I spent 2-3 hours in this museum and saw everything. It had a temporary World War I exhibit (I actually went in 2014, not 2017) that was exceptionally well done with full-scale mock-ups of trenches, etc. When you see everything and consider the breadth, depth and rarity, it's a superb museum, not just a superb military museum. The collection is not as big as the military museum in Brussels, but it's far better preserved and presented. It's certainly better than the military museum in Istanbul, which also is quite good.
