Machrie Moor Stone Circles, Isle of Arran

Machrie Moor Stone Circles, Isle of Arran: Six Circles on a Wild Moor

Overview

On the west side of the Isle of Arran, a boggy moor runs back from the sea towards the granite peaks of the island’s north. Scattered across it are the Machrie Moor stone circles — not one monument but six, together with the buried traces of others — one of the richest concentrations of prehistoric circles anywhere in Scotland. Some are dramatic rings of tall red sandstone pillars; others are low, humble settings of granite boulders. Reaching them takes a walk of about an hour there and back, and that effort is part of the magic: you come upon them slowly, across empty moorland, exactly as people have for four thousand years.

What you’re looking at

  • Six stone circles spread across the moor, ranging from tall monoliths to low boulder rings.
  • The showpiece (Circle 2) is a ring that once held tall slender sandstone pillars; the survivors stand up to about 5.5 metres — among the most striking standing stones on any Scottish island.
  • Other circles are rings of squat granite boulders, quite different in character — showing that these were built and rebuilt over a long span, in changing styles.
  • Beneath and around the visible stones lie the postholes of earlier timber circles, and Historic Environment Scotland has even detected a further buried circle in recent years.

The full history

Machrie Moor tells a story of continuity stretching across two thousand years. Activity here began in the Neolithic, around 3500 BC, with pits and early features; timber circles were raised around 2500 BC; and the stone circles you see today were built around 2000 BC — crucially, set directly on the sites of the earlier timber ones. In other words, generation after generation returned to the exact same sacred spots and remade them in more permanent form. Excavation revealed those timber predecessors beneath the stone settings, along with traces of the farming community that lived and worshipped here. It is a whole ceremonial landscape, not a single ring.

Fingal’s Cauldron Seat

One of the granite circles contains a stone with a hole worn through it, known as Fingal’s Cauldron Seat. Legend says the giant-hero Fingal (Fionn mac Cumhaill) rested here and tethered his dog Bran to the holed stone while his cooking-pot bubbled — one of many places across the Gaelic world where the old hero left his mark on the land.

Seeing them

The circles lie inland from the A841 on Arran’s west coast, a few miles north of Blackwaterfoot; the island’s ferry port is Brodick (CalMac from Ardrossan). Access is free and open, cared for by Historic Environment Scotland, but note it is a walk of roughly 1.5 miles each way along the Moss Farm Road track from the roadside car park — flat but often muddy, so wear boots. Allow a couple of hours to do the moor justice, and pick a clear day: the circles set against Arran’s mountains are the whole point.
