On 9th January 1514, Anne of Brittany, queen consort of King Louis XII of France, died at the Chateau of Blois. She left her husband, who went on to marry Mary Tudor, sister of Henry VIII, later that year, and two daughters: Claude, Queen of France, and Renée, Duchess of Ferrara. She was buried in the Cathedral Basilica of Saint Denis, just outside Paris, and was joined there by Louis after his death on 1st January 1515.
The tomb of Anne of Brittany and Louis XII is stunning and you can see my photos of it, along with other tombs, in the video talk I did on my visit to the cathedral in 2015:
In the video I mention an article by Yann Kergourlay about Saint-Denis and you can read that article and see Yann's photos at www.theanneboleynfiles.com/visit-basilica-saint-denis-guest-post-yannkergourlay/
