The flag of Nepal is a concave pentagonal flag of red, white, and blue colour. It is used as both the state and civil flag of Nepal. It is the only non-rectangular national flag in the world and the only one that is taller than it is wide. The flag's unique shape is a combination of two single pennants, and is known as a double-pennon. The red colour of the field represents bravery and Nepal's national flower, the rhododendron, while the blue colour of the border represents peace.

The current flag was adopted on 16 December 1962, along with the formation of a new constitutional government. Shankar Nath Rimal, a civil engineer, standardised the flag on the request of King Mahendra. It borrows from the original, traditional design,[5] used throughout the 19th and 20th centuries, and is a combination of the two individual pennons used by rival branches of the ruling dynasty. Until 1962, the flag's emblems, both the sun and the crescent moon, had human faces, but they were removed to modernise the flag. Wikipedia
