For an eagle with a snake in its mouth, one claw holds the snake, and the other claw stands on a cactus that grows out of the rock in the lake. The pattern depicts the development history of the Aztecs, the ancestors of Mexicans.

According to legend, if an eagle stands on a cactus with a snake in its mouth, the nation will surely flourish. Under the inspiration of God, the Aztecs found such a place and lived in it through hardships, and then gradually developed into Mexico City. The central pattern is decorated with branches and leaves of oak and laurel, symbolizing strength, peace and loyalty to the country.

National Flag Act:

President Ernesto Cedillo issued a decree in 1999 to promote the use of the national flag throughout the country, and erected a large national flag with a length of 14.3 meters and a width of 25 meters on a 50-meter-high flagpole in major cities, including Mexico City and Tijuana. Later, the state governments also erected big national flags in Ensennada and Chihuahua.

The largest national flag was erected in Monterey in 2005, which is about twice as high as other national flags. The flagpole is 100 meter high, 50 meters long and 28.6 meters wide, weighing 230 kilograms, with an altitude of 775 meters.

Mexican nationals also like to decorate with the national flag or use it as a pattern for clothing design.
