On the NW end of Cefn Sychbant is an annular oval bank of mixed grade rubble and boulders without an entrance. It measures 20.7m internally (E-W) by 18.3m and is 2.5m-4.3m wide and 0.7m high. A small recumbent boulder near the centre is perhaps the remains of a cist. The site is possibly an eroded large cairn though perhaps more likely a ring cairn.
