The white color of the cross symbolizes purity and peace, while the red background stands for courage and perseverance.
The HEX codes for the colors are #C60C30 for red and #FFFFFF for white. This flag is based on a legend believed to have fallen from the sky in 1219 in Estonia during the Battle of Lindanise.
Thought to have been a lucky charm for the Danish king Valdemar II, it is still a symbol of national pride today.
Dannebrog has been flying since the Crusades and is also the second longest flying flag in the world.
