Odda Smelteverk

The Odda Smelteverk is a smelting facility spanning 56 hectares at the end of Sorfjorden, with mountains of the Hardangervidda plateau forming a natural backdrop. The complex includes laboratories, workshops, forges, storage facilities, and a cable car system connecting to import and export docks.

The facility was founded in 1906 by British companies and began operations in 1908. It grew to become the world's largest cyanamide production facility by 1912.

The site represents how Norway rapidly developed industry in the early 1900s by harnessing hydroelectric power from the surrounding landscape. Walking through the complex, visitors see how this industrial growth shaped the region.

The site is large and spread across multiple areas, so plan time to explore thoroughly. Wear sturdy shoes, as you will be walking considerable distances and the terrain can be uneven.

Scientists here developed the Odda process for nitrophosphate production in 1927, which gained recognition in fertilizer manufacturing worldwide. This technical breakthrough influenced agricultural practices internationally.
