Sunlight by reflectionSourced
A shaded town sent sunshine down with mirrors
Mountains block direct sunlight from Rjukan, Norway, during the darker part of the year. A project installed large hillside mirrors in 2013 to reflect sunlight into town. The illuminated area is part of the square, not the whole town.
The solution changed the light’s direction, not the mountain.
