This prehistoric archaeological Neolithic site is on the R480 road running north to Ballyvaughan.

The Poulnabrone Portal Dolmen (distant top right) lies on the limestone pavement of The Burren, County Clare. The huge stone in the foreground is a glacial erratic, 'dropped' when the glacier's retreated at the end of the last ice age.

Poulnabrone Dolmen, archaeological site in the Burren: Poulnabrone dolmen stands on a limestone pavement of the Burren hills and must be the most photographed archaeological site in Ireland! In the foreground is a large limestone rock left behind by the last glacier to cover the Burren!

Poulnabrone Dolmen, archaeological site in the Burren: It is a Neolithic ritual-burial site dating from about 2500 BC, i.e. over 4500 years old.

The striking starkness of the Poulnabrone Dolmen, a prehistoric burial tomb. From excavations in the 1980's artefacts such as a polished stone axe, carved quartz crystals, perforated bone pendant, stone disc beads, sherds/fragments of course pottery and flint arrowheads and scrapers were found. The bones of 33 individuals were found of male and female, old and young and were probably put in the tomb around 3000 BC. Burials were radiocarbon dated to 4200 to 2900 BC (Neolithic or New Stone Age) and 1767 to 1423 BC (early Bronze Age).

Poulnabrone Dolmen, archaeological site in the Burren: The remains of about 22-28 people were found in the chamber including six children and the adults were all less than thirty in age.

Poulnabrone Dolmen, archaeological site in the Burren: A number of artefacts were also found in the graves e.g. a polished stone axe, stone disc beads, bone pendant - perforated to hang on 'string', quartz crystals and a fine bone pin.

Poulnabrone Dolmen, archaeological site in the Burren: The dolmen stands on a low circular cairn about 30 feet in diameter.

The top capstone of this famous archaeological site weighs 1.5 tonne.

The typical seemingly barren landscape of the limestone pavements of the Burren. When the Poulnabrone tomb was constructed the landscape was very different. Open pine forests with elm and hazel were common and some areas of open grassland. Today's relatively barren terrain is mainly due to loss of top soil in prehistoric times. These early farmers would have lived in simple wooden houses living off crop cultivation like wheat and barley, domestic cattle together with fishing and hunting of fowl and wild animals. Their simple homesteads and subsistence poverty farming sharply contrasts with their elaborate and 'expensive' tomb building in terms of the physical effort and 'engineering' involved. There is much to be admired from the distant culture of our prehistoric ancestors.

Unearthing prehistoric sites

For example, excavations from 1986–88 found 33 human remains, both adults and children, and even a Bronze Age infant with radiocarbon dates suggesting a range from 3800–3200 BC (citation 1-3). I recall polished stone axes and pottery fragments as grave goods (citing Irish Archaeology for these). It's key I don’t misrepresent details, especially regarding cremated and unburnt remains—both have been documented.

Poulnabrone Portal Tomb — overview and setting

Poulnabrone is a classic Neolithic portal tomb (dolmen) set on the exposed limestone pavement of the Burren, County Clare. The visible monument today consists of two tall portal stones and a rear-stone that support a large, flat capstone; originally the stone chamber was covered by a cairn or mound of stone and soil, of which only a low spread of cairn material now survives.

Structure and architectural details

• Monument type: Portal tomb (single‑chamber dolmen).
• Visible elements: Two upright portal stones at the entrance, a back (or rear) orthostat, and a large horizontal capstone that spans the chamber. The capstone is roughly trapezoidal and narrows from east to west.
• Cairn/setting: Excavation showed the chamber lay within a circular or sub‑circular cairn c. 10 m across; the present exposed stones are the “stone skeleton” of a formerly covered tomb.

Excavations and radiocarbon dating

• Excavations: Systematic archaeological work took place during conservation excavations in 1986 and 1988, published later as a comprehensive site monograph.
• Radiocarbon dates and chronology: Radiocarbon determinations place the main use of Poulnabrone in the early Neolithic (broadly the fourth millennium BC). Published summaries give dates in the early Neolithic (commonly quoted around c. 3800–3500 BC for initial use) with later activity into the later Neolithic and a much later Bronze Age burial identified among the human remains.

Phases of use and burial sequence

• Construction and primary use (Early Neolithic): The tomb was constructed and used as a collective burial place in the early Neolithic. Burials were deposited within the chamber while the monument was a covered cairn, not as the open stone structure seen today.
• Multiple depositional episodes: Excavation evidence indicates repeated interments over time rather than a single burial event. Human remains were recovered in several depositional episodes, including primary interments and later re‑arrangements or re‑depositions of bone within the chamber.
• Later activity (later Neolithic / Bronze Age): The tomb continued to receive some attention long after its initial construction; at least one much later Bronze Age interment (an infant) was identified among the remains, showing the site was revisited or remained significant for millennia after first use.

Human remains recovered

• Quantity and composition: Excavations recovered the remains of multiple individuals (commonly reported as around 30–33 people), including adults and children, and at least one later Bronze Age infant.
• State of remains: The assemblage included both uncremated (inhumated) and cremated bone. Many skeletons were incomplete and disarticulated, indicating secondary deposition, disturbance, or rearrangement within the chamber over time.
• Demography and trauma: The human sample included males and females and a range of ages; osteological study showed evidence of everyday life and trauma in some individuals (details and interpretations are presented in the excavation monograph).

Grave goods and associated artefacts

• Types of finds: Excavation recovered a small suite of artefacts placed with the dead: worked stone implements (including at least one polished stone axe), flint tools and fragments, pottery sherds, and worked bone pins or needles.
• Context and significance: These objects are consistent with Neolithic mortuary practice in Ireland — a few curated personal items accompanying burials rather than large grave‑furnishing assemblages. The artefacts, together with body treatments (inhumation and cremation, primary and secondary deposition), indicate complex funerary behaviour and long‑term ritual use of the tomb.

Interpretation and significance

Poulnabrone is interpreted as a communal, ritual burial monument that functioned as a focus for Neolithic communities in the Burren landscape. Its repeated use, mixture of primary and secondary deposits, presence of both cremated and uncremated remains, and the occasional inclusion of grave goods all point to long‑lived social and ritual practices centred on collective ancestor deposition and memory in the Neolithic and with episodic re‑use into the Bronze Age.
