The world's flags include dragons, birds, weapons, stars, celestial objects and even a non-rectangular shape. What makes a flag unusual is often the story behind the design.
1. Nepal — the only non-rectangular national flag
Nepal's flag is made from two joined triangular pennons rather than a rectangle. It carries a moon and sun and has a dark-blue border around its crimson field. Nepal's Constitution specifies the design and its construction. citeturn1search24
It is probably the easiest flag in the world to recognise from its outline alone.
2. Switzerland — a square flag
Switzerland's normal national flag is square, with a white cross on red. The Swiss Confederation describes it as the only national flag in the world that is square. A rectangular version is used at sea. citeturn0search7turn0search59
3. Bhutan — a dragon
Bhutan's flag features a white dragon holding jewels. The dragon is associated with the country's name, Druk Yul, commonly translated as “Land of the Thunder Dragon”.
It is an excellent example of a flag using a creature that is central to national identity rather than a simple geometric symbol.
4. Mozambique — an AK-47
Mozambique's flag is famous because its emblem includes an AK-47 rifle alongside a hoe and an open book. The objects represent different aspects of the country's history and society.
It is one of the most distinctive political symbols found on a modern national flag.
5. Brazil — a starry sky
Brazil's flag contains a blue globe with stars representing the sky, together with the national motto Ordem e Progresso. The arrangement is based on the appearance of the sky over Rio de Janeiro.
Rather than using a small number of decorative stars, Brazil turns the night sky into a major part of the design.
6. Belize — a detailed coat of arms
Belize's flag is unusually detailed. Its central coat of arms contains tools, a mahogany tree, a shield and other elements connected with the country's history and economy.
It is much more intricate than the simple geometric flags that dominate many national flag collections.
7. Turkmenistan — an intricate carpet pattern
Turkmenistan's flag has a vertical ornamental band containing five traditional carpet motifs. It also includes a crescent and five stars.
The result is one of the most detailed national flags in the world.
8. Sri Lanka — the lion flag
Sri Lanka's flag contains a golden lion holding a sword. The lion is a major symbol of Sinhala identity and gives the flag a strong heraldic character.
Why are unusual flags interesting?
Unusual flags often make the best starting point for learning. Their distinctive features give you a question to investigate: Why is Nepal shaped like that? Why does Bhutan have a dragon? Why does Switzerland use a square?
And once you know the answer, you often know something about the country's history as well.
