Search For Britain's Hidden Medieval Miracles, Mythical Features

From Droitwich salt springs to Loch Lomond, a geography professor is using a millennium-old manuscript  to hunt the UK's ancient and mythical features.

Andrew Evans has found 26 fantastical features documented in an ancient book called Wonders of Britain that was written by a monk between the 9th and 12th centuries. 

Many of these 'wonders' - which range from a lake with 60 islands on it to a shape-shifting burial mound - have been forgotten or only recorded in legends. 

Since then, Dr Evans has been travelling around the country using this manuscript to hunt down and locate these ancient features. Anglesey, the island situated off the north coast of Wales (inset), is home to four of the wonders described in the script.
