Why not Nuremberg trials, just like in OTL? Nuremberg (Nürnberg as we Germans say it) may be a radiated heap of rubble but wouldn't that actually make an excellent stage for a trial of the "war-mongering plutocrats who threw Europe into ruins"? Have the Germans and their limitles labourers build an oppressive looking 30-story court building with a simple, undecorated concrete facade, and hold the trials there.
Nuremberg also has some historical significance, it was one of the major cities of the medieval Holy Roman Empire and the Nazis may want to reinforce their view that Germany is going to be to the brave new Europe what the Holy Roman Empire was to the medieval and renaissance Europe... biggest state, stretching far and wide, its leader seeing himself as the head of Christendom and highest ranking Christian monarch. The Nazis may want to play on this significance.
Alternatively they can hold the trial in Münster, if they want to make it look more like a first step for lasting peace in Europe (Münster was where the peace was signed that ended the 30 years war)
