• Best from about 8, since the museum itself says it suits kids under 8 less well
• No buggies inside: the old building has narrow staircases, high thresholds and uneven floors, and isn't wheelchair accessible
• Timed entry slots with a cap per quarter hour, so book ahead for weekends and school holidays

The Prison Gate was the entrance to the castle of the Counts of Holland, then for centuries a prison. A museum since 1882, it holds old cells and the largest collection of punishment and torture instruments in the Netherlands.

In the courthouse exhibition, kids feel how heavy a leg block is, see how thumbscrews work, and end the visit playing judge.
