House of the Sea

Austrias largest aquarium is located in the House of the Sea: A 300,000 liter tank holds black and white tip sharks, bamboo sharks, and Puppi, a sea turtle. Another highlight is the 150,000-liter tank for the hammerhead sharks on the tenth floor of the former anti-aircraft tower. On the ground floor, visitors can walk through the ten meter-long Atlantic Tunnel: A 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. And the café on the 11th floor grants visitors a breathtaking view of Vienna.

And the House of the Sea is known for constantly coming up with new things. A huge annex completed in autumn 2020 is the new home for four fluffy ring-tailed lemurs and two lemurs. Visitors can even get in close contact with the sweet little monkeys. Registration and information on tel. +43 664 54 40 820. This so-called Madagascar area, which has an indoor and outdoor area, is also the home of a narrow-striped mongoose and a giant tortoise. With the completion of the new building, the three komodo dragons of the House of the Sea have also moved onto the 9th floor.

Something special is also waiting up on the roof: From the 360° Ocean Sky Restaurant & Bar on the 11th floor there is a breathtaking panoramic view of Vienna. It is the highest-situated of all rooftop locations in Vienna city center!

New: Private Guided Tour for up to 8 visitors

Say hi to your favourite animals, discover new highlights of our zoo and of course get the inside scoop and fun anectodes from schooled guides. The tour (~60 minutes) takes place Friday, Saturday or Sunday at 6.30 pm, reservations only. Booking per Mail or per phone 0664 544 08 20. The tour price for the whole group is 100€ ex. entry.

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 - You can grasp nature in the truest sense of the word:

  • Who would like to touch a shark's teeth in complete safety or know what its skin feels like?
  • Who would like to look deep into the mouth of the famously infamous piranha?
  • Who would like to know what a tortoise shell looks like from the inside and how it is structured?

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

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.
