I don't know any of these locations, so I'm sure these are even more amazing for people familiar only with their current state of being. I particularly appreciated image 15 with the soldiers carrying the Soviet flag underneath the modern German flags.
The pictures of the Heldenplatz (here in Vienna) are particularly sobering, considering that its a very bright and vibrant place these days .. oh, except for the one week a year when the Austrian military put on their big displays there, of course .. that is a bit freaky.
