Cave in cliffs on the northern slopes of Twr Pen-cyrn, with evidence of possible paleolithic use. Info from Coflein:
Eight bones apparently associated with 2 large fragments of antler excavated from the cave by J. Ellwood in 1818. All upper palaeolithic in form and possibly indicating a settlement site. There has been some damage by cavers. Notes from an Ordnance Survey record card, 1980.
