Gavrinis

Gavrinis (Breton: Gavriniz) is a small island in the Gulf of Morbihan in Brittany, France. It contains the Gavrinis tomb, a Neolithic passage tomb built around 4200–4000 BC, making it one of the world's oldest surviving buildings. Stones inside the passage and chamber are covered in megalithic art. It is likened to other Neolithic passage tombs such as Barnenez in Brittany and Newgrange in Ireland.
