Located in a dramatic landscape of mountains, waterfalls and river valleys, the site comprises hydroelectric power plants, transmission lines, factories, transport systems and towns. The complex was established by the Norsk-Hydro Company to manufacture artificial fertilizer from nitrogen in the air. It was built to meet the Western world`s growing demand for agricultural production in the early 20th century. The company towns of Rjukan and Notodden show workers` accommodation and social institutions linked by rail and ferry to ports where the fertilizer was loaded. The Rjukan-Notodden site manifests an exceptional combination of industrial assets and themes associated to the natural landscape. It stands out as an example of a new global industry in the early 20th century.
