Rjukan - Notodden industrial heritage was added to the UNESCO World Heritage List in the summer of 2015. Founder Sam Eyde's vision of "setting the waterfall to do useful work for people", was the start of what was to become Hydro and an industrial adventure Norway has never seen before.
Notodden was the starting point for the world's first successful industrial production of fertilizer. Initially, the Tinfos I power plant provided the energy needed to produce artificial fertilizer using the arc furnace and the Birkeland-Eyde method.
