Perthi Duon

The dolmen at PERTHI DUON, in the parish of Llanidan, three-quarters of a mile S.W. by S. of the (New) Church, is first mentioned by Rowlands. He says: "There is a shapely cromlech on the lands of Blochty... now thrown down and lying flat on its supporters". This was in 1723. From a sketch which he gives we see that it was called "Maen Llwyd".

[..] In the Arch. Camb. of 1846 a correspondent writes of this monument: "About twenty years ago (1826) brass or copper chisels were found in digging under it, when it fell down... there are still three uprights under it".
