Fleur de lis

All flowers have a meaning., the Victorians used to use flowers as a symbol to express their feelings

It is particularly associated with the French Monarchy in a historical context, and continues to appear in the arms of the King of Spain and the Grand Duke of Luxembourg, members of the House of Bourbon.

The symbol is also often used on a compass rose to mark the north direction, a tradition started by Flavio Gioja, a Neapolitan mariner of the fourteenth century.

In building and architecture, the fleur-de-lis is often placed on top of iron fence posts, as a pointed defence against intruders.

The fleur-de-lis is the main element in the logo of most Scouting organizations, representing a major theme in Scouting: the outdoors and wilderness.

Lily: Purity of heart, Majesty and Honor
