The site's rediscovery was made by Lynda Mallett, Stuart Reddish and John Wood. The site had vanished from modern maps and was essentially lost to history until the local history enthusiasts made their discoveries.
Experts think the rediscovered site, which lies amidst the old oaks of an area known as the Birklands in Sherwood Forest, may also yield clues as to the boundary of the ancient Anglo Saxon Kingdoms of Mercia and Northumbria.
English Heritage, recently inspected the site and believes it is a national rarity. Thynghowe was a place where people came to resolve disputes and settle issues. It is a Norse word, although the site may older still, perhaps even Bronze Age. The word "howe" often indicates a prehistoric burial mound.
