#297 Revisited: A Deep Dive Into the Past

Engineering Matters

In 1985 diver Henri Cosquer discovered a submerged cave entrance in the Mediterranean near Marseilles. Exploring over the next six years he discovered a chamber filled with prehistoric art.

Conditions in the caves and the submerged passages leading to it are extremely dangerous: three divers lost their lives exploring the caves.

Efforts to map the cave structure using traditional techniques proved impossible, but with modern 3D scanning and photogrammetry tools, replicas of key works from the cave have been created on land, spreading knowledge of the caves to future generations.
