Description : Two stones of a cromlech (largest 9ft x 5.5ft x 3ft thick) are (1871) the only visible remains in this particular grid (plus another stone). Its capstone was broken up many years ago. <1>
The so called cromlech part of which is still visible (1937) seems to have been a natural feature. (RCAHMW, 1937)
The cromlech appears to be a group of natural erratics. <3>
4 very large boulders. The 2 largest are possible in situ erratics. Another very large - several tons - deliberately placed against the 2 others and another, somewhat smaller has been deliberately placed to form a capstone across the two larger, forming a 'chamber' open to the east. The capstone has since split in 2 and collapsed into the chamber. At least partly man-made but could have been carried out during post-medieval clearance. However, the effort involved seems unjustified so a prehistoric date seems reasonable. Unfortunately, despite being scheduled the whole field has been thoroughly ploughed and reseeded so little remains of the former settlement. (Smith, 2003)
“This stood on low ground quite in a swamp the cap stone like that at Maen Llhwyd has been thrown down and its supporters lie near it. Also many other stones from three to five feet long to the number of thirty lie scattered in all directions around it.” (Skinner, 1802) (Sketch on p. 47).
