Just hearing the name "The Coffin" induces fear into most people.
What you're looking at is one of the most frightening devices used during the middle ages. If you committed a serious enough crime (keep in mind back then you would be killed for having the wrong beliefs...). Mostly this torture would be implemented inside a dungeon, but sometimes the victim would be put on display in the town. Villagers were also free to do what they pleased to the suspected heretic. More places they would hang the cage from is off the sides of castles and bridges so the crows could have a nice bite to eat.
