Stone circles, stone rows, standing stones, hut circles and cairns.
This section brings together the prehistoric features encountered on my Dartmoor walks.

A line of weathered granite stones stretches across Stalldown in southern Dartmoor, with particularly impressive pillars near its northern end. The row and nearby cairns offer a glimpse of the moor’s prehistoric ceremonial landscape.
| Detail | Information |
|---|---|
| Location | Stalldown, Cornwood parish, southern Dartmoor |
| Grid reference | SX 63240 62346 (Historic England monument reference point) |

A place of ceremony
The association with burial cairns suggests a ceremonial or ritual role, although its precise purpose is unknown. Many stones were re-erected during earlier restoration, so their present positions may not exactly reproduce the original arrangement.

🕰️ When & Who
Built over centuries between 2500 BC and 1000 BC — from the late Neolithic deep into the Bronze Age. This wasn't the work of one tribe or one generation — it was a living, sacred landscape, added to and tended for 1,500+ years.
People lived here too — over 50 roundhouses once stood nearby, with families farming cattle and sheep, lighting hearths, and knapping flint tools right beside the stones. Then around 800–700 BC, things changed — land became over-farmed, forests cleared, the soil tired. People moved away, and the moor reclaimed its own.
🪨 The Stone Rows
There are three rows here — two double, one single:
- North Double Row — 182m long, ~170 stones, runs almost perfectly east–west
- South Double Row — longer still at 264m, over 200 stones, ending at a large blocking stone
- Short Single Row — just 43m, striking off southwest toward the circle
Stones are mostly low — under 1m high — but that's how they were made. They're not grand monoliths for show; they're lines of power, processional ways, maps in stone. Some think they aligned with sunrise/sunset at key times — solstices, planting, harvesting.
⬆️ The Standing Stone (Menhir)
Near the stone circle stands the main pillar — ~3–3.8m (10–12ft) tall, granite, weathered by 3,000+ Dartmoor storms. It's not alone — a smaller stone once stood beside it, re-erected in 1895 but fell again. Between them: a burial barrow, so these stones watched over the dead as well as the living.
❓ What Was It All For?
The honest answer: we don't know for certain. But we can piece it together:
- ✅ Ceremonial processions walking the rows toward the circle
- ✅ Burials & ancestor rites — cairns and kistvaens mark the route
- ✅ Timekeeping — alignments with sun, moon, stars
- ✅ Territory — a sacred landmark visible across the moor
⚠️ Later Years & Loss
The site survived mostly intact until the 1800s. In 1860, the capstone from a burial cist was split and carted off to be a gatepost. Other stones were taken for walls and field drains. Victorians began “restoring” some in the 1890s — work that was well-meaning but uneven. Today it's protected and cared for, but every stone still bears the marks of time.
🚶 John's Take
Merrivale isn't the biggest or most famous site on Dartmoor — but it's one of the most human. You can walk where families lived 4,000 years ago, trace lines they laid by hand, and stand beside a pillar they raised to the sky. The wind, the rain, the wide-open moor — it's all exactly as they would have known it.
