Everyone recognises Tower Bridge. But did you know about its atmospheric bascule chambers, the Victorian workers who threw and caught white hot rivets while building the structure, or the derring-do/reckless pilots who flew right through the middle of it?

See Londonist: Time Machine for bonus facts and some of the stuff that didn't make the video.
