Neanderthal cave mystery

A teenage potholer discovered a cave system near the town of Bruniquel in France in 1990 which contained a mysterious circular structure. It turned out to be nearly 200,000 years old, and built by Neanderthals – transforming our understanding of Neanderthal culture and society. Lucy Burns speaks to Bruno Kowalczewski, who discovered the cave, and geologist Sophie Verheyden, who was part of the research project which discovered the structure’s incredible age.
