Assif mentioned under a different topic (WHC 2018) three German sites with WH potential: AEG-Turbinenfabrik, Olympia-Stadium, Tempelhof
https://www.worldheritagesite.org/forums/index.php?action=vthread&forum=16&topic=1836 &page=18#msg18761These sites would be worthy additions to the list, also in my opinion.
In all of these cases commercial interests seem to be the major issue that affect a potential nomination.
AEG-Turbinenhalle: owned by the Siemens AG and still used for the original purpose, the production of turbines. But in contrast to the Fagus factory, where the private owner was a driving force in the WH process, the Siemens Group obviously has no interest.
Olympiapark Munich: owned by the Olympiapark München GmbH, which is owned by the city of Munich; today the Olympiapark is only rarely used for sport events, but for concerts, festivals, fairs, even for a car race. However, recently a private initiative was lauched to promote a WH nomination.
Tempelhof: owned by the city of Berlin; the building is protected as a historical monument, the airfield is a huge undeveloped area close to the centre of the city. Currently there are no activities towards a WH nomination. Next week I will visit Berlin and I already booked a guided tour to the Tempelhof building, so I can verify whether it would be a worthy WHS.
