Vienna had to deal with a lot of problems post WWII, including what to do with the huge flak towers. Fortunately for us, they turned one into a giant aquarium center: the Haus des Meeres.
- Over 10,000 fish, reptiles, amphibians, birds and mammals
- Diverse range of displays, including some pretty mammoth fish tanks
- Highlights are the sharks and the multi-level tropical house with its free-spirited monkeys
- The roof terrace has outstanding views of Vienna (also accessible separately)

Inside the Haus des Meeres
Vienna’s flak towers were giant concrete blockhouses with 3.5m thick walls, built to house air defences to counter bombing raids by the allied forces.
Too big to easily demolish, the flak tower in Esterhazy Park now houses the Haus des Meeres; 12 floors of watery entertainment. The literal translation is House of the Sea, which gives you an idea of what to expect.
At its core, it’s an aquarium and vivarium, with numerous glassed displays. But that undersells it.
The Haus des Meeres is not just row after row of identikit tanks. Instead, its tanks come in all sizes and shapes, from tunnels to giant, two-storey showpieces.
The contents of each display cover themes rather than just different types of animal. So you might have a tank with a rock pool ecosystem or one illustrating symbiosis.
Added to that are the walkthrough enclosures: a small crocodile park and the multi-level tropical house with rope bridges and free-roaming bats, birds and monkeys. I’ve put my fish and animal highlights in a separate article.
And the dollop of whipped cream on the aquarium pie is the top floor Ocean Sky restaurant and terrace with a 360° panorama across the entire city – one of the best places to get views of Vienna.
A lot of love clearly goes into the facility. It’s full of bright colours, well-maintained displays, and friendly staff. You’d expect a flak tower to be dingy, but it’s quite the opposite.
The Haus des Meeres also does a marvellous job with the space available. It’s not nearly as cramped as you might imagine, though nor can you expect wide watery vistas. Some of the floors do have only a very few displays, with the rest of the space given over to offices, storage rooms and similar.
All in all, it’s an excellent way to kill an hour or two, particularly in wet weather and particularly if you have kids. Since it’s located just off one of Vienna’s major shopping streets (Mariahilfer Straße), you can combine a trip with a retail expedition.
Tickets & visitor tips
(The old rooftop design of the flak tower)
Get your tickets direct from the Haus des Meeres. At the time of writing, a standard adult entrance ticket cost €19.90, with various concessions.
A few tips and notes:
- There are two places to eat and drink in the tower:
- Cafe Sharky: a small, self-service café
- Ocean Sky: a bar and restaurant with table service on the very top floor. This is the place with the views (I had coffee there recently and enjoyed the experience immensely)
You don’t need a ticket to the actual Haus des Meeres to visit the Ocean Sky restaurant and viewing terrace. A separate Panorama Lift in the entrance foyer takes you up there.
At the time of writing, there is no charge for the lift but the plan is to make it ticketed at some point (the cost of the ticket will be taken off your restaurant bill).
- Almost all information is in both English and German
- Don’t be shocked, but the Haus des Meeres ground floor shop sells…wait for it…quite a lot of toy animals, mostly stuffed or plastic. So see your shark, then take one home with you.
- A lift takes you everywhere. My tip: take the lift once up to the top, then walk down the stairs visiting each level as you go.
- You can leave coats and bags on free-standing racks behind the shop on the ground floor. Or get a smallish locker with a 50 cent coin
- Don’t rush to the lift and stairs once through the ticket barrier – the ground floor already has some memorable exhibits: an aquarium tunnel and fish to stroke, for example.
- An ongoing expansion project will add more animal displays and improved visitor facilities, so expect to see even more over the next year or two.
