The Cosquer cave is located in the Calanque de Morgiou in Marseille, France, not very far from Cap Morgiou. The entrance to the cave is located 37 m (121 ft) underwater, due to the rise of the Mediterranean in Paleolithic times. It was discovered by diver Henri Cosquer in 1985, but its contents were not made public until 1991, when three divers became lost in the cave and died.
