St Gwenfaen’s Well, Rhoscolyn

Even though we had excellent directions to find St Gwenfaen’s Well, which is at Rhoscolyn on Holy Island near Holyhead, actually arriving at the well  took us slightly by surprise. It was just beside the costal path, in a little hollow, totally unmarked when I was expecting it to be a little further on. The well is located on  clifftops overlooking the sea.

St Gwenfaen’s is one of the best preserved wells on Anglesey. There remains a two room structure, the floor level being around four feet below the surrounding landscape. Within the building there is  an antechamber with four stone seats and  a samll well chamber. The well into which the spring rises is about three feet square. The water flows out from the well into a  second  pool, outside the building which has steps down to the water to enable bathing. From this pool the water forms a stream which runs down towards the cliff edge.

The well is of a drystone construction, built using large grey-whitish coloured stone.

The church of St Gwenfaen, the only church in Wales dedicated to her, is in the village of Rhoscolyn, about half a mile from the well. Rhoscolyn was formerly called Llanwenfaen.

Very little is known of the life of Gwenfaen.  She was the daughter of Pawl Hen of Manaw, which has  been interpreted as indicating that he was from the Isle of Man but more likely to relate to Manaw on the Firth of Forth.  Gwenfaen’s brothers  were the Saints Peulan and Gwyngeneu who also had cells in the Holyhead area.

It is believed that she founded a cell at a site near to her well. There is no evidence of this, although the first known church dedicated to her in the area dates from 630. Her legend, drived from the local church website is that she was chased away from her cell by druids, and that she escaped by climbing the rock stack off Rhoscolyn Head. The tide came in and she was carried away by angels. This is how the Saints Bay got its name.

The well is traditionally resorted to for the cure of mental disorders, offerings of two white pebbles were thrown into the water by visitors to the well.

The existing church dates from around 1870, although it incorporates many features recovered from an earlier 15th century church which was destroyed by fire.

Gwenfaen’s feast day is normally given as 4th November, although some accounts have it as the 3rd or the 5th.

Coflein record


  1. Having read the instructions to find this well in your “excellent directions” link above, I found this Ordnance Survey map Grid Reference: SH2594975436 on this website – This is very specific and (together with the written instructions) makes it easy to place exactly where the well is when looking on an O.S. map (1:25000 is best). This places it just inland – EAST – of Porth Gwalch.

    1. Thanks Ian – yes the written instructions get you close and as you say having the map gets you there. I find these days having GPS on my phone helps so much in finding some of the wells that have little or no trace remaining. This one obviously is easier, though it does still spring up (so to speak) on you a little by surprise as it is so well hidden in the landscape
