Overview
The reason to stop at Clonkeen is the doorway. The church itself is a plain roofless rectangle, 14.6m by 5.5m, tucked into a graveyard on the R506 between Annacotty and Murroe – but built into its west gable is a three-order Romanesque arch carved around 1158, chevron-moulded and still fringed with weathered human and animal heads. It is a National Monument in the care of the Office of Public Works, unguided and free, and you can walk in whenever you like.
If you have twenty minutes, give them to the west gable. The rest of the ruin is quickly read.
The doorway and the building
The innermost order is plain square jambs; the middle order carries octagonal shafts topped with carved leaf capitals; the outer arch is the chevron band, with the heads framing the whole. They’ve taken eight and a half centuries of Limerick weather, so the detail is soft now, but it reads clearly enough in low light. The same west-front Romanesque work is often compared to Aghadoe Cathedral in County Kerry, built in the same decade.
A monastery stood here long before any of this – the foundation is traditionally credited to St Mo-Diomog in the 6th or 7th century – but nothing of that survives above ground. The standing church is mid-12th-century, later remodelled: the Gothic windows in the east and south walls, and the limestone patched in among the original sandstone, point to 15th-century work. It was a ruin by 1657 and has been one ever since.
The graveyard
This is not a sealed-off archaeological site. The grounds are still an active burial ground, used by local families, so old leaning headstones sit alongside new polished ones. Keep to the worn paths, keep dogs on a lead, and don’t climb on the ruin or shift any stones.
Getting there and nearby
The church is signposted off the R506 about 12km north of Limerick City, between Annacotty and Murroe. There is room to pull in, but the lay-by is narrow and the R506 carries fast traffic – the one real hazard here. Cross with care, and wear flat shoes: the ground inside is grass and loose stone, slippery after rain, and the low door threshold catches people out. There are no facilities, seating or staff.
Murroe village is a few kilometres further along the same road. For a fuller day, Lough Gur is about 14km south, Adare Castle 24km west, and Askeaton Castle 35km west.
