One morning near Montignac four friends were telling stories about treasures hidden in the forest. As they were walking, they found a hole in the ground and decided to explore it for treasures. Unfortunately, but they had not got a torch. So they returned the following day and discovered some paintings on the walls of the underground tunnel. They told their teacher about them. As it turned out later, the paintings were ancient.Experts had examined them paintings and found out that they were about 17 000 years old. As a result the teacher praized the boys and they felt very proud.
