(Pentre Poeth farm no longer exists. It was in the region close to Cwm-cynwal and Pant y cadno just off the road from Bwysfa fawr near Trecastle on the way to Belfont farm Crai. There now is a large water tank on the place where the farm stood, which now is on Tircapel (Ty'r capel) farm ground. Tirchapel farm is believed to be named after an ancient chapel, Capel Illud, and it may be that the Llywel stone originally stood at  the chapel site. The site is along the Roman road from Caerleon to Carmarthen, the Via Julia Montana). In 1878, the Llywel stone was acquired by the British Museum where it is on display. The inscription on the stone is 'MACCVTRENI + SALICIDVNI'. A National Park booklet provides a drawing of the Llywel Stone and states that copies reside with Llywel Church and the Y Gaer cultural hub in Brecon.
