House of the Sea

Diving in

There is always something new at the House of the Sea: As of September 2021, over 1,000 fish – reef sharks, rays, tangs, damselfish, cleaner wrasses and more – are cavorting inside the new 360° shark tank on the 7th floor. With a size of 120 m², the largest tank in the House of the Sea (and in Austria!) is accessible from all sides and a “glass-only” aquarium. It enables views that make you feel like you’re diving. The old shark tank on the 4th and 5th floors is now used as a rearing tank.

A huge addition that was completed in 2020 is the new home of four fluffy kattas and two lemurs. Visitors (with reservations) can even get into close contact with the cute monkeys. This so-called Madagascar area, with its indoor and outdoor spaces, is also home to a fine-striped mongoose, a giant tortoise and three Komodo dragons.

Strolling through the Atlantic

On the ground floor, visitors can walk through the ten meter-long Atlantic Tunnel: the tunnel leads through a 500,000-liter tank, which is home to the fish of the Atlantic Ocean – ranging from damselfish to eagles rays and a nurse shark.

Crocodile Park to Surf Reef

In the Tropical House and in the Crocodile Park – both a spectacular 20 meter-high glass annex – you an look forward to free-flying birds and free-roaming monkeys, crocodiles and other animals attributable to the biotope. In the terrarium section live poisonous as well as giant snakes, lizards, leaf-cutter ants, and tarantulas.

And the Adventure Aquarium "Brandungsriff" lets children experience the tropical fish right up close through the "diver‟s helmets" built into the floor of the aquarium. In an artificial stalactite cave grotto, you can observe over 100 animals and cave-dwellers which are active by night: poisonous giant millipedes, amplypigids and armored ground crickets, cave fish without eyes and scorpions that glow like ghosts under UV light.

Feeding programs and guided tours

To the current start times

  • “Grasping” nature – “grasping” in the true sense of the word: Who wants to touch a shark’s tooth or find out how its skin feels without any danger? Or look deep inside the mouth of one of the famous, notorious piranhas? Or know what a tortoise shell looks like from the inside and how it is structured?
  • Shark diving
  • Shark feeding
  • Piranha feeding
  • Reptile feeding
  • “Mini-ocean” microscope show (jellyfish babies, starfish eyes, sting worms with needles filled with poison, one-eyed cyclops crustaceans and more)
  • Gharial feeding (gharials belong to the crocodiles)
  • Safari in the House of the Sea (guided tour)

Remembering inside

The exhibition "Remembering inside" is concerned with the dark history of the anti-aircraft tower. It includes original exhibits and boards on the building’s history, and is displayed in the stairwell between the 9th and 10th Floors, which has largely been kept in its original state. Guided tours take place daily at 11 am and 4 pm.

View of Vienna

Something special also awaits you on the roof: there's a breathtaking all-round view of Vienna from the 360° Ocean Sky Restaurant & Bar on the 11th floor. It is the highest of all the rooftop locations in the center of Vienna!

Another attraction is the panoramic view of Vienna's sea of houses from the roof terrace. Athletic visitors can climb the 192 steps of the tower stairs on the outside to enjoy the view from a height of 35 meters, independent of a trip to the zoo.

In the following video: the sea turtle “Puppi” is getting pampered. Off to the pool with the zoo director!
