Flag from Wikipedia
The three fleur-de-lis on the blue field represent the French heritage. The fleur-de-lis is a symbol of the kings of France.
The gold star on the white background represents the Virgin Mary, (Our Lady of Assumption), Patroness of the Acadians. This represented their Catholic faith.
Another interpretation is that the star is a reminder of the efforts of the Acadian volunteers in removing British from areas adjacent to the Spanish Louisiana boarder (Baton Rouge, Mobile, Pensacola) under Louisiana Governor Galvez.
The gold castle (or tower) on the red field represents the Spanish kingdom, who allowed and even assisted the Acadians in settling their new homeland.
