Beaghmore Stone Circles
Blackrock Road · County Tyrone · Northern Ireland
Seven low stone circles, ten alignments and twelve cairns lay hidden beneath the Tyrone peat until twentieth-century cutting exposed a ceremonial landscape built over even earlier Neolithic fields.

A whole prehistoric landscape hiding beneath the bog
Beaghmore is not one photogenic ring of giant stones. It is a dense and complicated complex of circles, rows and cairns whose relationship remains uncertain. The peat that eventually swallowed it also protected the low stones until cutters brought them back into view.
At a glance
Visitor details checked 4 September 2026Fields first. Monuments later. Peat over everything.
Excavation uncovered a landscape that changed repeatedly before disappearing.
Farming before ceremony
Hearths and flint deposits point to occupation before the visible monuments. Several later rows cross collapsed field boundaries, suggesting that cultivation and clearance came first.
The ritual complex was built over a landscape that already had a history.Circles, rows and cairns
Seven circles, ten stone rows and twelve cairns were arranged across the site. Six circles form pairs, while rows of differently sized stones stretch towards or away from the monuments.
The structures may combine burial, ceremony, memory and observation rather than serving one purpose.The bog gives them back
Peat cutting revealed the stones, and excavation began during the 1940s before the complex entered state care. Archaeologists recorded 1,269 stones, but further structures may remain beneath surrounding peat.
What survives above ground may still be only part of Beaghmore.Was Beaghmore built to call back the light?
The stone rows tend to radiate roughly north-east, and writers have repeatedly proposed solar, lunar or stellar alignments. The official heritage interpretation raises a particularly haunting possibility: as peat spread and the soil became less productive, monuments may have been raised in an attempt to attract back the fading sun and restore fertility.
It is a powerful idea, but it remains an interpretation. Alignments within a complex containing more than a thousand stones can occur without proving a working observatory, calendar or single astronomical plan.
What can be said safely is that the builders repeatedly selected, moved and arranged stones within a landscape already altered by farming, burial and environmental change. Whatever Beaghmore measured or addressed, it mattered enough to be rebuilt in several forms.
The Dragon’s Teeth and other clues
The smaller details make far more sense once you stop expecting Stonehenge.
The Dragon’s Teeth
One circle is packed with more than 800 small upright stones. The modern nickname captures its appearance, but it does not preserve a known Bronze Age dragon legend.
High and low rows
Short lines of taller stones sometimes sit beside much longer rows of smaller ones. Their direction appears deliberate, though the intended destination or observation remains disputed.
The buried branch
A central pit within the largest cairn contained an oak branch. Without written testimony, it cannot tell us whether it was an offering, marker, construction element or something more ordinary.
Read the pattern, not just the individual stones
This is a compact visit, but rushing from one obvious circle to the car misses what makes the site unusual.
A useful first visit
Walk the whole complex once, then return to the arrangement that bothered you most.
Find the paired circles
Begin by identifying how six circles sit in pairs rather than viewing each as an isolated monument. Cairns and rows repeatedly occupy the spaces between them.
Trace the alignments
Follow the changes between taller and smaller stones and notice where the rows point. Test the astronomical idea against the actual landscape rather than a diagram.
Meet the Dragon’s Teeth
Finish at the densely filled circle. Decide whether it feels like part of the same system or a monument with an entirely different purpose.
Arrival, parking and facilities
Beaghmore lies on remote Blackrock Road, north-west of Cookstown. Mobile reception may be unreliable, so load directions before entering the Sperrins and do not assume the final road will be busy.
Parking: Small free area near the entrance
On site: Interpretation only · no dependable visitor facilities
Best combined with: Davagh Forest and the OM Dark Sky Park area
Terrain and exposure
The monuments occupy rough moorland rather than a surfaced visitor attraction. Conditions can deteriorate quickly after rain and the low stones may be difficult to distinguish in long vegetation.
Build Beaghmore into a larger strange journey
Beaghmore works best as a highly atmospheric detour within a wider route. ParaMaps’ existing destinations lie far enough away to deserve their own substantial stop.

Beaghmore is not dramatic because its stones tower over you. It is dramatic because more than a thousand of them form a plan whose rules have been lost – built over old fields, covered by peat and returned without an explanation.
