Poulnabrone dolmen: the Burren's 5,000-year-old portal tomb

Poulnabrone dolmen is a Neolithic tomb on the limestone of the Burren in County Clare. It’s a portal tomb: two tall stones at the front and side stones behind, holding up a single tilted capstone, standing on bare limestone pavement. It was excavated in the 1980s with modern methods, so we know a surprising amount about the people buried in it. Below: how old Poulnabrone dolmen is, who was buried there, what the name means, the stories attached to tombs like it, and how to visit without the coach crowd.

Where is Poulnabrone dolmen?

Poulnabrone is in the townland of Kilcorney, in the high central part of the Burren in north-west County Clare. Heritage Ireland describes it as standing at one of the highest points of the Burren. It sits beside the R480, the road that runs north–south through the Burren between Ballyvaughan and Leamaneh Castle.

It’s about 8 km south of Ballyvaughan, and a few minutes’ drive from Caherconnell stone fort. Doolin and the Cliffs of Moher are further south-west, beyond Lisdoonvarna.

How old is Poulnabrone?

Radiocarbon dates from the bones show the tomb was used for burial between about 3800 and 3200 BC, in the early Neolithic. That makes it more than 5,000 years old. To put that in perspective: people were already being buried here centuries before the great stone circle went up at Stonehenge.

The tomb was then used again, much later. An infant was buried just outside the entrance in the Early Bronze Age, between about 1750 and 1420 BC.

What the excavation found

In the 1950s a survey spotted a crack in the eastern portal stone, and by the early 1980s it looked likely to bring the whole tomb down. Ann Lynch, Senior Archaeologist at the National Monuments Service, led conservation and excavation work in 1986 and 1988. During the 1986 work the capstone was raised on a wooden scaffold to take the pressure off the cracked stone. (So the reason we know so much is that it nearly fell over.)

What she found, according to Heritage Ireland and the published summary on Wikipedia:

The people

• The remains of about 33 people. The detailed bone count gives a minimum of 28, and more likely about 36.
• At least 17 were adolescents or younger.
• Wear on the teeth points to a coarse, mostly plant-based diet with little meat.
• One young or middle-aged man had a healed, oval dent in his skull, possibly from a sling stone.
• Another person had the tip of a triangular stone arrowhead lodged in the right hip bone, probably shot from behind.

The objects

• A polished stone axe
• A bone pendant and part of a mushroom-headed bone pin
• Two stone disc beads
• Two large quartz crystals
• Flint and chert scrapers and arrowheads
• About 60 shards of coarse pottery

Lynch published the full report in 2014, if you want the detail.

How Poulnabrone was built

Part	Size
Capstone	About 3.9 m long, 2–3 m wide, 0.3 m thick
Chamber	About 2.8 m long, narrowing to the east
Surviving cairn	Extends an average of about 3 m from the chamber

The side stones stand directly on the bedrock. The capstone slopes upward toward the west. A low cairn of stones once surrounded the chamber, and the whole tomb was probably covered with soil. Only the stone frame and part of the cairn are left. A large slab lying behind the tomb may have been a second capstone.

That’s the part most photos don’t tell you: what you see is the skeleton of the tomb, not how it looked when it was in use.

Poulnabrone dolmen in Ireland’s family of portal tombs

Ireland has about 172 recorded dolmens, spread across the island. The basic plan is the same: tall portal stones forming an entrance, side stones making a chamber, and one heavy capstone laid across the top. Two things make Poulnabrone stand out. It stands on bare limestone, so the whole structure is visible against the sky from a distance. And it’s been excavated with modern methods and radiocarbon dating, so we know roughly when it was used, how many people were placed in it, what they ate and how some of them were hurt. At Poulnabrone the portal stones are at the lower, eastern end, and the capstone rises toward the west.

What does Poulnabrone mean?

The name comes from the Irish Poll na Brón. The usual translation is “hole of the quernstone,” a quern being a hand-mill for grinding grain. You’ll also see “hole of sorrows,” because brón can also mean sorrow in Irish. Guess which one the postcards prefer.

Poulnabrone in myth and story

Portal tombs and wedge tombs are part of the old story-landscape of Ireland, and people have told stories about them for a long time.

Diarmuid and Gráinne’s beds. In the medieval tale The Pursuit of Diarmuid and Gráinne, Gráinne, promised to the aging Fionn mac Cumhaill, runs away with Fionn’s young warrior Diarmuid. They’re chased across Ireland and sleep somewhere different every night. Across Ireland, many flat-roofed Neolithic monuments, including dolmens and wedge tombs, carry the local name “Diarmuid and Gráinne’s Bed” (Leaba Dhiarmada agus Ghráinne). You’ll see websites attach that name to Poulnabrone. We couldn’t find any local record calling Poulnabrone by that name, so treat it as a general tradition about tombs like this one, not a fact about this one.

The old gods in the hills. In Irish myth, the Tuatha Dé Danann went into the hills and ancient mounds and became the Sídhe, the fairy folk. Our guide to fairies in Irish folklore goes further into those beliefs.

How to visit Poulnabrone dolmen

• Access. It’s an unguided outdoor site in the care of the Office of Public Works, and there’s no ticket. Heritage Ireland asks visitors to take care at all times on the uneven ground.
• Parking. Clare County Council opened a car park in 2007 to take cars and coaches off the narrow road. From there it’s a short walk over uneven ground to the tomb.
• The ground. The tomb stands on limestone pavement with deep cracks (grikes). Wear shoes with a good grip, especially when the rock is wet.
• Respect the monument. It’s a protected National Monument. Don’t climb on it, sit on it or move stones. Yes, even for the photo.
• Best time. Early morning or evening is usually quieter than the middle of the day, when the coaches come through. In late June the sun sets after 10pm, so there’s plenty of evening light.
• Combine it. Caherconnell stone fort, which dates back to the 10th century and runs sheepdog demonstrations, is a few minutes away. Aillwee Cave is on the same road, the R480, toward Ballyvaughan.

The Burrenbeo Trust’s Burren Archaeology Festival, held in Ballyvaughan on 20–21 June in 2026, included talks by Dr Ann Lynch, the archaeologist who excavated Poulnabrone. If a future festival falls on your dates, go. It’s not often you can hear about a dig from the person who led it.

Other tombs and monuments in the Burren

Poulnabrone is one of about 70 megalithic tombs in the Burren, and about 90 percent of those are wedge tombs. The region also has almost 500 stone ring forts. Our Burren guide covers the main ones, including Caherconnell, Cahercommaun and Corcomroe Abbey, plus the geology and the June flowers on the pavement around the tomb.

Poulnabrone on our trip

On our Midsummer in the Burren trip in June 2028, Poulnabrone comes after a guided folklore and fairy-fort walk on the Burren, followed by Caherconnell stone fort. By then the group has spent months reading the stories of the Tuatha Dé Danann, so it isn’t just a photo stop.
