A chapel built by Brangemore of Cornwall (Branguemore), who was slain by her son Espignogrés and buried beneath the chapel’s altar.
Gawaine and Perceval each visited it during their adventures. The mysterious “black hand” within the chapel had slain over 4,000 knights. Perceval discovered that the hand belonged to a devil. He did battle with the hand, and during the combat, lightning struck the chapel and burned it to the ground. Perceval drove away the devil by sanctifying the chapel.
