Faint rays from the winter sun reached the market square for the first time yesterday thanks to three 17-square-meter mirrors placed on a mountain.
Cheering families, some on sun loungers, drinking cocktails and waving Norwegian flags, donned shades as the sun crept from behind a cloud to hit the mirrors and reflect down onto the faces of delighted children below.
The plan to illuminate Rjukan was cooked up 100 years ago by the Norwegian industrialist Sam Eyde, who built the town to provide a hydroelectric plant to workers.
