Flags With Shields: 18 Flags Featuring a Coat of Arms

At least 18 national flags feature a shield or a full coat of arms, including Spain, Portugal, Ecuador, Bolivia, Peru, Guatemala, El Salvador, Nicaragua, Costa Rica, Fiji, Eswatini, Kenya, Montenegro, Serbia, Slovakia, Slovenia, Moldova and Egypt.

Why So Many Flags Carry a Shield

The shield is one of the oldest symbols in flag design. It comes directly from European heraldry, where a coat of arms identified a knight, a family or a kingdom. When nations began adopting flags in the 18th and 19th centuries, many placed their national arms at the centre so the flag could carry a compact story of history, geography and values.

Central and South American republics inherited this habit from Spain, then filled their shields with volcanoes, oceans and liberty caps. European states used shields to display centuries-old dynastic heraldry, while African and Pacific nations adopted the tradition through British colonial rule. The result is a global family of flags that place a detailed emblem at their heart.

European Flags With Shields

• Spain: Red-yellow-red horizontal bands with a coat of arms toward the hoist. The shield shows the arms of the historic kingdoms of Castile, Leon, Aragon, Navarre and Granada, flanked by the Pillars of Hercules.
• Portugal: Green and red field with an armillary sphere and a shield. The shield's five small blue escutcheons recall a legendary victory over five Moorish kings, and the sphere symbolises the Age of Discovery.
• Montenegro: Red field bordered in gold with a golden double-headed eagle and a central shield bearing a lion, reflecting the country's royal heritage.
• Serbia: Red-blue-white tricolour with the national coat of arms shifted toward the hoist. The shield carries a white double-headed eagle and a cross with four firesteels.
• Slovakia: White-blue-red tricolour with a shield near the hoist showing a white double cross on three blue hills, representing the mountains of Tatra, Fatra and Matra.
• Slovenia: White-blue-red tricolour with a shield depicting Mount Triglav, wavy lines for the sea and rivers, and three gold stars from the arms of the Counts of Celje.
• Moldova: Blue-yellow-red vertical tricolour with a coat of arms on the yellow band. The shield shows an eagle holding a cross, an olive branch and a sceptre, with an aurochs head on its breast.

Latin American Flags With Shields

• Ecuador: Yellow-blue-red bands with an elaborate coat of arms featuring Mount Chimborazo, a steamship, and a condor spreading its wings above the shield.
• Bolivia: Red-yellow-green tricolour with a coat of arms on the central band, showing Cerro Rico of Potosi, an alpaca and a wheat sheaf, ringed by flags and a condor.
• Peru: Red-white-red vertical bands with a shield on the white centre displaying a vicuna, a cinchona tree and a cornucopia of gold coins, representing the nation's animals, plants and minerals.
• Guatemala: Sky blue and white vertical bands with a coat of arms showing a resplendent quetzal, a scroll, crossed rifles and swords, framed by a laurel wreath.
• El Salvador: Blue-white-blue bands with a coat of arms containing a triangle, five volcanoes, a liberty cap and a rainbow, encircled by the words for the Central American federation.
• Nicaragua: Blue-white-blue bands with a triangular coat of arms holding five volcanoes, a liberty cap and a rainbow, closely echoing the old Central American union emblem.
• Costa Rica: Blue, white and red bands with a coat of arms toward the hoist featuring three volcanoes, two oceans and merchant ships, topped by seven stars for the provinces.

African and Pacific Flags With Shields

• Kenya: Black, red and green bands with white fimbriations and a central Maasai shield crossed by two white spears, symbolising the defence of freedom.
• Eswatini: Blue, yellow and red bands with a large black-and-white Nguni shield laid horizontally, along with two spears and a fighting staff decorated with tassels.
• Fiji: Light blue field with the Union Jack in the canton and a shield from the national coat of arms showing a British lion, sugar cane, a coconut palm, bananas and a dove of peace.
• Egypt: Red-white-black tricolour with the golden Eagle of Saladin centred on the white band. Although often called an eagle, it functions as the national emblem and holds a scroll bearing the country's name.

What the Shields Represent

Most flag shields fall into a few themes. Latin American emblems repeatedly show volcanoes, two oceans and liberty caps, a shared legacy of the short-lived Federal Republic of Central America. European shields lean on medieval heraldry, especially the double-headed eagle used by Serbia and Montenegro and the double cross of Slovakia. African and Pacific shields, such as those of Kenya and Eswatini, use traditional weapons and warrior shields to express independence and cultural pride. In every case, the shield lets a flag pack a dense visual narrative into a single emblem.

Frequently Asked Questions

Which country has the most detailed shield on its flag?

Ecuador and Bolivia are strong contenders, since their coats of arms include mountains, animals, ships and condors rendered in fine detail. Portugal's flag is also highly intricate, combining an armillary sphere with a layered shield of castles and escutcheons.

Is a coat of arms the same as a shield on a flag?

A shield is the central element of a coat of arms, but a full coat of arms usually adds supporters, a crest, mottoes or wreaths around the shield. Kenya's flag shows a shield alone, while Ecuador's shows an entire coat of arms.

Why do so many Central American flags look alike?

Guatemala, El Salvador, Nicaragua, Costa Rica and Honduras all descend from the Federal Republic of Central America, which used blue-white-blue bands and a triangular emblem of volcanoes and liberty caps. After the federation dissolved, each country kept a version of that design.
