Over a dozen rare pieces of art have been stolen from the Chinese Museum at the Fontainebleau Castle outside Paris.
French authorities say two suspects managed to gain entry into the Museum over the weekend, and while only staying inside for 7-minutes, managed to make off with 15 different pieces.
The stolen artifacts include ancient pieces from China and Siam, which is now modern-day Thailand.
Jean-Francois Hebert is the president of Fontainebleau Castle.
"Those are pieces which are simply priceless. For the simple reason that they are singular, original, gifts made to Napoleon III and Eugenie by the King of Siam in 1861. They are also very precious pieces for China. So we can really say the pieces are priceless."
French authorities haven't said whether or not they have any suspects.
Fontainebleau Castle was the residence of French monarchs from Louis VII through Napoleon III.
It's now a national museum.
