The Gevangenpoort was used as a prison from 1420 and shows the story of crime and punishment through the ages.
Prison Gate The Hague is comparable to the Tower in London and the Conciergerie in Paris, also ancient prisons.
One can imagine what happened here centuries ago because of the torture instruments on display.
On display are neck and handcuffs, branding irons, executioner swords, bone blocks, thumb screws, breaking wheels, knee splitters and body strechers.
