Blanche of Castile (Spanish: Blanca de Castilla; 4 March 1188 – 27 November 1252) was queen of France by marriage to Louis VIII in 1200. She was regent twice during the reign of her son, Louis IX: during her minority at from 1226. until 1234, and during his absence from 1248 to 1252. This motif of fleur-de-lis and castles of Castile is of a familiar design in Paris and throughout northern France, including Normandy , where a kiln producing a similar design was identified by archaeologists. The castle bears the insignia of Blanche of Castile, mother of Saint Louis (1214-1270). While the fleur-de-lys is the emblem of the king. Variations were adopted in England where the type is associated with Eleanor of Castile (c. 1290-1310), first wife of Edward I of England.
