What do you think about these WW2 anti aircraft towers in Vienna? These two are in Augarten. Should they be preserved or even turned to a museum?

There is one in 6th district that actually houses a public aquarium. As far as I know, removing them wouldn’t be that easy, as they are pretty sturdy, to say the least.

Reviews Summary

Visitors are impressed by the sheer size and historical significance of the WWII flak towers in Augarten Park, noting their remarkable preservation. While not a primary tourist attraction, their unique architecture and imposing presence make them a surprisingly impactful discovery for those who seek them out.

"A very interesting structure from World War II. Built to protect part of Vienna from air raids. The thickness of the walls allowed hundreds of people to safely remain inside the tower. It's a shame they didn't incorporate an observation deck."

Oleksandr Lastovetsky

"I loved it!
Same structures as in Arenberg Park: huge concrete towers which were built during World War II to serve as anti-aircraft blockhaus.
They also served as shelters for tens of thousands of people (!).
I wouldn't say it's a must-see in Vienna, but it's so special and unusual that I highly recommend a visit, if only to be impressed by its size and unique architecture.
Look at the photos."
