Llech Ronw

[1] A stone resembling the mythical Llech Ronw was discovered by Frank Ward in 1934 on the bank of Afon Cynfal.

Around the turn of the 21st century, a stone similar to Llech Ronw (possibly the same one found in 1934) was discovered along Afon Bryn Saeth.

In the Fourth Branch of the Mabinogi (the story of Math ap Mathonwy), Lleu Llaw Gyffes is betrayed by his wife, Blodeuedd, when she elopes with Gronw Pebyr.

[5] The story of Lleu Llaw Gyffes, Blodeuedd and Gronw Pebyr was the inspiration of Alan Garner's 1967 novel The Owl Service.

For the filming a replica of Llech Ronw was carved by local stone mason Edward Rowlands from a brief by Granada Television's chief designer Peter Caldwell: "An upright piece of slab stone or slate (like a gatepost) with a 4" dia rough hole cut through it 1'.0" from the top and a roughly etched grooved pattern of circles 2'.0" from the top.
