Marie Antoinette was originally buried in an unmarked grave
Marie Antoinette was hauled before a tribunal in September 1793, nine months after her husband was executed for high treason, and was accused of a number of crimes, including providing money to their Austrian adversary. Most concerningly, she was also charged with sexually abusing Louis Charles, her only surviving son. The queen was judged guilty of her "crimes" on October 14, despite the fact that there was no solid evidence to support the latter accusation.
Marie Antoinette, 37, was publicly executed two days later while wearing a simple white dress and short hair. The Madeleine Cemetery in the city then received her body and disposed of it there. It was a tragic end for a woman who had lived an extravagant life; the queen's remains would later be found and put in a tomb with her husband.
