I took the opportunity of a free day, and great weather, to visit the War Museum of Athens. I have visited it in the past, but wanted to see how a long-lasting renovation process had changed it. In simple terms, this has become quite a cool museum and is well worth your time. There is now even a model shop in the museum, and I bought a nice book on the Balkan Wars "Memorabilia of the Balkan Wars: by Vasilios Nikoltsios and Yannis Mylonas. This contains all the illustrations from the Mylonas book on Balkan War uniforms, and tons of other artifacts. It covers all the armies of the wars. A must have and it seems to be only available at the War Museum (in Greek and in English).
The museum covers antiquity to 1974, with special focus on the Balkan Wars, and World War 2. It does not cover the Civil War. It has fewer artifacts than the National Historical Museum, but more pictures and art.
For those of you who might not get a chance to see it, or who would like to check out pictures, here is a massive amount of pictures. I will not put captions beyond some points.
