English folklore is the folk traition which has developed in England over a number of centuries. Some stories can be traced back to their roots, even predating the Roman invasion of Britain, while the origin of others is uncertain or disputed. England abounds with folklore, in all forms, from such obvious manifestations as the traditional Arthurian legends (which were originally strictly Britonic) and Robin Hood tales, to contemporary urban legends and facets of cryptozoology such as the Beast of Bodmin Moor.
