Submerged wells and caves

Underwater cultural heritage also encompasses artefacts and traces of ancient human life preserved in flooded caves, which either have always been submerged or have been flooded by the rise of the sea.

Such sites include, for instance:

  • the French Cosquer Cave, with its entry at a depth of 37 meters under water, featuring  paintings and engravings made between 27,000 and 19,000 years ago. While the entry of the cave lies deep under water, the paintings themselves are not submerged;
  • the Chichen Itza Cenote in Mexico (karst cave tunnelled into the limestone by groundwater).  The use of this cenote was exclusively sacrificial and ceremonial and remains of human sacrifices have been found.
