The inspiration for Fangorn.
Puzzlewood is an ancient woodland site, near Coleford in the Forest of Dean, Gloucestershire, England. The site, covering 14 acres, shows evidence of open cast iron ore mining dating from the Roman period, and possibly earlier.
J. R. R. Tolkien, a frequent visitor to the Forest of Dean, may have visited Puzzlewood, and many believe Puzzlewood was the inspiration for the fabled forests of Middle-earth, such as the Old Forest, Mirkwood, Fangorn or Lothlórien contained within The Lord of the Rings. J.K Rowling is also said to have visited Puzzlewood, and it may have been this that influenced her idea of The Forbidden Forest in the Harry Potter books.
