Ffynnon Cybi is a medieval holy well in Wales, protected by Cadw under reference MM332. The site lies upon Pridoli Rocks, undifferentiated formations of mudstone, siltstone and sandstone that date to the Pridoli epoch. These geological layers, being naturally permeable and fractured, would have provided reliable groundwater sources that made the location suitable for a sacred spring.
The well is dedicated to St. Cybi, a sixth-century Welsh saint, reflecting the medieval Christian practice of establishing shrines at natural water sources. Such sites became centres of pilgrimage and healing, combining pre-Christian reverence for springs with Christian sanctity. The construction and use of Ffynnon Cybi would have served both spiritual and practical purposes within its local community.
The monument represents an important category of Welsh religious heritage. Medieval holy wells often featured simple stone structures around the natural spring, though many have been substantially altered or lost. Ffynnon Cybi's survival and statutory protection acknowledge its significance as evidence of medieval devotional practice and the long continuity of sacred geography in the Welsh landscape.
