Summary

Multivalate, contour hillfort in commanding position on summit of rocky spur of an isolated hill top overlooking the Afon Teifi to N at its confluence with the Afon Clettwr and confluence with the Afon Tyweli. Very steep surrounding slopes to N and E, slightly less elsewhere. Irregular shape, measuring c. 160m N-S by 125m, with internal area 1.5ha. Defended on N, E and W by a single slight bank to 2m high externally, with outer terrace, c. 2m wide, being probable position of ditch. Traces of possible second scarp to SE. No ditch visible on NE where slopes steepest. On gentler SW side fine series of ramparts and ditches around entrance, reaching c. 4.2m high. Entrance has two large ramparts, with flat terraces between. Ends of outer rampart on either side of the entrance passage slightly inturned. Outside the ramparts on the SW Gardner, in 1932, identified remnants of a chevaux-de-fris, noting that formed of more or less pointed stones, some 0.6m high, inserted upright in the ground. Little remained by 1968 when Ordnance Survey visited site. Additional outer scarp on W just visible, and number of scarps in the wood on E, possibly part of defences. Around N angle traces of possible scarp of another ditch beyond that belonging to main rampart. Site is identified with the stronghold of Vortgern, or Gwrtheyrn. Pasture interior with bracken. Entrance wooded. Wooded surrounding slopes. On 1st Ed. OS map (1889). Minimal investigations, undated.

Entrances

On gentler SW side fine series of ramparts and ditches around entrance with twin hornwork, reaching c. 4.2m high. Entrance has two large ramparts, with flat terraces between. Ends of outer rampart on either side of the entrance passage slightly inturned. Outside ramparts on SW side, Gardner, in 1932, identified remnants of a chevaux-de-frise, noting that formed of more or less pointed stones, some 0.6m high, inserted upright in the ground. Little remained by 1968 when Ordnance Survey visited site.
