It's a wonderful museum, I was lucky to get free admission, and the tour in Russian cost 2000 drams. I learned a lot of new and informative things, which our textbooks do not focus on (and in vain, in my opinion!). It was incredibly interesting, I highly recommend it to visit - it was so exciting that there was absolutely no time to take photos of the museum. They say it will be even more interesting on city Day, I'm looking forward to it!
