secretary at that period, to the reception of a selected body of convicts, who were there to undergo a term of probationary discipline previous to their transportation to the colonies."
