[4] Crown of Saint Louis or Sainte Couronne de France.
nationalgallery.org.uk
The three medieval coronation crowns which were preserved at Saint Denis were destroyed during the French Revolution. One of these is shown being worn by the king in the 15th-century painting “The Mass of St. Giles”. Some believe that this may represents the French coronation crown even if it looks like more likely the one of Saint Louis with an added cap.[8]Archived 2009-05-07 at the Wayback Machine
