The flag of the Faroe Islands is a Nordic cross flag with a white field and a blue cross. The vertical arm of the cross is shifted towards the hoist side of the flag, and its horizontal arms are shifted towards the fly side of the flag. The flag has no official ratio, but it is commonly seen in a 5:8 or 4:7 ratio.
The white color represents the foam of the sea, while the blue color represents the ocean that surrounds the Faroe Islands. The cross design is a symbol of Christianity, which has been the dominant religion on the islands since the Viking Age. The flag was designed in 1919 by a group of Faroese students studying in Copenhagen and was first flown on June 22, 1919, to celebrate the visit of the Danish King Christian X to the Faroe Islands. The flag has been used as the official flag of the Faroe Islands since 1948, when the islands were granted home rule by Denmark.
