Ardnaree – Ballina’s abbey and dolmen

📍 Ardnaree, Mayo

🏛️ Attraction

Last updated: 21 June 2026

Overview

Ardnaree sits on the east bank of the River Moy, just a short walk from Ballina’s town centre. Once a separate settlement, it has been part of Ballina since the 19th century, though it retains a distinct character shaped by centuries of monastic life, clan politics, and riverside trade. Known locally as Shanaghy (Seanachaidh), the townland packs a remarkable amount of history into a compact area. Visitors come to walk the grounds of a 15th-century Augustinian abbey, examine a Bronze Age dolmen tied to a grim local legend, and follow the river path used by anglers chasing Atlantic salmon.

History & Heritage

The Augustinian Abbey

The most visible landmark in Ardnaree is the ruin of the Augustinian Abbey of St Mary of Ardnaree. First referenced in papal records around 1410, the surviving stonework dates to c. 1427, when it was commissioned by Tadhg Riabhach Ó Dúda, a local chieftain of the O’Dowd dynasty. The abbey served as a centre of learning and religious life until the Dissolution of the Monasteries in the 16th century, though the O’Dowd family continued to support the community for generations. Today, the long nave, chancel, and south transept stand within the grounds of St Muredach’s Cathedral. The site is framed by a distinctive limestone gateway completed in 1880, which is listed on the National Inventory of Architectural Heritage.

The Dolmen of the Four Maols

A short distance east, behind Ballina railway station on Primrose Hill, stands the Dolmen of the Four Maols. This Bronze Age cist dates to roughly 2000 BCE and is locally known as the “Table of the Giants”. According to tradition, it marks the burial place of four brothers who murdered Bishop Ceallach of Kilmoremoy in the 7th century. The brothers were executed at Ardnaree, and their bodies were interred beneath the megalith. The structure stands approximately five feet high, supported by upright stones, and offers a quiet, atmospheric stop for anyone tracing the pre-Christian past of north Mayo.

Ardnaree Castle & the Battle of 1586

Long before the abbey was built, Ardnaree was the site of a strategic fortification. Recent fieldwork by the Ard na Riagh Preservation Group, combined with archival mapping, has pinpointed the location of Ardnaree Castle on Palmyra Hill in the Carrowcushlaun West townland. The site was officially added to the National Monument Service’s Historic Environment Viewer in June 2024, confirming its status as a protected heritage location. The castle guarded the bend in the River Moy and was the focal point of the Battle of Ardnaree in 1586, a brutal engagement between English forces and a combined Irish-Scottish army. While no above-ground walls remain, the confirmed footprint resets the origins of Ballina’s settlement by over a century.

What to See & Do

Walk the Abbey Grounds & Cathedral

The abbey ruins are open to the public year-round and sit within the grounds of St Muredach’s Cathedral. The limestone arches, carved doorway, and historic plaques provide a tangible link to medieval Mayo. The cathedral itself, built in the 19th century, is open during services, with the adjacent graveyard accessible at all times.

Explore the Dolmen & Riverside Path

From the abbey, a short walk east leads to the Dolmen of the Four Maols. The area around Primrose Hill and the railway line is quiet and well-suited for a reflective stroll. Continuing west, the River Moy walkway offers a level, paved route perfect for dog walkers and families. The path follows the east bank past weirs and fishing pools, with views across to the Ox Mountains.

Angling on the River Moy

The River Moy is internationally recognised for its Atlantic salmon runs. The Ridge Pool, located near the town centre, is a favourite among anglers, and the annual Ballina Salmon Festival in July celebrates the river’s heritage with street stalls, vintage vehicle displays, and angling demonstrations. Fishing requires a valid licence, which can be purchased online or at local tackle shops.

Catch a Local Match

Ardnaree Sarsfields GFC plays at their grounds on Castle Road. During the Gaelic football season (typically September to February), match days bring a lively community atmosphere to the suburb. Check the club’s social media pages for fixture dates.
