Question: what does the symbol mean on the mexican flag?
Answer: Flag of Mexico. ... The central emblem is the Mexican coat of arms, based on the Aztec symbol for Tenochtitlan (now Mexico City), the center of the Aztec empire. It recalls the legend of an eagle sitting on a cactus while devouring a serpent that signaled to the Aztecs where to found their city, Tenochtitlan.
