Deep inside a dark, underground cave 50 km from the city of Toulouse, France, researchers have uncovered the remains of six ancient structures crafted from stalagmites. The find forces us to rethink our assumptions about these archaic humans, because what they appear to have built is far beyond anything we thought they were capable of.

The ring-shaped structures were found 300 metres deep inside Bruniquel Cave in southwest France, and one is thought to have stood almost 7 metres wide. The twisted corridors of this cave are pitch black this far from the entrance, so the Neanderthals would have had to construct everything by firelight.

At this stage, what isn’t exactly clear is why this community appears to have banded together to achieve this complex, difficult task in an inhospitable environment. If they needed shelter from the elements and protection from predators, they were already inside a deep cave, why go to all the trouble of building a structure within a structure?
