Facts about the industrial heritage
The actual World Heritage Site area is defined from Møsvannsdammen to the waterfront at Notodden - a continuous 92 kilometre area made up of four central components:
• Power production with dams, tunnels and power stations
• The factory areas with the differing production methods for artificial fertilizer.
• The towns of Rjukan and Notodden as ”company towns”
• The Rjukan railway transport artery - Tinnos railway with train, two ferries, two harbours and one slipway, as well as selected station areas.
As part of the World Heritage Site application, the Directorate for Cultural Heritage gave protected status to the boats on the Tinnsjø, D/F "Ammonia" and M/F"Storegut", the Tinnos railway and the Rjukan railway. The factory areas in Rjukan and Notodden, Vemork power station and Hydro's representation building Admini at Notodden have been given protected status.
A buffer zone has been defined around the World Heritage site. The mountainsides from Rjukan to Notodden are included, as well as the open water of Møsvatn in the municipality of Vinje.
