🇵🇹 The flag of Portugal consists of two vertical bands, with the green band on the hoist side and the red band on the fly side. In the center of the green band is the Portuguese coat of arms, which features a shield with seven castles representing the historic victories of Portugal, and five smaller blue shields with silver bezants, symbolizing the five Moorish kings defeated by King Afonso I. Above the shield is a white curved armillary sphere, which represents Portugal's maritime history and exploration. The flag has been used since the 12th century and is a symbol of the nation's rich history, culture, and seafaring heritage.
