Description - Carn Llechart is one of the largest ring cairns in Wales. The circle is 12m (40ft) in diameter, and the central cist has its east side stone and capstone missing. It seems that there is no entry to the circle and no trace of covering mound.

It is an unusual circle of 25 stones leaning slightly outwards and surrounding a central burial cist. Aubrey Burl in his "The Stone Circles of British Isles" wrote that such rings were thought to be the first stage of development of stone circles, but that these cairns, however, are almost certainly too late to provide such an ancestry. The reverse seems likely, that the existence of stone circles elsewhere impelled people to place tall stones around the bases of their own round cairns, a fusion of traditions resulting in monuments like spiky coronets.

Similar cairns may be seen on North and South Uist, and in Wales at Carn Llechart and Bryn Cader Faner.
