Flag of Portugal. The five blue shields comprising the cross in the center represent the five Moor kings defeated by the first King of Portugal, D. Afonso Henriques. The dots inside each blue shield represent the five wounds of Christ when crucified. Counting the dots (and doubling those 5 in the center) there are 30 dots that represent the number of coins Judas received for having betrayed Christ. The seven castles in the shield's outer ring represent the number of fortified cities Henriques conquered from the Moors; the golden globe represents the world discovered by the Portuguese navigators in the 15th and 16th centuries; the green field is meant to symbolize hope in the future, and the red field represents the blood of the Portugal's heroes.
