Vienna flak tower

I'm quite impressed. Standing in a former flak-tower ( scroll down a bit ), that has been converted to a big vivarium/aquarium. I can blog from here, it has a free internet access. I could watch one of my favorite animals, pythons of various kinds. And they closely bring together humans and a ton of birds and small apes. Quite interesting, I recommend "Haus des Meeres" in the old flak tower in Vienna.
