I have not been to other concentration camps, there is nothing to compare it with, and since this was the first experience, it was quite impressive.
It's not an easy sight (there is a lot of information in the museum, in Serbian and English, so you should set the time: at least 2 hours if you want to learn at least something).
The atmosphere is oppressive and terrifying in places, especially if it happens that you are practically alone in the rooms (this was the case with us).
It was not an easy experience, it was interesting, of course it was quite difficult, but you need to know such things.
A ticket for an adult cost 600 dinars. We were there on Sunday afternoon. People came and went, there was no crowd.
I'm still impressed, even though we were there a week ago. It felt like I had plunged into the history of mankind.. We felt the pain and despair of the people who were there...a wall of execution, solitary confinement cells...
