This leaves me perplex, especially because it originates from a political boutade by the populist wing in the debate about the new San Siro stadium (or better speculative district), but oh well, who knows what will come out of it!!!

On the pre-2021 list, for Italy we are probably missing the Tiber, which was enthusiastically proposed some 1,5 years ago and which tricked me since they were apparently far in the process, but from then on I cannot find any news.

Another article (in German) about the why the Bergedorf Observatory should be World Heritage:

Warum die Sternwarte in Bergedorf UNESCO-Welterbe werden soll

Because nowhere else, argue supporters of this idea, is the transition period from classical astronomy to modern astrophysics more visible than here.

Fraktos Forest in Paranesti, which is part of the Rodopi Mountain Range National Park is potentially seeking to be added to the Greek Tentative List. My interpretation is that this would be an extension to the Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe (though I could be mistaken).

This region of Northern Greece is clearly identified here as part of the "Beech Forest" Area of Europe.

Latest report, City of Phrae changed their goal to UNESCO Creative City Network - Craft and Folk Art instead.

Maybe a transfrontier extension of Pirin

I can't recall if this already popped up, and I couldn't find the key-name in the forum, but:

Italy - Forte di Fenestrelle (& Forte di Exilles)

- article of 25/1/22

20 million euros to salvage and develop the site, also in the perspective of opening a panel for its candidature. This fort is truly huge.
