The exhibition in Notodden tells the story of Norway's most important invention: the arc furnace and the production of mineral fertilizer. The so called "Norgessalpeter" laid the foundation for the establishment of Norsk Hydro in 1905. The invention led to a better food situation throughout the world.
A visit to the World Heritage Centre will give you new and important knowledge about the events that earned Notodden and Rjukan a place on the UNESCO World Heritage List. Notodden became the arena for a modern adventure, an industrial adventure that helped turn Norway into a modern welfare society.
The World Heritage Centre, Notodden, is located under the same roof as the Telemark Gallery and has a joint ticket.
