New Orleans, LA. Adopted in 1918. The City of New Orleans flag consists of three gold fleur-de-lis arranged in a triangular pattern, two centered higher, one centered lower, on white field framed by a red horizontal band along the top edge and a blue horizontal band along the bottom edge. The red, white and blue colors match the colors of the flags of both the United States and France. The gold fleur-de-lis are borrowed from traditional French fleur-de-lis flags. The City of New Orleans flag was adopted by the Commission Council February 5, 1918 in honor of the City's Bi-Centennial.
