Cadw SAM No.=CN057
A tear-drop shaped enclosure, c.100m N-S by 80m, occupying a promontory above the Afon Llyfni, accessible only from the NE, where it is defined by double banks & ditches run.
Trenching of the inner rampart, 1887 & 1939, showed it to be a ruined stone walled bank.
A mound within the enclosure may be artificial.
