The flag of Iceland was officially adopted on June 19, 1915.
The cross design is modeled after the Danish flag. The color red is said to symbolize the island's active volcanoes; white the ice and snow that covers most of the country, and blue is symbolic of the surrounding Atlantic Ocean.
Iceland's coat of arms consists of the four protectors of Iceland (the bull, the eagle, the dragon, and the rock giant) holding onto a blue shield similar to the Icelandic flag.
