Symbolism
The white (or silver) cross and red ground refer to the fact that the city of San Juan, capital of Puerto Rico and the site of the Headquarters Puerto Rico National Guard, was one of the first Christian communities established in America (1508). The three wavy blue, white and blue bars symbolize water and in addition to also alluding to San Juan harbor are used to indicate that Puerto Rico is an island. The two castle towers allude to the fortress of El Moro which once protected the harbor and now refers to the constant readiness of the Puerto Rico Army National Guard to defend its homeland and combat the forces of aggression. The entire design of the cross and towers as well as the colors red and yellow allude to the Spanish discovery and settlement of Puerto Rico and its Spanish heritage and culture.
