1. There is an artist who drew a picture once of Vienna after an attack with nuclear weapons. Only these towers are seen there. They are really very massiv and it is impossible to remove them so now they put them under protection and cultural heritage.
2. A little more facts about the towers. They decided to remove this one by cutting it and pushing it over. But, seismologists then found out that if it falls over there will be a small earthquake that would break all windows and make some damage till the center of Vienna. Unbelieveable isnt it! Millions of tons of concrete!
3. Next fact about this collosus is that the concrete is very strong. In our time now it is not possible to recreate or produce such concrete. Aparently if "Der Führer" said it sould be done, it was done. Fascinating, this will resist any war till the end of days :)
4. Yes, it is strange that is not possible to produce such concrete. When I was taking the fotos in the "Augarten" an elderly man started telling me the whole history of the park and these towers two of which are in this park. This one on the top, is that main one and is connected underground to the neighboring one to give information about incoming enemy planes.
