This Neolithic chambered cairn occupies a conspicuous position on a low hill overlooking Garrabost. Erected at around 4,000 BC Much of the cairn material has been lost, and it grassed over, but it clearly was almost square in plan, measuring some 19 metres across. It appears to have had a slightly concave stone facade creating a forecourt on its south-eastern side. The passage way, equally, faces south-east, towards the midwinter sunrise which can be seen rising dramatically from the hills of mainland Scotland across the wide expanse of the Minch.
As well as being the focus of religious and ceremonial activities, these were houses of rest for community ancestors.
It is one of the focal points on a waymarked circular walk, 2.2 km long, from Graham Avenue, Garrabost, which also features Clach Ghlas (the Grey Stone), on the banks of the small stream of Allt na Muilne.
There is a small parking space at Graham avenue marking the start of the walk.
