If you're in Nuremberg, it is worth the trip. It's very informative and tells about Hitler's rise to power. You can rent an audio tour but it isn't in the form of headphones so it's more like holding a phone receiver to your ear the whole time and allows for many distractions from other tourists. The other thing is that if your native tongue is English and you don't read German, you will not be able to read the different posters on all the different events as they are all in German. I did enjoy the interviews of local Nuremberg folks via film clips who lived in Nuremberg during hitler's reign. These were first hand accounts I had not heard before.
