Overview

If you only look at one thing here, make it the south-wall doorway. Four carved orders frame nineteen heads – twelve human faces and seven stylised beasts – and there is nothing else quite like it in this part of the Burren. The doorway belongs to a ruined 12th-century church that sits on a low limestone rise just outside Corofin, the core of an early monastic settlement founded, by tradition, by St Tola in the 8th century. It is a National Monument, maintained by the Office of Public Works, and the anchor of the Dysert O’Dea Archaeological Trail. Alongside the church stand a broken round tower and a much-travelled high cross.

One honest warning before you go: the site is poorly signposted, and plenty of visitors miss the turn. It’s about 5 km south of Corofin and 11 km north of Ennis, just off the R476 – watch for it rather than trusting the signs to catch you.

The ruins and architecture

The church is Hiberno-Romanesque, its nave roughly 71 feet long and 24 feet wide, running into a slightly narrower choir of about 25 by 21 feet, with walls some 14 feet high and three feet thick. The doorway is the reason to come: study the outer arch and you can pick out individual faces among the beasts, medieval stonemasonry at close enough range to touch.

East of the church stands what’s left of the round tower. It once rose to around 30 metres, until Cromwellian artillery reduced it in 1651; only about a third survives now, roughly 10 metres, with 16th-century defensive alterations added when the stump was pressed into use as a fortification.

Nearby, St Tola’s high cross rises about 12 feet. The 12th-century cross has had an eventful life. Its east face shows a crucifixion above a bishop carved in relief; Cromwellian troops knocked it over, and Michael O’Dea re-erected it in 1683 using corner stones salvaged from the church, physically welding the two monuments together. The Synge family restored it again in 1871, and in 1960 it was shipped to Barcelona for an exhibition before returning to its field.

History and legend

Tradition places the founding of the hermitage with St Tola in the 8th century, and the site grew into a monastic centre under the local O’Dea clan, whose name it still carries. In 1318 the Battle of Dysert O’Dea was fought nearby – a decisive Gaelic victory that drove Anglo-Norman power out of Thomond for over two centuries.

Spiritual life here centred on St Tola’s Well, a short walk east. The well is pre-Christian in origin and was the focus of an annual pilgrimage on 30 March. It was paved over in the 1860s and only reopened in 1986; the pilgrimage still draws people for a reflective walk and blessing.

What to see and do

  • The doorway and high cross – Bring a camera. The nineteen heads reward slow looking, and the cross’s interlace and figure carving repay a circuit around the base. Interpretive panels in the churchyard explain the symbolism.
  • Walk the archaeological trail – Two routes leave from the site. A 300-metre loop covers the church, high cross, round tower and well – enough if you’re short on time. The longer 5-kilometre circuit passes some two dozen monuments, including ring forts, a fulacht fiadh (a prehistoric cooking site), and the ruins of a 19th-century proselytising school. The trail is open year-round.
  • Combine with O’Dea Castle – The restored 15th-century castle alongside houses the Clare Archaeology Centre, with a museum, bookshop, tearoom, toilets and a rooftop castle walk; the audio-visual presentation runs in English and German. In summer the roof walk gives panoramic views across the Burren and the River Fergus.

Visitor information

  • Opening hours: The castle and its facilities open May to September, daily 10:00 to 17:00. The outdoor archaeological trail and monuments are accessible year-round, but out of season you won’t have the museum, tearoom or toilets.
  • Admission: Adult €6, Child €4, Student/Senior €4, covering the ruins, the trail and the castle museum.
  • Parking: Free on-site parking for cars and coaches.
  • Accessibility: The 300-metre loop is fairly level and manageable for most; the longer circuit has uneven ground and steps. Toilet facilities are not wheelchair accessible, and the ruins limit interior access.

Getting there and nearby stops

From Ennis, follow the N85 to Corofin, then the R476 south, keeping a close eye out for the Dysert O’Dea turn. The drive runs through open Burren countryside with regular views of the River Fergus.

Building a day around medieval Clare, the ruins pair well with a short section of the Burren Way, which passes close by. Clare Abbey has well-preserved Cistercian ruins a short drive off, and Corcomroe Abbey makes a quieter, woodland-set alternative. With children, Aillwee Cave or the reconstructed village at Bunratty round out the day.

Allow at least two hours for the church, cross, tower and well at an easy pace, and an extra hour for the castle museum and roof walk. Wear sturdy footwear – the limestone paths and the tower base are uneven – and check the castle website for summer roof-walk times before you set off.
