In Crawfordsville, Indiana, there's a rotary jail: an invention that, with hindsight, should probably never have been built. But it was, here and in other towns across the United States. It might have sounded like a good idea on paper, but in practice, it had a few unfortunate problems... including occasional accidental amputations.
