It is divided into two parts and its length must always be twice the width:

     The upper one, in red: representing the blood spilled by martyrs and heroes, in the different historical periods and the cause that we defend.
     The lower one, green in color: represents our forests and surroundings, where the historical evolution of this town developed.
     Cuban Crocodile: it symbolizes the fauna, prehispanity and the territory of the province of Ciudad Real.
     Laurel branches: synonymous with victories.
     Blue border: Symbolizes the natural element that identifies the great wetland (water).

Observed and analyzed as a whole, it shows that the Ciénaga de Zapata is the land of VICTORIAS.
