Lascaux is a very special place in France where people made cave paintings a long time ago. The paintings were made on the walls and ceilings of the cave using things like rocks, leaves, and even animal hairs. The paintings are really old, over 17,000 years, which is like a million billion sleeps for you!
The paintings at Lascaux are very important because they give us a glimpse of the world thousands of years ago - a world where animals like horses, deer, bison, and bulls roamed around. The people who made these paintings were called 'cave people'. They wanted to tell the story of their lives, so they painted pictures of the animals they hunted, the tools they used, and important events like hunting rituals.
The cave is very dark and damp, which helped to preserve the paintings for so many years. Nowadays, people cannot go inside the cave because visitors' breath can damage the paintings. But people can see the pictures because there are special replicas of the cave that were made, so that everyone can see these amazing and magical paintings!
