I can find no good clue in Malory as to the whereabouts of this abbey, but from comparison with Mordrains and Nascien’s adventures at the Isle of Turnance and the Port of Perilous Rock, I would guess it likely to have been somewhere between Arthurian Cornwall and Avilion along the Devon–Somerset border.
The Vulgate, however, places the abbey in a wood near Norgales (North Wales).
