It is formed by three vertical stripes, blue the first one, white the second one and red the third one, like those of the French flag, recalling the Gallic origin of Fernandina de Jagua.
But, on this tricolor background, it has some symbols that differentiate them: In the blue stripe, a white equilateral cross that recalls the Christian religion; in the white, the local coat of arms and on the right appear three red triangles with a white star in the center, didimulated by two white ones that flank them.
