Tumulus of Bougon

The Tumulus of Bougon is a group of five Neolithic barrows in Nouvelle-Aquitaine, France, constructed over 1,200 years from 4700 to 3500 BC, representing one of the oldest known examples of megalithic architecture on the Atlantic coast of France. Tumulus A contained 220 skeletons and grave goods beneath a 90-tonne capstone. Tumulus F, the longest at 72 meters, features a 32-tonne megalith. Each barrow displays distinct architectural designs with chambers, passages, and stepped mounds. Discovered in 1840, the site is now open to the public with an adjacent museum displaying the archaeological finds.
