Cropmarks of a concentric antenna-style defended enclosure were discovered during RCAHMW aerial reconnaissance on 9th July 2018 (AP_2018_3166, 3170, 3175), during the 2018 drought, on a steep hillslope above Aberhoffnant farm, overlooking the River Teifi. The site comprises a large concentric ditched enclosure with a south facing inturned gateway. A third outer ditch, or palisade trench, leaves the gateway and swings south, then west upslope. Overall the complex measures approx. 160m across.
