Ireland's hilltop cairns are among its most conspicuous monuments. Many of the great cairns are Neolithic passage tombs, built around 3000 BCE on hilltops: Heapstown Cairn in County Sligo is believed to cover a passage tomb and sits near the Carrowkeel cemetery, and Queen Maeve's Cairn on the summit of Knocknarea, about 55 metres across and 10 metres high, is the largest cairn in Ireland outside Brú na Bóinne. The latter has not been excavated, but its flat top and kerbstones are typical of a passage tomb. Further down this page, About this kind of monument gives the whole of “Irish cairns and barrows”.

The Atlas shows 3700 BCE to 2900 BCE for this site, but that is a regional estimate for this kind of monument, not a date for this particular megalithic mound. No excavation, radiocarbon sample or other measurement is recorded for it, so the real age could fall anywhere within the range, or outside it.
The range rests on this regional background (source: the Wikipedia article “Megalith”): Megalithic construction in Ireland is placed at c. 3700 BC (Knockiveagh) and c. 3400 BC at Newgrange; court cairns continued to be built and enlarged until 2900 BC.

Tradition and region
About this kind of monument
Irish cairns and barrows
Ireland's hilltop cairns are among its most conspicuous monuments. Many of the great cairns are Neolithic passage tombs, built around 3000 BCE on hilltops: Heapstown Cairn in County Sligo is believed to cover a passage tomb and sits near the Carrowkeel cemetery, and Queen Maeve's Cairn on the summit of Knocknarea, about 55 metres across and 10 metres high, is the largest cairn in Ireland outside Brú na Bóinne. The latter has not been excavated, but its flat top and kerbstones are typical of a passage tomb.
Many cairns have not been excavated, and the large ones are dated by comparison with excavated passage tombs.
Folklore is rich. Medieval tales say that Heapstown Cairn is Carn Ochtriallach, built when the Fomorians filled a well of healing with stones in the story of the Second Battle of Moytura, and another tale makes it the burial mound of the prince Ailill. Knocknarea is Miosgán Meadhbha, Meadhbh's heap. In Ireland it is traditional to carry a stone up from the bottom of a hill to add to a cairn, and a Scottish Gaelic blessing says "I'll put a stone on your cairn". These are traditions, not evidence of who is buried.
When visiting, look for cairns on summits, for kerbstones at the base, and for the dip left by antiquarian digging. Visitor erosion of Maeve's Cairn has caused concern, so please keep to the paths.
