This is another museum about third reich in Berlin. The museum has 2 exhibitions: Hitler and the third reich - how could it happened? this is the main one. and the other exhibition is the Berlin story, I went to the main one only. the price is 12 Euros, and if you take the mp3 audio-guide it is another 1.5 Euros, but it is not a must! Just follow the number of room from 1 to 36. Each room has a lot of information and a lot to read. The museum is in an actual bunker that was first used nazis to hide from air bombs, near a place named Anhalter Station. Later it was opened to the general population. The tour takes about 2-5 hours, depends on yor pace. Because you are all the time inside an actual bunker it could be somewhat clastrophobic sometimes. Almost every room there is a chair you can sit and read what you need. For me I haven't learned many new things because I know well the history and also it is not a very authenthic museum. Most of the exhibits are replicas and most of them are not original, and the subject - "Hitler - how did it happen" is VERY pretentious. After visiting all the room 1 to 36, you enter a small cafeteria and book-store and WC. In the cafeteria there is coffee and some snacks, you take what you like and each item is 1-Euro, you pay when you leave, there are no waitres. No photos can be taken inside they are very strict about it!
