Erw Beddau (Acre of Graves) is supposedly the site of a battle between Prince Rhys ap Tewdr and Iestyn Gwrgant in about 1085-88; some sources say the battle is ficticious, others cannot agree on the date nor the opposing parties. 'Site of Battle' is marked on the first and second edition OS maps, which also show several mounds in the immediate vicinity. The area is now built over.
Source: various oral sources, gathered by Ordnance Survey field recorders and quoted on OS National Archaeological Record card: ST09NW9.
