La chouette d'or is a treasure hunt in which people try to find a golden owl hidden somewhere in France. The hunt was created by a man named Max Valentin who made a bunch of clues and riddles that people have to solve in order to figure out where the owl is hidden.
The hunt started back in 1993 when Max Valentin published a book with all of the clues in it. People have been trying to solve the puzzles ever since then, but no one has been successful in finding the owl yet.
There have been many theories and ideas about where the owl might be hidden, but no one knows for sure. Some people think it's buried underground, while others think it might be hidden in a tree or a building.
If you want to try and find the chouette d'or, you'll have to do a lot of research and solve a lot of tricky puzzles. But if you do find it, you'll become a famous treasure hunter and may win a prize!
