Overview
Three weathered sandstone crosses stand in a field on a bend of the River Blackwater, and a fourth, by local tradition, lies in the river itself. This is Castlekeeran, known historically as Diseart Chiaráin (the Hermitage of Ciarán), the holiest corner of an 8th-century monastic settlement just northwest of Kells. It is a small, unstaffed site enclosed by a low stone wall and a hawthorn hedge, with the crosses, a fragment of the original church and a rare Ogham stone the main things to see. Don’t come expecting the carved biblical panels of Monasterboice – these crosses are deliberately plain. The reward here is the quiet and the setting, on a working farm with the river close by. It sits within Ireland’s Ancient East and the wider Boyne Valley.
History and legends
The monastery was founded by Saint Ciarán, a descendant of the Fiacha Araidhe of north-eastern Ulster. The annals record his death on 14 June, though sources differ on the year – Wikipedia gives 770, others 775; either way, 14 June is still kept as his feast day. The community thrived for centuries, producing several noted abbots including Siadhal (d. 855), Consudh (d. 868), and Dubhthach (d. 961).
Its prominence, however, made it a target. Viking raiders led by Godfrey, son of Sitric, plundered the site in 949. Decades later, in 1170, Diarmait Mac Murchada (Dermot MacMurrough) attacked the monastery during the turbulent period of the Norman incursions. Following the Dissolution of the Monasteries, the lands passed to the Knights Hospitaller, then to the Crutched Friars of St John the Baptist at Kells, before eventually coming under the control of the Plunket family in the early modern era.
Local folklore adds a colourful layer to the site’s past. Legend holds that St Columba once attempted to steal one of Castlekeeran’s high crosses for his own monastery at Kells. When Ciarán discovered the theft, he confronted Columba, who hastily pushed the stone into the River Blackwater to hide it. Locals say the cross remains submerged in the riverbed to this day.
What to see
The walled graveyard is small but densely packed with historical markers. Take time to examine the following features:
- The High Crosses: Three large sandstone termon (boundary) crosses stand within the enclosure. Unlike the intricately carved crosses found at nearby monastic sites, these are deliberately plain, reflecting early Irish stone-cutting traditions. They mark the sacred boundary of the original monastery.
- The Ogham Stone: Uncovered in 1898 during grave-digging, this stone bears the inscription COVAGNI MAQI MUCOI LUGUNI, with a more recent reading adding letters to give T[…]COVAGNI MAQI MUCOI LUGUNI ITI. It records a personal name and lineage. It is set against the north wall of the ruined church, but upside down – look closely and the lettering runs the wrong way.
- Church Ruins & Grave Slabs: A fragment of the original church wall remains, with an early Christian grave slab set into it. The stonework offers a quiet glimpse into early burial customs and ecclesiastical architecture.
- St Ciarán’s Holy Well: A short walk west of the graveyard leads to the holy well, which has long been associated with healing waters. It remains a place of quiet reflection and local tradition.
Visiting information
- Access & Parking: The site sits on private farmland. Follow the signposted lane off the N3 near Carnaross. A gate marked ‘Castlekeeran Crosses’ leads to a farm-gate parking area. Parking is free, but the ground is uneven and grass-covered, so sturdy footwear is essential.
- Opening Hours: The site is unstaffed and open year-round during daylight hours. There are no formal gates or entry fees.
- Accessibility: The terrain is a sloping field with uneven ground and a hawthorn hedge boundary. It is not suitable for wheelchairs or pushchairs, and visitors with limited mobility may find the approach challenging.
- Etiquette & Respect: The enclosure is still an active graveyard. Please keep to the marked grass path, avoid climbing or leaning on the crosses, and do not touch the Ogham inscription to preserve the ancient lettering. Early morning or late afternoon light works best for photography, casting long shadows across the stones.

Getting there
- By Car: From Kells, head north on the N3 toward Carnaross. Turn left onto the local road signposted for Castlekeeran. The drive takes roughly 10 minutes.
- Public Transport: The nearest bus stop is in Kells. From there you can arrange a short taxi ride or walk roughly 2 km (about 30 minutes) along the rural lanes to reach the site.
Nearby attractions
Castlekeeran pairs well with other heritage stops in the Boyne Valley. A short drive brings you to the Kells Historic Trail, the medieval ruins of the Abbey of Kells, and the passage tombs at Loughcrew. The Boyne River greenway adds walking and cycling routes nearby. Best plan: see Castlekeeran first thing for the long morning light across the crosses, then drive the ten minutes into Kells, where the monks’ books and treasures ended up after the Viking raids forced them east.
