The flag of Sweden (it’s called Sveriges flagga in Swedish) is a light blue field with an offset yellow or gold Scandinavian cross asymmetrically placed closer to the hoist. The Nordic cross design traditionally represents Christianity. The design and colours of the Swedish flag are believed to have been inspired by the coat of arms of the country dated back to 1442, quite similar to the Danish flag. Blue and yellow (or gold) have been used as Swedish colours at least since Magnus III’s royal coat of arms of 1275.
The Swedish flag was adopted on 22 June, 1906
