This is a tricky review to write. It was an utterly harrowing experience, really showcasing the horrors of the 20th century and what people are capable of doing to each other.
You can go into the main hall for free, however you can't go into the cells etc without a guided tour, but for the 15 euros it's really good value for money.
I'm glad I did the tour and it's an important reminder that Freedom is never guaranteed. The tour guide was excellent, highly knowledgeable and struck the right balance of tone when presenting information.
It's not an experience I would want to be doing everyday, but it's important to learn about this stuff.
