A memorial was constructed not far from Foel Fadian next to the road at Rhiw Fawr in remembrance of the welsh journalist Lewis John Wynford Vaughan-Thomas. It was constructed after his death, completed and unveiled in 1990 in the form of a toposcope looking north-west out over the rolling hills and mountains of Wales. The memorial was constructed here, not because he had any connections with the area, but because he felt that the view from here towards Snowdon was the best in Wales.
