Haus des Meeres, Public aquarium and zoo in Mariahilf, Austria.
The Haus des Meeres spans eleven floors in a concrete tower, housing over 10,000 marine creatures, tropical animals, and a diverse collection of reptiles.
The thick walls were built during World War II as a military defense structure. Twelve years after the war ended, the tower opened its doors as an aquarium.
The facility contributes to Vienna's educational landscape by offering specialized courses in reptile care and conducting research on marine species conservation.
Located near Mariahilfer Strasse, the facility provides extended visiting hours on Thursdays until 21:00 and includes a rooftop restaurant with panoramic views.
On the outside, only a few details hint at the original purpose, while inside the concrete construction remains visible. On the roof, an open area allows views over the city rooftops.
