I think Its the best museum in Kaunas who like war history, a lot information about 1890-1945 very interesting
The ninth fortress is to commemorate the civilians who were imprisoned and killed by the Nazis during World War II. It was once a Nazi death camp. It is 7 kilometers away from the city of Kaunas and can be reached by car or bus.
The Ninth Fortress is a symbolic attraction of Kaunas County. It is on the northwest corner of the old city. You can see it from the Resurrection Cathedral northbound and then westward. It is an important fortress built by the Nazis during World War II. It is also a large concentration camp. I feel that standing here seems to be able to feel the cruelty of the war at that time, and I feel that peace is hard-won.
The fortress against the blue sky is extraordinarily magnificent, with strong color contrast. The entire castle is quite large. It takes more than half an hour to go around. There is also an exhibition hall inside.
On the far northwest corner of the old city, you can see the Resurrection Cathedral from the north and then west. In my opinion, it is the most worth seeing place in Kaunas. The place is hard to find, but it feels mediocre!
