Cosquer Cave

The Cosquer Cave is located in the Calanque de Morgiou in Marseille, France, near Cap Morgiou. The entrance to the cave is located 37 m underwater, due to the Holocene sea level rise. The cave contains various prehistoric rock art engravings. Its submarine entrance was discovered in 1985 by Henri Cosquer, a professional diver. The underwater passage leading to the cave was progressively explored until 1990 by cave divers without the divers being aware of the archaeological character of the cave. It is only in the last period of the progressive underwater explorations that the cave divers emerged in the non-submerged part of the cave. The prehistoric paintings were not immediately discovered by the divers to first emerge from the other side of the sump. The cave was named after Henri Cosquer, when its existence was made public in 1991, after three divers became lost in the cave and died.
