Mathematical Bridge by CandS
While we were punting down the River Cam we came across the Mathematical Bridge...our guide told us that many years ago the maths students couldn't work out how the bridge was built without any bolts etc so they pulled it apart, then they couldn't get it to go back together without the bolts so they had to use them to join the bridge back together...
