Exploited since 1771, the pink sandstone of the Artzamendi was used to make millstones, slabs, lintels, whetstones, press stones and border makers for instance. Evacuated from the site by ox-drawn carriages, these products were shipped to Cambo les Bains for mills in Bayonne and Dax. The current remains (150 millstones currently listed) concern mainly the Artzamendi mount and Itxassou.
