St Mogue’s Well

Overview

Set on a gentle north-east-facing slope, St Mogue’s Well sits quietly within the old chapel and graveyard at Clonmore, County Carlow. Two small water streams converge here before flowing northwest into the surrounding fields, feeding a stone-lined basin that has drawn visitors for centuries. The well first appears on the Ordnance Survey six-inch maps of 1840 and 1924, and its current stone enclosure was erected in 1847 during a period when many Irish holy wells were formally protected to preserve their water and pilgrimage status.

Tucked into the rolling farmland of north Carlow, the site retains a distinct sense of stillness. A gravel path winds through a landscaped prayer garden, crossing a small footbridge over the stream before reaching the well-house. It is a place where early-Christian history, medieval stonework, and living folklore overlap in a compact, easily accessible outdoor space.

History & The Monastic Site

The well is named for St Maodhóg (anglicised as Mogue), a member of the Ua Dúnlaing tribe who founded a monastic community at Clonmore around 560 AD. At its peak, the settlement may have housed up to 5,000 monks and scholars, making it one of the most significant religious centres in early Leinster. The saint’s feast day is recorded as 11 April.

The monastery did not escape the turbulent centuries that followed. Historical records note repeated attacks:

• 774 – the site was burned
• 834-835 – Viking raiders struck the settlement
• 1040 – another assault led by Diarmait mac Mael-na-mBó
• The Annals of the Four Masters list the deaths of abbots in 771, 877, 886, 919, 920 and 972

Despite the violence, Clonmore remained a destination for pilgrims and scholars. An early-medieval poem by Brocán Cráibhtheach catalogues a collection of relics once kept here, including the little finger of St Maodhóg, which legend says was entrusted to the saint with the condition that it remain at Clonmore.

The graveyard still holds tangible evidence of this past. A seven-foot ringed granite high cross, known locally as St Mogue’s Cross, stands near the road. About twenty-four early-medieval cross-slabs are laid out in a paved area, many carved with intricate Celtic knotwork and interlacing patterns. In the north-western corner rests an Ogham stone, its faint vertical and horizontal strokes recorded by 19th-century antiquarians.

Folklore & Healing Traditions

Holy wells in Ireland often carry layered stories, and St Mogue’s Well is no exception. In 1930, a local man named James Byrne shared a tale with the National Folklore Collection that explains the well’s origins through the lens of oral tradition:

During the Viking raids, a large stone was said to have been blasted from the monastery grounds. It made three leaps across the landscape. The first landing created a spring that healed thousands of ailments. The second landing struck a robber’s castle, releasing swarms of flies that drove the occupants away. The third and final landing brought the stone to its current resting place. According to the story, the stone vowed to remain there until the end of time, promising that the surrounding land would become the most fertile in the parish and that no grass would ever grow over it.

Historically, the water was used for practical folk cures. School collection records from 1939 note that locals applied the water to sore eyes, warts, skin growths, and even cancer. The customary practice involved collecting water on three successive Fridays, sometimes pouring it over a nearby bullaun stone before application. While these rituals are no longer widely practised, they reflect the deep cultural role holy wells played in rural Irish life.

The Pilgrim Connection

For decades, a pattern (pilgrimage ceremony) was held here around 31 January, aligning with the feast of St Mogue (Aidan of Ferns). The pattern faded about thirty years ago, but the well remains a quiet place of devotion and reflection. Visitors and local walkers often pause at the well during walks through the Carlow countryside, bridging medieval pilgrimage customs with contemporary exploration.

What to See & Do

• The Well Basin – A stone-lined pool with clear, flowing water. Visitors traditionally dip a finger or collect a small amount for reflection.
• Prayer Garden – A community-maintained space featuring a gravel path, gentle waterfalls, wooden seating, and a bridge over the stream.
• Bullaun Stone – Located inside the well-house, this shallow carved basin was historically used in healing rituals.
• St Mogue’s High Cross – A seven-foot ringed granite cross standing close to the road, marking the monastic boundary.
• Cross-Slabs & Ogham Stone – Arranged within the graveyard, these weathered stones display early-medieval carving and pre-Christian script.
• Nearby Heritage Sites – A short walk leads to the ruins of Clonmore Castle, offering views across the local countryside. Across the road, the Triple Bullaun Stone sits as a separate archaeological feature.

Practical Information

Getting There & Visitor Etiquette

The well is most easily reached by car via the R727. From Tullow, travel east on the R727 for approximately 14 km, then follow the local road to Clonmore village. Alternatively, from Hacketstown, travel south for about 6 km. A short walk from the roadside parking layby leads past the stone wall of the graveyard to the well.

Treat the site with care: avoid climbing on the stone enclosure, do not remove stones or leave plastic waste, and keep dogs on a lead near the graveyard. If you wish to leave a token of gratitude, tying a small cloth (a “clootie”) to a nearby tree follows a long-standing Irish custom. Visit early in the morning or on a quiet weekday to experience the garden and stream.
