Maybe half a mile away, in the same narrow band of land between the Afon Braint and the Afon Rhyd y Valley, there was another massive stone:
On a farm within this parish [Llangeinwen] there was, within these few years, a large stone pillar, which was probably one of those called Meini Gwyr, by Rowlands. It was about twelve feet high; but when the present farm-house was built, having no fear of antiquarian anger before their eyes, it was blasted, to make lintels for the doors and windows. The name of the farm, Maen Hir (the Long Pillar), however, preserves its memory.
From ‘The History of North Wales’ v2, by William Cathrall (1828).
Rowlands = his ‘Mona Antiqua Restaurata’.
