Poulnabrone dolmen (Poll na mBrón in Irish. As quern translates as bró in Irish, it may originate as "Hole of the quern-stones") is an unusually large dolmen or portal tomb located in the Burren, County Clare, Ireland. Situated on one of the most desolate and highest points of the region, it comprises three standing portal stones supporting a horizontal capstone, and dates to the Neolithic period, probably between 4200 BC and 2900 BC. It the best known and most widely photographed of the approximately 172 dolmens in Ireland.

Its karst limestone setting was formed around 350 million years ago. It was built by neolithic farmers who choose the location either for ritual, as a territorial marker, or as a collective burial site, What remains today is only the "stone skeleton" of the original monument; originally it would have been covered with soil, and its flagstone capped by a cairn.

When the site was excavated in 1986 and again in 1988, around 33 human remains, including those of adults, children (and the remains of a much later bronze age infant) were found buried underneath it, along with various stone and bone objects that would have been placed with them at the time of interment. Both the human remains and the burial objects date to between 3800 BC and 3200 BC.


Poulnabrone is translated from Poll na mBrón in Irish."Brone" is derived from the Irish bró, meaning quern, and the name may originate as "Hole of the quern-stones". It is sometimes wrongly translated as "Hole of Sorrows".[2]

Location and purpose[edit]

Poulnabrone dolmen is situated in a rocky and unblemished field in the remote and high altitude townland of Poulnabrone, Kilcorney, close to the R480 road, 8 km south of Ballyvaughan, in what is now a national park.[3]

It is located on an imposingly high and difficult to access altitude, and was probably used a centre for ritual until well into the Bronze Age period, with evidence that it was in use even into the early medieval Celtic era. It may have served as either a territorial marker in the Neolithic landscape, or as an access point to the important north-south route from Ballyvaughan bay to Kilnaboy.[4] It is possible that the inhabitants of the settlements near Kilnaboy erected the structure to delimit the northern border of their territory.[5]


Poulnabrone dolmen

Poulnabrone is the largest Irish portal tomb after Brownshill Dolmen in County Carlow. It is located on the remains of a mound, and consists of slab-like tabular capstone which is thirteen-feet in length, 2 metres (6 ft) to 3 meters (10 ft) wide and 30 cm (1 ft) thick. Unusually for dolmens of this type, the capstone slopes towards the west.[6] (the chamber's "roof") supported by two sets of slender upright parallel portal stones and orthostats, each 5 to 7 feet high,[6] which mark the entrance, and support the capstone from the ground, creating a chamber that tapers eastwards. Its cairn, which on average extends for 3 meters from the chamber.[7]

The upright stones stabilize the chamber and, as they are placed directly on the limestone bedrock, would have been no higher during the Neolithic period.[3] The entrance faces north and is crossed by a low sill stone, which is positioned east-west crevice. Three stones just before the sill stone form an antechamber backfilled with earth and stones.[7]

Radiocarbon dating indicates that the tomb was likely in use as a burial site between 3,800 and 3,200 BC. The findings are now at the Clare Museum, Ennis, loaned from the National Museum of Ireland.[4][8]

A spiral crack on the eastern portal stone was discovered by a local member of the local public in 1985.[7] As the crack was thought likely to destabilise the tomb, two phases of conservation were undertaken, both overseen by Dr. Ann Lynch, Senior Irish Government Archaeologist at the National Monuments Service.[9] The dolmen was dismantled and the cracked stone replaced during excavations in 1986 and 1988.

Human remains[edit]

During the digs, the remains of around 33 people were found buried underneath the monument. All but one of the adults under the age of 30. They were established as having lived between 3800-3200 BC, and because the ground did not become an on-going burial site over millennia, they can be assumed as members of a specific elite.[4] Personal items buried with them included a polished stone axe, jewelry in the form of bone pendants and quartz crystals, as well as weapons and pottery.[4][10]

There were no intact skeletons, indicating the site was not intended as an ongoing burial place, in the sense that bodies were placed there immediately after or even close to the time of death. Bones were found in the original strata, but were jumbled chronologically, rather than having been buried sequentially. None of the skeletons were intact,[4] and it was often difficult, or impossible, to distinguish the remains of each individual, or establish their sex. Only one adult seems to have lived past 40,[11] many of the bones showed signs of arthritis in the upper body and the children's teeth evidenced illness and malnutrition. In most cases, the pathology and physical condition of the remains indicated lives spent in hard physical labour, and a life-span that ended before the age of 30. Two of the bodies contain major injuries: a skull and rib cage with depressed fractures, healed before death, and an adult male hip bone, pierced by the tip of a stone projectile and not healed, which means the injury occurred not much before the time of death.[11]

Those selected for final interment at this site were apparently the members of some sort of elite. Their bodies had been left elsewhere to decompose, in a protected location, as none of the bones show any signs of teeth marks. Only the bare bones were then taken here and deposited. As some of them show scorch marks, they may have been ritually purified by fire beforehand.[12]

During the Bronze Age (c. 1750 to 1420 BC), a newborn baby was buried in the portico, just outside the entrance.[5]

Tourism and preservation[edit]

The site is relatively unblemished, despite being a popular tourist attraction with a car park. A rope provides a barrier between tourists and the dolmen in order to preserve the ancient stone and it is requested that tourists do not go beyond this barrier or touch the dolmen.

A large car park was opened in 2007 by the Clare County Council to deal with traffic problems caused by cars or coaches parked in the narrow road, due to a 2005 estimate that put the number of annual visitors at 200,000.[13] In 2007, tension arose when Dr. Ann Lynch, the archaeologist who led the excavation of the site, requested that visitor facilities were reduced in order to preserved "the spiritual quality of the landscape surrounding the tomb."[14]
