At the junction of the green and red sections lies the national coat of arms of Portugal, consisting of an armillary sphere (a historical astronomical instrument) overlaid with the traditional Portuguese shield.
Green: Originally represented hope (associated with Prince Henry the Navigator).
Today, it is also viewed as a symbol of the Portuguese nation's hope.
Red: Represents the blood, courage, and triumph of Portuguese explorers and the people.
The Armillary Sphere: Refers to the global discoveries made by Portuguese navigators during the 15th and 16th centuries.
The Shield: The small shield in the center displays five small blue shields (*quinas*), each bearing five white dots (symbolizing the wounds of Christ or the five Moorish kings), surrounded by seven golden castles representing victories over the Moors.
The current flag was officially adopted on June 30, 1911, shortly after the fall of the monarchy and the establishment of the Portuguese Republic in 1910.
Prior to this, the country used flags in different colors (predominantly blue and white).
