During WWII Denmark had to keep their windows dark at night as the Nazis didn’t want the British planes to use the lights as navigation.
May 4th, 1945 was the day Denmark was freed and as a symbol all the people tore down their dark curtains and put lit candles in their windows as a symbol of peace and freedom.
This became a tradition that is still being celebrated to this day. Today Denmark is celebrating 70 years of freedom.
