The account of his life in ‘Buchedd Collen’ is late and quite untrustworthy. But he merits notice as the traditional founder of the ancient church of Llangollen, the mother church of the whole of the commote of Nanheudwy. He is not commemorated outside this area, save in the neighbouring parish of Ruabon, where there was once a Capel Collen. It is unlikely that the Deeside saint is commemorated in Trallwng Gollen, a township of Welshpool, or in Castell Collen, the Roman fort near Llandrindod. His festival was held on 21 May; hence the fair of Llangollen on that day (31 May after the change of style).
