Situated in the Vemork hydroelectric plant, on the very grounds of the Heavy Water Sabotage during World War II, Vemork has several exhibitions about the local history of the industrial worker as well as war exhibitions.
Norwegian Industrial Workers Museum is an industrial museum located at Rjukan in Tinn Municipality, Norway. Located in the Vemork power station, it was established in 1988 to allow the preservation of industrial society created by Norsk Hydro when they established themselves in Rjukan in 1907. The museum is an anchor point on the European Route of Industrial Heritage.

Gaustatoppen
Highest summit south of Hardangervidda and highest in Telemark, a distinct profile. About 1/6th of Norway can be seen on clear days. 30,000-40,000 people hike to the summit every year, taking approximately 2-3 hours from Stavsro, where you can park the car. You can also take the Gaustabanen Cable Car inside the mountain.
Rjukanbanen
The 16-km-long railway was operational between 1927 and 1991. In Mæl cargo (consisting mainly of chemicals produced in Hydro's fertilizer plant) was loaded onto ferries for transport across the lake to Tinnoset. In 1944 a steam ferry Hydro was sunk on the way from Mæl (as a part of Norwegian heavy water sabotage) with a cargo of heavy water for Nazi nuclear weapon project.
