Beaghmore Stone Circles

Overview

Beaghmore Stone Circles sit on a rolling expanse of heather‑clad moorland, just 8.5 miles north‑west of Cookstown in County Tyrone. The complex consists of seven stone circles, ten rows of standing stones and twelve burial cairns, all carefully positioned among the grass and peat. The name Beaghmore (Irish Bheitheach Mhór) translates to “big place of birch trees”, a reminder that the area was once a dense woodland before Neolithic farmers cleared it for agriculture.

The circles dominate a landscape that lies at the foot of the Sperrin Mountains, an area noted for its low light‑pollution and spectacular night skies.

Discovery & Management

The site was uncovered in the late 1930s when peat‑cutter George Barnett struck a stone while working the bog. Later accounts note the discovery took place during peat cutting in the 1940s. Subsequent excavations revealed a total of 1,269 stones. The site is now cared for by the Northern Ireland Environment Agency, which maintains the interpretive panels and the modest on‑site car park. It is listed as a State Care Historic Monument (SM number TYR 020:004) and appears on the Historic Environment Map Viewer (grid reference H6846084240). The Department for Communities provides the official contact phone 028 9082 3207 and the visitor website https://discovernorthernireland.com/things-to-do/beaghmore-stone-circles-p675781.

History

Archaeologists believe the stone circles and alignments were erected over several centuries, spanning the late Neolithic into the early Bronze Age. Hearths and flint tools dated to 2900‑2600 BC show that the area was occupied long before the monuments were built. Some of the stone rows cut across the remains of ancient field walls, indicating a continuity of settlement and land use.

A distinctive feature of the complex is the interior of one single circle, which is packed with more than 800 tiny upright stones – often called the “dragon’s teeth”. This dense stone fill sets that circle apart from the paired circles, whose stones are slightly larger but lack the interior fill.

The circles may have served astronomical purposes. Three of the rows align with the midsummer sunrise, while another points toward a lunar maximum, suggesting the builders used the stones as a calendar to track solar and lunar events. A few stones bear chisel marks that resemble early Ogham script, though their meaning remains uncertain.

Archaeological Significance

• Stone count: 1,269 stones in total, including the 800‑plus “dragon’s teeth” within the single circle.
• Burial cairns: Twelve round cairns, some containing human remains, likely used for ritual deposition.
• Pre‑ceremonial landscape: Irregular stone lines and boulder heaps that resemble ancient field boundaries, possibly predating the circles.
• Artefacts: Hearths, charcoal and flint tools dated to 2900‑2600 BC, indicating earlier Neolithic activity.
• Ogham‑like markings: Several stones display incised lines reminiscent of the early Irish alphabet, linking the site to later historic literacy.

These findings suggest a long‑term sacred landscape that evolved from early farming activity to Bronze‑Age ceremonial use.

Legends & Mysteries

Local folklore adds an extra layer of intrigue. The interior “dragon’s teeth” have inspired stories of ancient guardians, while the Ogham‑like markings are sometimes linked to early Celtic writing. In recent years, the Sperrin foothills have become home to a series of giant troll sculptures created by Danish artist Thomas Dambo as part of his “Trail of 1000 Trolls” project – one of which stands beside the OM Dark Sky Park in Davagh Forest.

A curious scientific footnote is the discovery that Mid‑Ulster has a higher prevalence of the so‑called “giant gene” (AIP), a genetic trait that can cause unusually tall stature. Some locals enjoy the coincidence of ancient stone circles, modern troll sculptures and the “giant hotspot” narrative.

Astronomy & Dark Skies

Beaghmore’s remote position makes it one of Northern Ireland’s premier dark‑sky sites. Just a few miles away, Davagh Forest hosts the OM Dark Sky Park & Observatory, opened in 2020 as the country’s first International Dark Sky Park. The park’s name references the ancient Ogham alphabet (OM) and the universal “Om” sound.

During the summer solstice, the sunrise aligns perfectly with three of the stone rows, creating a striking light display that local historians and tour guide Hugh McCloy use to illustrate the ancient astronomers’ skill. The same clear skies that welcomed Neolithic sky‑watchers now offer modern visitors a chance to see the Milky Way in vivid detail.

Guided solstice walks are occasionally organised by Mid Ulster Council and local heritage groups; checking the council’s events calendar in advance is advisable.

Guided Walks and Events

• Summer Solstice Walks – Run by local historian Hugh McCloy and Mid Ulster Council, these guided tours coincide with the sunrise alignment and include commentary on the archaeological and astronomical significance.
• Heritage Open Days – Occasionally the site participates in regional heritage festivals, offering talks and family‑friendly activities.
• Stargazing Evenings – In partnership with the OM Dark Sky Park, informal night‑time gatherings are held during the darker months, allowing visitors to combine the ancient stones with modern astronomy.

Flora, Fauna & Photography

The heather‑clad moor bursts into purple during late summer, while golden grasses dominate in autumn. Birdwatchers may spot meadow pipits, skylarks and occasional raptors soaring over the Sperrins. The open landscape offers unobstructed horizons, making it ideal for wide‑angle landscape shots and night‑sky photography.

Practical Information

Visiting Tips

• Footwear: Sturdy, waterproof shoes are essential – the ground is uneven and can be boggy after rain.
• Weather: The Sperrin area can be changeable; bring layers and a wind‑proof jacket.
• Timing: Arrive early for sunrise during the solstice, or after dark for stargazing. Mid‑day visits can be bright but lack the dramatic light effects.
• Check access: Occasionally the site is closed for conservation work; verify opening status on the official website before you travel.
• Picnic: There are no on‑site facilities, so pack a snack and water.

Getting There

Beaghmore lies on Blackrock Road (B160), Cookstown (BT80 9PA). The most convenient way to reach the circles is by car; the free parking area is just off the road. From Cookstown town centre, follow the A29 north‑west to the junction with Blackrock Road and continue for about 3 miles (5 km). Signposts mark the site.

Public transport is limited. Local buses serve Cookstown; from there a taxi can complete the short journey. Walking from Cookstown is possible but involves a 5 km stretch of road and uneven terrain, so sturdy shoes are essential.

Nearby Attractions

• Davagh Forest – Northern Ireland’s only International Dark Sky Park and home to the OM Observatory.
• Bessy Bell – A popular summit walk in the Sperrin range offering panoramic views.
• Knockmany Passage Grave – A Neolithic burial monument worth a detour.
• Glenelly Valley – The longest Sperrin valley, ideal for scenic drives and walks.
• Gortin Glen Forest Park – A coniferous forest park with marked trails, wildlife and picnic areas.
• Aghascrebagh Ogham Stone – Another example of early Irish script a short drive away.

Seasonal Notes

The site is especially atmospheric during the summer solstice when the sunrise aligns with the stone rows, creating a vivid play of light across the circles. Autumn brings a carpet of heather and golden grasses, enhancing the mystical ambience. After dark, the proximity to Davagh Forest makes the area ideal for stargazing under minimal light pollution.

Beaghmore Stone Circles remain one of Northern Ireland’s most enigmatic prehistoric landscapes. Whether you are a history enthusiast, an amateur astronomer, or simply a traveller seeking a quiet spot to reflect, the stones invite you to step back in time and share the sky with the people who first marked it.
