Sitting in a field close to the southern end of Llyn Llywenan, the largest natural lake on Anglesey, this pair of Neolithic (New Stone Age) tombs sit just 7ft/21.m apart.
Mewn cae wrth ymyl pen deheuol Llyn Llywenan, y llyn naturiol mwyaf ar Ynys Môn, dim ond 7 troedfedd/2.1m sy’n gwahanu’r pâr hwn o feddrodau Neolithig (Oes Newydd y Cerrig).
