In 1985, a professional diver exploring the Calanques found a submerged prehistoric cave hidden for millennia

An astonishing underwater cave, discovered by diver Henri Cosquer in 1985 off the French Riviera, reveals over 500 Palaeolithic artworks dating back 19,000-27,000 years. These ancient paintings and engravings depict Ice Age animals, including unique maritime life, and hand stencils, offering a profound glimpse into early human expression. Rising sea levels now threaten this invaluable heritage.
