Carbonek, Corbenic
The castle in which the Grail was housed and where it was guarded by the Fisher King. It stood in the heart of the Grail Kingdom.
It is called Munsalvæsche in Wolfram’s Parzival, Illes in Diu Crône, and Corbenic in the Vulgate and Post-Vulgate Cycles.
In Perlesvaus, the Grail Castle was approachable only by a number of perilous bridges, guarded by two stone lions who mauled the unworthy. After the Fisher King’s death, it was conquered by the King of the Castle Mortal. All its holy artifacts disappeared until it was re-conquered by Perceval. A chapel outside the castle held the body of Joseph of Arimathea. It was also called Eden, the Castle of Joy, and the Castle of Souls. Anyone who died there went to heaven. After Perceval re-conquered it, Joseus the hermit served as its steward. Eventually, it crumbled to ruin, although the chapel remained in perfect condition.
Chrétien de Troyes does not give the Grail Castle a name. He describes it as a square tower of dark gray stone, flanked by two smaller towers, with hall, arcade, and drawbridge; all located in a valley between a river in a deep, rocky bed and a wood. The building is at first invisible to Percivale, even after the Fisher King in his boat has described it; its finally coming into Percivale’s view could have either a mystical explanation, or a nature one involving angles and perspective. When he meets his cousin (the Fisher King’s niece) next day, however, she remarks that there is no lodging within forty leagues along the way he has come. Hearing that he has lodged comfortably, she knows it could only have been at her uncle’s house. She does not identify it as an Otherwordly outpost, but her general reaction seems to suggest as much.
The description of this castle and its locale somewhat resembles those of both Gornemant’s Gohort and Ygerne’s (Igraine) Rock of Canguin in the same romance.
