One begins to understand that rocks are not nouns, but verbs — physical evidence of processes… —Marcia Bjornerud, Timefulness
This cromlech near Clynnog Church in Carnarvonshire has nothing very remarkable about it, except that the upper face of the covering-stone, measuring eight feet by five feet eight inches, is covered with small artificial hollows, apparently placed without any attempt at order. These markings are of more or less simple character. The most simple, and perhaps the oldest, form are the small cup-shaped hollows placed either in symmetrical order or scattered promiscuously. It may also be considered remarkable that the hollows are on the upper, not the under, side of the covering-slab.

Half a mile to the south-west of the village of Clynnog Fawr, stands near the sea a cromlech, consisting of a capstone and four props. This cromlech is described, under date 1772, in the old Rhyl MSS., compiled by the Rev. J. Llwyd, of Caerwys, as having upon its capstone "near a hundred shallow cavities running in oblique but almost parallel lines along, its surface, three much larger than the rest in a triangular position; it is supported by four strong bearers, and in length four cubits, in breadth three, its inclination towards the setting sun."

Looking SE from the dolmen: left, Gyrn Goch and Gyrn Ddu, Right in the distance, the striking trio of hills known in English as the 'Rivals'. At 564 m, the central, Garn Ganol is the highest in the Llŷn peninsula; to the north-west, Garn Fôr (444 m), to the south-east, Tre'i Ceiri — with its extensive hillfort — at 485 m.
This cromlech (the Welsh word for dolmen aka burial tomb) is well-known as the Bachwen Dolmen, an easy walk from Clynnog Fawr, on the western edge of Llŷn peninsula. The Neolithic dolmen is unique in Wales for its capstone with the numerous (promiscuous!) carved cupules. Pictures, comments and documentation can be found via the internet.
