The north face of this substantial stone bears a wheeled cross carved in relief, a symbol that connects this place to Ireland’s early Christian heritage. Such crosses, with their characteristic circular ring connecting the arms, served as both religious markers and gathering points for pilgrims seeking the healing waters believed to flow from these blessed springs.

Holy wells like Porthaw have been focal points of devotion in Ireland for centuries, blending pre-Christian water veneration with later Christian traditions. The location at Ballynarry places this site within a broader landscape of ritual and religious significance that dots the Donegal coastline. These wells often attracted visitors during pattern days; annual pilgrimages where communities would gather to pray, perform ritual circuits called ’rounds’, and collect water for healing purposes.

The Archaeological Survey of County Donegal, compiled by Brian Lacey and his team in 1983, documented this site as part of their comprehensive cataloguing of the county’s archaeological heritage. While the boulder and its carved cross remain the most visible features today, the well itself continues to represent a tangible link to the spiritual practices that have shaped this corner of Ireland from the early medieval period through to modern times.
