The truly vile thing is that makes it an even more apt monument to Nazism than Germania ever would have been, a ruined city built on a pile of corpses, and even if they can't really go and check directly, it won't be hard to guess how many died for a mad monument to a mad man.
And on the pedestal these words appear:
'My name is Ozymandias, king of kings:
Look on my works, ye Mighty, and despair!'
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.
Ozymandias.
