The Cerne Abbas Giant is a very large picture drawn on a hill in England. It's like a giant drawing that you can only see from high in the sky or from far away. The drawing is of a man who is very big and has no clothes on.
People have been looking at this giant picture for a very long time, and they still don't know for sure who drew it or why. Some people think it might have been made thousands of years ago by people who lived there a long time ago. Other people think it was made more recently by people who just wanted to make something big and interesting.
The picture of the giant is made by carving deep trenches into the grassy hill. The trenches are filled with a white material so that they really stand out against the green grass.
The Cerne Abbas Giant is very special because it is so big and mysterious. It's a very old piece of art that has been around for a very long time, and it's still so interesting to people today.
