An eliptical setting (about twenty-one metres by ninteen metres) of five large stones just a few hundred metres from Calanais I. The tallest stone is nearly three and a half metres in height.
Originally this was a ring of ten stones with an eleventh outlier. A cairn, eight and a half metres in diameter, was built in the circle a little to the east of centre.
Post-hole evidence suggests that, before the stones were erected, there was a timber circle on this site; this would have been about ten metres in diameter.
