The Andorra flag was officially adopted in 1866.
The flag features three equal vertical bands of blue, yellow, and red with the national coat of arms centered in the yellow band. Those colors are said to represent Andorra's independence from both France and Spain, as blue and red were taken from France, while red and yellow were taken from Spain.
Andorra's coat of arms was adopted in 1969, and contains a shield divided into four sections with the national motto, Virtus Unita Fortior ("United Virtue is Stronger"), displayed below.
