Here are 14 of the most bizarre, from those that turned out to be true to those that are still unsolved.
9. Lizzie the elephant
Though it might sound bizarre enough to be false, the rumour that Sheffield was once home to an elephant that helped out the steel industry is true - her name was Lizzie and she transported machinery around the city. Photo: ©Graham Hogg (cc-by-sa/2.0)

Executed in 1792 for robbery, Spence Broughton was a highwayman whose body was said to remain at Attercliffe Common for 36 years after the execution to serve as a warning to others. Photo: J. Edward Vickers/CC USA/Wikipedia
11. Meadowhall the prison
One rather bizarre rumour about Meadowhall follows that the shopping centre was designed in a similar way to a prison in case the building failed as a shopping centre and had to be converted. Photo: Gregory Deryckère/Wikipedia
12. Extra drinking time
It’s said that the original Red Lion at Gleadless straddled the old border between Derbyshire and Yorkshire, which both had different licensing laws. As a result, one side of the pub had to stop serving before the other. Photo: © JThomas (cc-by-sa/2.0)
