Menhirs de Kerderff Menhirs de Kerderff are similar to the The Pipers, St Buryan, but are in the area of Brittany where the Alignements du Vieux-Moulin, Carnac and Gravinis are located.

Menhirs de Kerderff They are two separate stones separated by 50m with a height of 3m and 5.8m. Like many of these stones, they had been worked to give a slightly pointed shape. Assuming these two stones were east/west when built, then a date can be derived from the angle. They are currently at 9° east/west.
