Learn everything you've always wanted to know about the mail system at this museum, which has interactive galleries, research facilities, and perhaps most excitingly of all - an immersive underground rail ride.
This is the 100-year old system of tunnels, tracks and platforms located 21 metres underground that was used to move mail between sorting offices. You'll be in pitch darkness during the 15-minute ride, with loud noises and flashing lights to add to the atmosphere.
Back above ground, you'll see displays of the world's first stamps, vehicles used to deliver the mail, and historical costumes.
