Historic Sites in County Clare

Most of what survives here is stone left standing on limestone. Poulnabrone Dolmen sits on open pavement in the heart of the Burren, a portal tomb of about 3500 BC whose excavation turned up the bones of at least 33 people; it is free and open all year, and after the Cliffs of Moher it is the busiest thing in the Burren. Corcomroe Abbey, near Bellharbour on the north coast, is the counterweight: a Cistercian church in a green hollow, unstaffed, with carved capitals at the east end that reward a slow look.

The Burren cluster runs on from there. Kilfenora keeps its 12th-century cathedral and high crosses, three of them under glass, and Kilnaboy has a Sheela-na-gig over the south door and the Mullaghmore Loop starting nearby. Killilagh, the parish holding Doolin, has a church burned in 1645 and a court tomb at Teergonean. Dysert O’Dea, further south, carries a Romanesque doorway of nineteen heads beside a round tower Cromwell’s men blasted.

Ennis Friary is the one town site, walkable in the county town and staffed by an OPW guide in season. East Clare is a different county again, Lough Derg and the Shannon rather than the Atlantic, with Holy Island by boat and St Cronan’s at Tuamgraney. That side needs its own day and its own drive.

Poulnabrone Dolmen – Neolithic Burren tomb

Burren, clare

Poulnabrone is a Neolithic portal tomb on the Burren's limestone pavement: a thin capstone tilted west on two tall portal stones, built around 3500 BC. Rescue excavations in the 1980s recovered the bones of at least 33 people, along with a stone axe, arrowheads and beads now in the Clare Museum. It's free, open all year, and the most visited spot in the Burren after the Cliffs of Moher.

Corcomroe Abbey – Burren Cistercian ruin

Near Bellharbour, clare

Corcomroe Abbey is a Cistercian church set in a green hollow of the grey Burren, founded for monks from Inislounaght around 1195 and built in the early 13th century. The carved capitals and ribbed vault at the east end are among the finest medieval stonework in any Irish Cistercian ruin. It is free, unstaffed and open in daylight, near Bellharbour in north Clare.

Kilkerrin Battery – Shannon's lost fort

labasheeda, clare

One of six limestone forts built between 1811 and 1814 to cross-fire any French ships entering the Shannon, Kilkerrin Battery is the best-surviving of the chain. You can walk its dry moat, find the iron pulleys that once raised the drawbridge, and look across Clonderlaw Bay to Kerry. A 2019 survey found protected lesser horseshoe bats roosting inside the blockhouse.

Kilmacreehy Church & Graveyard

Liscannor, clare

The ruined church at Kilmacreehy stands in a graveyard sloping toward Liscannor Bay, about 2 km south-east of the harbour. The 15th-century stonework sits on a site used since at least the 6th century, and the Irish-language poet Aodh Buí Mac Cruitín lies here in an unmarked grave. It is a short roadside stop with one good story attached.

Newmarket-on-Fergus – Mooghaun hill-fort

Newmarket-on-Fergus, clare

In 1854 the largest hoard of prehistoric gold ever found in western Europe turned up near Mooghaun Lough, just outside Newmarket-on-Fergus. The gold is in Dublin now, but the great Bronze Age hill-fort above the find is still here - free, unstaffed, open any time - and it is the best reason to stop. Dromoland Castle, a Mid Clare Way trailhead and trout fishing round it out.

St Cronan’s – Brian Boru’s doorway

Tuamgraney, clare

You enter St Cronan’s through the same 10th-century doorway Brian Boru is recorded as repairing around 1012 – and it is still a working church, the oldest in continuous use in Ireland or Britain. Inside are a carved Romanesque head, medieval windows and a €1 million stained-glass Ascension, free to see from April to September.

Questions people ask

Which historic sites in Clare are close enough to do in one day?
The Burren group works well together: Poulnabrone Dolmen, Kilfenora with its cathedral and high crosses, Kilnaboy's church, and Corcomroe Abbey near Bellharbour on the north coast. Dysert O'Dea sits a little south of these and pairs naturally with Ennis on the way back.
Are Clare's historic sites free to visit?
Many are. Poulnabrone Dolmen is free and open all year, Corcomroe Abbey is free, unstaffed and open in daylight, and the sites around Killilagh near Doolin are free year-round. Ennis Friary is free to enter and has an OPW guide during the season.
Which one should I choose if I only have time for one?
For prehistory, Poulnabrone Dolmen, the single most recognisable monument in the Burren. For medieval stonework, Ennis Friary, since the carvings sit under a modern roof and there is a guide in season. Corcomroe Abbey suits anyone who would rather have a ruin to themselves.
What is there in east Clare, away from the Burren?
East Clare faces Lough Derg and the Shannon instead of the Atlantic. St Cronan's at Tuamgraney is reckoned the oldest church in continuous use in Ireland or Britain, free to see from April to September, and a boat runs to the monastic ruins on Holy Island.
Can I visit these sites in winter?
The unstaffed ruins stay open: Poulnabrone, Corcomroe, Mooghaun hill-fort at Newmarket-on-Fergus and the Killilagh sites have no gate or season. Staffed and seasonal access is the exception, with St Cronan's open April to September and Ennis Friary guided in season only.
