Thieves have broken into the Chinese Museum of the Palace of Fontainebleau in Paris and made off with 15 artifacts from China and Thailand. Some of the items, in fact, were originally taken from the Old Summer Palace when it was burnt down in 1860.

The stolen items include a 19th century replica of a Siamese Crown, and a cloisonne kylin (a Chinese unicorn) from the Qianlong period of the Qing Dynasty’s sixth emperor. All of the stolen items were given by Napolean III to his wife Josephine as gifts in 1863, and are considered priceless.

The thieves broke into the facility at 6am and were finished pilfering the artifacts within seven minutes, astonishing the museum management. The director of Fontainebleau told AFP he was deeply shocked by the burglary. “The thieves were very decisive and assured, and they were clear about which items they wanted. The way the crime was committed was very professional.“
