Brittany (4): Gulf of Morbihan

During the Neolithic, what is now the Gulf of Morbihan - a large bay embraced by inward curving arms - was dry land, marsh, hills (now islands) and rivers.

On one of the islands is a protected chamber tomb with rock art. On another is a half-drowned stone circle, built on the side of what was a hill. Now some stones are still standing on the island, some have their tops showing above the water, and some are now wholly under water.
