Today - December 6th - Finland is
celebrating 100 years of independence. Many countries around the world have joined to celebrate the centennial anniversary by setting blue-white lights on famous buildings or nature landmarks, e.g. Colosseum in Rome, Holmenkollen skitower in Norway, or the Niagara falls in the US.
For those who don't know or remember; blue and white are the colors of the Finnish flag. There are many stories about why these colors were chosen originally but I believe that mid-19th century Finnish historian and author Zacris Topelius was the first to point out that blue and white are colors of our country; white as the snow in the winter and blue as the lakes in the summer.
