The site was excavated in 1881, and it is thought that a sword or small dagger was found. The circle may, in fact, be a curbed cairn, now filled in with earth.
The name Buaile Riabhach is something of a misnomer; that name applies to the fields where the stone circle is found, and the stone circle itself has no known local name.
It's rather hard to know how to describe Buaile Riabhach. Is it a stone circle, a cairn with the addition of standing stones, or a standing stone? Or maybe a bit of each? The location is wonderful, though, with views south to Scalasaig.
Getting There
From the parking area on the B8086 just past opposite the Colonsay Hotel, walk up the hotel drive as if heading for the bar but take the track to the left of the bar and follow it past Island Lodges and a couple of houses until you reach another track. This is the Old Road, leading north to Kiloran. Turn right onto the Old Road. The road begins to climb and you see the stone circle on the right after about 300m.
