Château de Blois
Claude died on 20 July 1524 at the Château de Blois, aged twenty-four. The exact cause of her death was disputed among sources and historians: while some alleged that she died in childbirth or after a miscarriage, others believed that she died for exhaustion after her many pregnancies or after suffering from bone tuberculosis (like her mother) and finally some believed that she died from syphilis caught from her husband. She was buried at St. Denis Basilica.
