Collections of bear bones at several widely dispersed sites suggest that Neanderthals may have worshiped cave bears, especially at Drachenloch above Vättis, in Switzerland, where a stone chest was discovered with a number of bear skulls stacked upon it.

Neanderthals, who also inhabited the entrance of the cave, are believed to have built it.

A massive stone slab covered the top of the structure.

At the cave entrance, seven bear skulls were arranged with their muzzles facing the cave entrance, while deeper in the cave, a further six bear skulls were lodged in niches along the wall.

Next to these remains were bundles of limb bones belonging to different bears.
