What is "erdeven"

Erdeven (An Ardeven in Breton) is a commune in the Morbihan department in the region of Brittany in north-western France.

Its main industry is tourism. Attractions include a seven kilometre-long beach beside the Atlantic and many prehistoric sites featuring megaliths. The Mané-Croch, Mané-Bras and Crucuno dolmens and the Kerzerho alignments lie just outside the commune.
