Overview & History
Situated just north of Johnstown beside a crossing of the River Goul, Grangefertagh is one of County Kilkenny’s most atmospheric medieval sites. Originally known in early Irish as Fearta-Cáerach (“the sheep’s tomb”), the settlement was founded in the 6th century by St Ciarán of Saigir as a major ecclesiastical centre for the kingdom of Osraige. Its riverside location quickly made it a strategic prize, drawing it into centuries of conflict and cultural transformation.
The Annals of the Four Masters record a fierce Viking raid in 861 AD, when Cerball mac Dúnlainge defeated an invading force at the monastery. Later, in 1156, High King Muirchertach Mac Lochlainn famously set fire to the round tower while the chief master Eochaidh O’Cuim was inside – an event that cemented the site’s place in Irish historical memory. Following the Norman arrival, the de Blancheville family established a house of Canons Regular of St Augustine here in the early 13th century. The priory faced hardship in the late 14th century, but a 15th-century rebuilding by canon Thady Megirid revitalised the complex. The site continued in use long after the 1541 Reformation dissolution, with the church serving Protestant congregations until the roof collapsed in 1780.
Architecture & Key Features
Today, Grangefertagh is a protected National Monument managed by the Office of Public Works (OPW). While interior access is restricted to preserve the fragile stonework, the exterior offers a wealth of architectural detail and historical layers.
The Round Tower
Standing at 31.5 metres, the round tower dominates the skyline and remains visible for kilometres across the surrounding farmland. Originally serving as a bell-house (cloigtheach) and refuge, the tower features:
- A base diameter of roughly 4.7 metres, tapering to 2 metres at the top
- Nine windows in total: four triangular-headed openings on the bell-floor facing the cardinal points, plus five varied windows along the shaft
- A north-east-facing doorway positioned 3.3 metres above ground, originally reached by a wooden ladder
- A rare surviving fragment of the original conical capstone, making it one of Ireland’s few towers with intact roof elements
The Priory Church & Handball Alley
The 13th-century Augustinian church is built from local limestone and runs east-west. Though the western nave has collapsed, the remaining structure still reveals a two-light ogee-headed window in the north wall and a later 15th/16th-century north chapel, known locally as the Kilpatrick chapel. Interestingly, the surviving nave wall now doubles as a traditional Gaelic handball alley, keeping the site connected to local community life.
The Mac Giolla Phádraig Tomb
Inside the north chapel rests one of the finest medieval tombs in the region. Carved in the mid-16th century by master sculptor Rory Tunney (who also worked at Jerpoint Abbey), the double effigy depicts John Mac Gilla Patrick and his son Brian. The stonework features intricate lierne vaulting, foliate quatrefoils, and decorative tracery. A Latin inscription on the tomb honours the FitzPatrick dynasty and notes Katherine Molloy, Brian’s mother, as the tomb’s erector. Nearby, a 13th/14th-century grave slab bears a raised four-armed trefoil-headed cross.
