Brocéliande, earlier known as Brécheliant and Brécilien, is a legendary enchanted forest that had a reputation in the medieval European imagination as a place of magic and mystery. Brocéliande is featured in several medieval texts, mostly related to the Arthurian legend and the characters of Merlin, Morgan le Fay, the Lady of the Lake, and some of the Knights of the Round Table. It first appeared in literature in the Roman de Rou chronicle by Wace in 1160 and today is most commonly identified as Paimpont forest in Brittany, France.
Brocéliande is a place of legend due to its uncertain location, unusual weather, and its ties with Arthurian mythology, most notably the tomb of the legendary figure of Merlin. According to these accounts, the forest sheltered Morgan's magical Vale of No Return, the faery fountain of Barenton, and the place of Merlin's retirement, imprisonment, or death.
