After the treaty of Verdun in 843 that give a part of the Flanders to Charles le Chauve, he entrusts a warrior named Baudoin-Bras-de-Fer with the area to improve the defence against the Norman. Baudoin-Bras-de-Fer has found the first house of the count of the Flanders in 843 and the arms with the lion appear in this area. Lion is the most representative animal in heraldic art because it represents strength and majesty. The actual lion of Flanders, sable above a golden background would be the one of Jeanne of Flanders's escutcheon. Jeanne of Flanders was a good countess and has governed Lille from 1213 to 1244 when her husband was taken prisoner during the battle of Bouvines. This escutcheon looks better.

Louis XIV wage war against the Spanish to lay claim to the dowry of his wife Marie-Therese. He come in Lille during the month of August 1667 through the ill gates, now called gates of Paris. A triumphal arch is elevated to his glory. Lille becomes a French town in the treaty of Aix-la-Chapelle in 1668.

The armorial bearings represent the lis flower that is the symbol of the mother of God and is became the emblem of the royalty in the reign of Louis VII (1120-1180). It is argent above a background of gules. It is taken from the house of Bourbon that belonged Louis XIV. We could find it on the arms of the town Bourbon-l'Archambault (in the department of Alliers) that gave the name to the seigniory Bourbon and on the blazon of Bourbonnais and Artois.
