Very interesting history on this, what used to be the worlds largest hydro power plant. First heavy water of industrial scale was produced here during ww2. The factory was sabotaged multiple times to block the Germans from producing an atom bomb which uses heavy water as a moderator. Vemork - well worth a visit!

Amazing museum. I was there just after the new exhibit opened and 10/10 would recommend. It gives a full history of the facility and the harrowing Norwegian effort to destroy the heavy water production during WW2.

The museum itself and the exhibited machines are quite good. But there is a big ‘but’: the organisation and information from the staff is pretty bad and leaves a lot room for improvement. Why? A) You barely find information that you need to take a bus from a parking lot 5km away. B) You barely get information from the staff when and where the busses return. C) We asked the bus driver when the (smaller shuttle bus) bus will go back and he answered 16:25. By appearing a 16:20 we just saw the small shuttle already winding down the narrow road on his way to the main bus. We then needed to run the small road down to catch the 16:30 bus at time. Next bus would have been one hour later. Please improve the communication to your customers and train your staff to give proper answers to valid questions.

Very interesting, quite a lot to see only had 2hours but could have spent much longer

Just being outside the building with the spectacular location is in itself a very unique experience. The power plant is very well preserved, and you have access to the main production hall. But the different exhibitions are rather small, and more could have been done to tell the wartime and industrial history. From the parking lot there is a 700 meter walk in steep ascent in spectacular nature, including a suspension bridge. At the ticket office you pay for entrance which gives you access to three different exhibitions. The main purpose of the museum is to tell the story of how life in Rjukan was during the industrial development in early 1900s, and the fight for workers' rights. It would be reasonable to assume that a majority of the visitors come to learn and experience what the place is known for: the wartime history and the heavy water sabotage. Those visitors might feel that more space and a more extensive exhibition could have been dedicated to tell the story of the resistance, and how life was during the war.

The heavy water part of the museum is excellent and very well described and the story is well told. However the descriptions and storytelling about the machine room in the power plant part is terrible. The logistics in the summertime is chaotic at best. Bus shuttle from downtown Rjukan to the museum itself and back. Bring your own water and food. The prices are out of this world even by Norwegian standards.

This historic setting is not to be missed. Watch the film about the sabotage on YouTube beforehand.

Interesting to see the museum, the history about how it was build and what conditions the workers had, nature and surroundings are spectacular, but i wish there was more information about the history during wwii

A magical place! Unfortunately I can only make it shortly before closing or when it is already closed. But even seen from the outside, it's extremely impressive in size & difficult to photograph due to its length. The best perspective is from the valley road further up. There you can also see the more than 4 kilometers long steel pipes that supplied the power plant with water at the time. There are 3 things new: 1. now you should no longer park in the parking lot right next to the museum because the access road is very narrow. That's why you should now buy the tickets online and take the yellow shuttle bus that has been specially created for this purpose. It starts in the city below. Admission per person is now 200 NOK 2. The ruins of the bombed-out former building have now been integrated into part of the museum and completely redesigned. 3. There are now 2 shady dog ​​parking spaces to the left of the entrance (lockable boxes, see pictures). But we haven't tested it. Depending on the dog, this may be a good idea if the dog is used to crates. My tip: go all the way to the back on the right. There you can still see the previous tests behind the wire fence and the huge supply of water before it was diverted into pipes. The proud waterfall, which unfortunately disappeared with the reservoir, can only be admired in pictures.

+Very interesting museum, learned a lot about Norwegian industry history and the famous sabotage during ww2. Nice guide. -No guide tour in the famous cellar.

Interesting museum with interactive screen for the basement where the allied forces came in to bomb the heavy water production. It was good with information in English apart from the section celebrating the fire service which is Norwegian only. I do feel that it was a little overpriced for the entry for what you got inside.

The museum was fascinating! Knowing the Heroes of Telemark film, it was great to see the location of this incredible feat. The team of Norwegian soldiers were so incredibly brave. The museum is high up with only a gorge bridge crossing, fairly scary to walk across but a bus runs from the car park if required. A nice cafe and shop are in the museum.

What to expect here: At the museum you will get a close encounter with Norwegian industrial - and war history. Highlights: Kids friendly (including kids play room) Heroes of Telemark/The heavy water war The industrial town of Rjukan The movie: "If Hitler had the bomb"

Impressive facility in an impressive region! It was really exciting to watch 👍🏼👍🏼

A really interesting place. The history about the contrubution of the Norwegian resistance in the race for the atomic century is presented in a very fascinating way.

Great historical places with clean and friendly staff. The place is well kept

So if you are like me who likes to read and visit places of historical value that you must visit here . I just don't know why it's not made more open to tourists as it was extremely quiet with visitors on my visit . If things had of ended differently our world would today be different this place is a must and especially if you have interest in WW2. There is a shuttle bus but the walk up the mountain well it gives you a sense of it more .The rail tracks which lead to the river etc.. Without history how would we understand our world. 😊

A very interesting and atmospheric place

I visited as part of a military trip here. It was good to learn the history around the heavy water operation. Very good that you can see some remains onside. Thank you for the very detailed account from the tour guide. Slightly disappointed with the Cafe, it was closed possibly due to the time of year. I think they had a private group booking, I believe they will cater for groups anytime of year.

You just wonder how big of an influence this small place made in the 1940s. But apart from that there is Norwegian working culture that developed here due to this factory that the current working force enjoys. That museum has done a great job protecting and showcasing the history.

A fascinating visit highlighting one of the premier Norwegian military actions of the Second World War. The museum is very well done and has some excellent displays and explanations (in multi languages). Good cafe for lunch or snack. The only challenge in the off season is a 700 meter steep climb using a paved road to get from parking to the museum. Wear good walking shows but well worth the walk, most especially if you are a student of military history.

A piece of WW 2 history you don't want to miss

Nice place to visit. Inportent part og history there.

Flagship is the re-built heavy water cellar and related saboteur exhibition. The rest of the museum is fascinating, but completely lacks the explanatory guidance and labelling that is found in the cellar.

To be absolutely honest, after all the hype I've heard about this place, I was a bit dissapointed. The exibitions are word, poorly contruction and lacks with information. The mainproduction hall with the turbines have no information whatsoever about the turbines, how they function or anything. I get that this is not a technical museum, but come on! Its your main display feature and there was not a single information sign. Not one! As for the workers exhibitions it was telling very little other than what we already knew from common knowledge. There were where few items at display and entire rooms full had information in norwegian only. The caffeteria food was ok, although quite expensive. It was interresting to see the newly dug up heavy water explosion are, but again, very little information. The museum need to step up and become what a museum is supposed to do - educate. I wouldnt go as far as saying that it was not worth the entrance fee or visit, but I will not be comming back.

Nice scenario outside, including the walk across the bridge and up too the museum. The museum itself is mostly for those that are technological interested, with a background in electrical, process and mechanical. The exhibition about the early beginning of the Union work and the fight for workers rights, is quite interesting and good

Came here having known a little of the WW2 story, but the museum covers so much more of the local history of the valley. The site is so much more than the few years during it's occupation, and it's good to see the wider story of the area as well as the courage and drama of WW2 in the context of the location it happened in. We were fascinated by the development that took place to install and utilise the hydro resource! A couple of the exhibits needed a bit of repair, which is sad as they'd have helped with the storytelling and demonstration of the technical aspects of the site to our children, but also as a note we came here after the Norwegian schools had gone back, so the museum had an 'out of summer holidays' feel about it. It may have been that they were going into a maintenance period after the summer rush. Disabled access was good, considering the original industrial nature of the site, the wheelchair user in our group didn't have an issue getting around.
