We had a rather lovely trip to Nuremberg.
Good to hear, that you had a nice time in Nuremberg.
I share your opinion on the Court Room nomination, but I like the idea that it is on the T-list. The final decision is expected for next year. And I can understand that the authorities in Nuremberg have nominated the courtroom for the new T-list and not the Nazi Party Rally Grounds (which was also suggested a few years ago). Of course, they prefer to be associated with a positive site and they don't want to create an iconic site for Neo-Nazis. In this respect, they dealt indeed very well with the area: preserve the remains, install a documentation centre, and open the grounds for the public as an urban recreational area.
Re: "Reinheitsgebot for intangible heritage"
My support too. Germany recently ratified the Unesco Convention on Intangible Heritage and is now collecting proposals for the first nominations. Thus, in these days Google search yields a bulk of suggestions of strange traditions, rural customs and local folk festivals, widely unknown to everyone outside the respective town. The Reinheitsgebot is certainly one of the most conclusive suggestions.
But what does this tell us about Germany? Intangible heritage are the "French Cuisine", the Vienna "Kaffehäuser" ... and German beer, :-)
