Situated on a low ridge above the waters of Loch Roag with the hills of Great Bernera as a backdrop, three complete circles lie within a few kilometres of each other. Erected in the Neolithic era, the Callanish Stones were a focus for ritual activity during the Bronze Age.
This site, Callanish III, has five rows of standing stones connected to the main circle. Two long rows of stones run almost parallel to each other from the circle to the north-northeast forming a kind of avenue. The stones are all of the same rock type, namely the local Lewisian gneiss. Within the stone circle is a chambered tomb to the east of the central stone.
