World War One is hardly at all remembered in Germany, for what it's worth. Mostly because the Third Reich towers immenselsy above anything else in German history. I doubt many Germans could tell you much about The Great War except the years and that we had a Kaiser. And that there were trenches. There has been an attempted revival on TV in past years (e.g. there was a rather outstanding Verdun documentary a year or two back based on participants' correspondence, mostly), but it's still as distant to most people as the crusades.
It's not much different in Vienna (which is where I live). The memory of Imperial glory and the Habsburgs is vivid here (what with all the buildings etc.), but it is very romanticized, and remembering World War One limits itself to a small, obscure memorial on the "birthday" of the republic in November 1918. But ask anyone about Caporetto, Strafexpedition or that Lviv/Lvov was once an Austrian fortress and you get blank stares.
I had to chuckle, though, that in Graz there's a Conrad von Hötzendorf Straße, though.
