I recommend it very much. When we arrived we realized that the museum is actually still a military installation which was impressive. Also, we got a free tour of the museum and the guide was actually an enlisted soldier. He explained everything very nicely, in good English, he was open to discussions too. I will say it is a must visit, if you are looking to learn a lot of Greek history. They will show you items from each war and explain what they were and who had them, I was really impressed about the piece of the tree on which a Greek soldier was hanged, I couldn't believe that they had a piece of the original tree. In conclusion it is a 10/10 and a must see in Kalamata.
