Firstly, the Lachanas museum was closed when it should have been open, according to the published opening time. Then up to Fort Rupel, but when I arrived at around 1:30 I was told it would reopen at 8pm. Yesterday I turned up at The Balkan Wars museum to be told it was closed because of a presentation ceremony. In contrast, sites and museums operated by the culture ministry have all been open and at sensible times. Frankly, if the army can't staff it's museums, it should hand them over to a department that can.
The one exception was the excellent War Museum in Thessaloniki. It could be better signposted, but once found it is a gem, and it was open!
The exhibits are well organised in chronological order, with many panels in English. I found the uniform displays particularly useful, colours are always a challenge for the wargamer. There is a huge array of weaponry, some display cases are crammed full. Finally, a few interesting weapons on display outside the building.
