Description :
This part of the island of Anglesey, the strip of country 3.5 miles long by 1.5 miles wide bordering the south end of the straits, once possessed a remarkable concentration of megalithic burial chambers, no less than 17 being on record; among them the well known pair of cromlechs (actually a large single chamber with its ante-chamber opening to the south), which still stands close to the house of Plas Newydd, half a mile from Bryn yr Hen Bobl and in a very similar position. <1>

Plas Newydd consists of two chambers, a large and a smaller, and might be explained as yet another case of chamber and passage approach, but the stone dividing them functions as a supporter at the present time, thus shutting off one chamber from the other - a position which may possibly be due to the fact that the capstone of the larger chamber has moved outwards and its relations to its supports may therefore have been altered. <2>

Consists of a single large chamber and ante-chamber; the former measures about 10' by 3', is roofed by a cover stone 11.5' by 9.5' with a maximum thickness of 3.5' which now rests insecurely on five supporters; other uprights which completed the walling of the chamber are now prostrate or missing. The entrance to the chamber was at the SW end and here is a second chamber covered by a smaller stone - 6.5' by 5.5' which represents the end of a passage. A considerable part of the NE end of this cover stone has broken away and its supporters have partly subsided in an easterly direction. Various stones are partly exposed above the ground level in the immediate neighbourhood of the chamber, but no trace remains of the covering mound. Recently the level of the ground has been raised in extending a cricket ground. (RCAHMW, 1937)

Large polygonal chamber to the N with the E side open at present, and a smaller megalithic structure immediately adjoining and to the S of this big chamber, which has been variously interpreted as a passage; an antechamber, and a side chamber. <4>

Some damage to site from spray paint, dumped rubbish. <6>

Roughly rectangular chamber open to the SE with 6 uprights supporting a massive capstone, 4 x 3, 5 x 1.5m. A smaller chamber adjoins to the SW. It has a smaller capstone 2 x 1, 8 x 0.6m, supported by 3 uprights. A part of the capstone has broken off and lies between the two chambers. Siting: difficult to assess because of the buildings and landscaping. Bryn yr Hen Bobl is close by but not currently visible because of tree cover. (Smith, 2003)
