In the Middle Ages, the Prison Gate was one of the gates to the earl’s castle on Binnenhof. From approximately 1420 the building was a prison used by the earls, later it was a prison for the Court of Holland. Since 1828 the building has had other purposes, since 1882 it has been a museum for instruments of torture and punishment. The thoroughfare past the Prison Gate dates from 1923; before that time houses were situated between the gate and the Hofvijver Pond. Through the gate you can see the statue of Johan de Witt. It reminds us of the spot where this Grand Pensionary and his brother Cornelis were murdered in 1672.
