St Cybi's Well

Hidden holy well with possible pagan origins

Nestled amid trees in a secluded spot at the base of Garn Bentyrch in Eifionydd (Gwynedd), this ancient holy site possesses an unmistakeable air of magic. Dedicated to Cybi, a 6th-century saint reputed to have lived in the area (the church in nearby Llangybi also bears his name), the well’s waters have long been believed to hold healing properties.

Today you can see two well chambers alongside a more recent caretaker’s cottage dating from the 18th or 19th century. Despite its association with St Cybi, it’s possible that the well’s sacred status may be pre-Christian in origin.
