In
Arthurian legend, the
Val sans Retour (Vale or Valley of No Return) is an enchanted land in which the powerful sorceress
Morgan le Fay imprisons her lovers. The spell is eventually broken by
Lancelot. The Val sans Retour has been identified with an area of the same name in
Paimpont forest in
Brittany, southwest of
Rennes, which tradition has long held to be the site of the legendary forest of Broceliande. (from Wikipedia Encyclopedia)
