Overview
Grangefertagh lies a short distance north of Johnstown in County Kilkenny, perched beside a crossing of the River Goul. The site is a state‑owned National Monument under the care of the Office of Public Works (OPW). Visitors can view the impressive round tower and the surviving fragments of a 13th‑century Augustinian priory church from the surrounding field. The monument is free to access and requires no advance booking – the only restriction is that interior access to the tower and church is prohibited for safety and preservation reasons.
Historical Context
Grangefertagh sits within the historic kingdom of Osraige (also known as Ossory), a Gaelic over‑kingdom that dominated much of what is now County Kilkenny from the early medieval period. The monastery’s foundation by St Ciarán of Saigir in the 6th century made it one of the early ecclesiastical centres of Osraige, alongside sites such as Saighir and Aghaboe. Its strategic riverside location meant the settlement was repeatedly drawn into the region’s turbulent history – from Viking raids in 861 AD to the 1156 burning by High King Muirchertach Mac Lochlainn. The later 13th‑century Augustinian priory reflects the Norman‑era re‑organisation of church lands in Osraige, while the 15th‑century reconstruction by Thady Megirid shows the continued importance of the FitzPatrick (Mac Giolla Phádraig) dynasty in Upper Ossory.
History
The monastic settlement at Grangefertagh was founded in the 6th century by Saint Ciarán of Saigir. In early Irish it was known as Fearta‑Cáerach – “the sheep’s tomb”. Its strategic position on the River Goul made it a target for Viking raids; the Annals of the Four Masters record a 861 AD attack in which Cerball mac Dúnlainge defeated a host of Vikings and took forty heads.
The round tower, a later addition, was erected as a symbol of the monastery’s wealth and as a bell‑house (Cloigtheach). In 1156 the high king Muirchertach Mac Lochlainn set fire to the tower while the chief master Eochaidh O’Cuim was inside – a tragic episode that entered Irish round‑tower lore.
The de Blancheville family revived the site in the early 13th century, establishing a house of Canons Regular of St Augustine. The priory flourished for several centuries, but by 1421 the community was described as “desolate, wandering and begging for their daily bread.” A partial reconstruction was undertaken in 1455 by Thady Megirid, a canon of Inchmacnerin. The monastic complex was dissolved in 1541 during the Reformation, yet the church continued in use for Protestant worship until the roof collapsed in 1780. Today the ruined nave forms part of a Gaelic handball alley, while the north‑side chapel houses a remarkable 16th‑century tomb of the Mac Giolla Phádraig (FitzPatrick) dynasty.
Architecture
Round Tower
- Height: 31.5 m (approximately eight storeys).
- Base diameter: about 4.7 m, tapering to roughly 2 m at the summit.
- Windows: nine in total – four triangular‑headed windows on the bell‑floor facing the cardinal points, and five lower windows (two triangular‑headed, two lintelled and one additional triangular‑headed) distributed along the shaft.
- Doorway: north‑east‑facing, 3.3 m above ground, originally accessed by a wooden ladder.
- Roof: a fragment of the original conical capstone remains, making Grangefertagh one of the few Irish towers with any surviving roof stone.
Church Ruins
- Built in the 13th century from limestone, oriented east‑west.
- Surviving features include a two‑light ogee‑headed window in the north wall and the later 15th/16th‑century north chapel (the Kilpatrick chapel).
- The western end of the nave has collapsed; the remaining nave wall now serves as a handball alley.
Mac Giolla Phádraig Tomb
The north‑side chapel contains a double effigy tomb of John Mac Gilla Patrick and his son Brian, carved in the mid‑16th century by the renowned sculptor Rory Tunney (who also worked at Jerpoint Abbey). The tomb displays high relief figures, decorated tracery, lierne vaulting and foliate quatrefoils. A Latin inscription reads: “Here lie the former good lords of Ossory John Mac Gilla Patrick and Lord Brian his son. Upon whose souls may God have mercy. Here lies Katherine Molloy, mother of Brian the erector of this tomb.”

The tower’s height and distinctive window pattern make it a landmark visible from many kilometres away. While interior access is prohibited, the surrounding landscape offers ample space for quiet contemplation, sketching or photography. The River Goul provides a pleasant backdrop, and the nearby handball alley adds a touch of contemporary community life to the historic setting.
