Haus des Meeres is an aquarium and terrarium built inside a WWII flak tower in Mariahilf. The tower itself is a stark concrete anti-aircraft fortress from 1944, and the contrast between the brutalist exterior and the tropical fish inside is surreal. The shark tank, the tropical house (with free-flying birds and crocodiles), and the monkey section are the highlights. But the real reason to visit is the rooftop: 360-degree panoramic views of Vienna from a platform on top of the tower, with a cafe and bar. EUR 11 adults, EUR 6 children. The tower exterior still has original WWII-era murals and a climbing wall.
EUR 11 adults, EUR 6 children. The aquarium is fine but not world-class. The real reason to go is the rooftop: 360-degree Vienna views from the top of a WWII flak tower, with a cafe. The exterior still has original wartime murals. The tropical house with free-flying birds is a hit with kids. Takes about 1.5-2 hours. The building itself is the most interesting part.
