Tiergarten Schönbrunn

Tiergarten Schönbrunn – Schönbrunn Zoo – was established by the Habsburgs in the park of Schönbrunn Palace in Vienna’s 13^th district of Hietzing in 1752 and is today the world’s oldest zoo that is still in operation. Zoologist Stephan Hering-Hagenbeck has been the zoo’s director since 2020. Schönbrunn Zoo has been recording more than two million visitors every year since 2006. It presents around 7,800 animals from 700 species on an area of 17 hectares. Anthony Sheridan’s zoo rankings recognised Schönbrunn Zoo as the best zoo in Europe five times in a row (2008, 2010, 2012, 2014, and 2018).^[1]

History[]

From 1745: the Emperor’s Menagerie[]

Schönbrunn Zoo was the brainchild of Franz Stephan of Lorraine, the husband of Maria Theresia. Franz Stephan, who had been elected as Franz I, Emperor of the Holy Roman Empire of German Nations, in 1745, commissioned the architect Jean Nicolas Jadot de Ville-Issey to design a menagerie in the park at the Habsburg-Lorraine’s new summer residence in Schönbrunn.

Twelve enclosures were created at the park, each with equally sized structures for the animals, and an administration building with a front garden. A pond and two yards were added later. The menagerie was presented to guests after around one year of construction in the summer of 1752. The last section to be completed was the octagonal pavilion at the heart of the site, which was laid out as a breakfast and social room in 1759. It still constitutes the zoo's historical centre to this day. It has been used as a restaurant since 1949.

The menagerie was initially reserved for the imperial family but school classes were subsequently also permitted to visit the zoo along with the diplomats and private guests. The menagerie, the palace and park were later opened to ‘decently dressed persons’ – but at first only on Sundays – in 1778.

From 1770: the first animals[]

The first elephant arrived at Schönbrunn in 1770 and wolves and bears were the first predators to find a home here in 1781. The first polar bears, big cats, hyenas and kangaroos arrived along with another pair of Asian elephants in around 1800. The exotic animals drew in the crowds – they attracted visitors to the imperial menagerie from Vienna and the surrounding areas as well as many guests from other countries. By then, the zoo was already opening to visitors on a daily basis and the first detailed descriptions and ‘zoo guides’ were being written.

Schönbrunn received its first giraffe as a gift from the Viceroy of Egypt in 1828. Its arrival triggered a genuine craze and influenced fashion, handicrafts and social life in Vienna. Clothes, shoes and utensils with giraffe motifs, hairstyles, a perfume, a play and two compositions ‘à la giraffe’ were created.

From the end of the 19^th century: most beautiful zoo under Alois Kraus[]

The menagerie’s look changed significantly towards the end of the 19^th century. Alois Kraus, who headed the zoo from 1879 to early 1919,^[2] rearranged the historic grounds to make them more suitable for the animals and easier for the public to visit.

Animal enclosures and farm buildings were newly built or modernised and the zoo was extended towards the east and south. Schönbrunn, with its almost 3,500 animals and more than 700 species, including elephants, rhinos, hippos, tapirs, giraffes and seals as well as many species of big cats and bears, had already come to be regarded as one of the most beautiful zoos in the world by the beginning of the 20^th century.

The first elephant to be conceived in a zoological garden was born at Schönbrunn in 1906. The complex remained the private property of the imperial family until the end of the Austro-Hungarian monarchy.

From the beginning of the 20^th century: world wars, nature conservation under Otto Antonius[]

Only 400 animals survived World War I due to supply shortages and associated hygiene problems. The zoo was only able to survive as a result of the residents of Vienna organising a relief campaign and making donations of animals and materials.

Otto Antonius, who headed Schönbrunn Zoo from 1924 to 1945, was the first director who was also a biologist. His tenure saw the number of animals at the zoo increasing to more than 3,000 by 1930. He also introduced the idea of breeding endangered species for conservation. He involved himself in raising awareness among the general public, promoted nature conservation and intensified the increasingly important contacts to the media, universities and museums. Lively scientific exchanges became the order of the day. The term ‘menagerie’ was officially replaced with the term ‘zoo’ in 1926.

The zoo had suffered aerial bombing attacks at the end of World War II that destroyed and damaged many of the animal enclosures and more than one thousand animals died. The Soviet and later the British occupation forces helped with the reconstruction following the end of hostilities.

From 1945: reconstruction and expansion[]

Julius Brachetka, who headed the zoo from 1945 to 1958, revived public interest in it with entertaining appearances in the media that were frequently accompanied by animals from the zoo. It was in keeping with the new spirit of the times. The first posters were created and photo competitions were held. A new aquarium and terrarium building was opened in 1959 to replace the one for the ostriches and reptiles that had been damaged during the bombing. It was one of the most modern such buildings in the world.  

Walter Fiedler, who headed the zoo from 1967 to 1987, doubled the zoo’s original area to 12 hectares with the conversion of the former Kleinen Fasangarten (Little Pheasant Garden) to the east. Other milestones included the opening of a children’s zoo in 1969 and the establishment of an education department at the zoo in 1976 – one of the first in Europe.

From 1970: image problems, spin-off with Helmut Pechlaner[]

This period was marked by increasing image problems for the zoo and declining visitor numbers in spite of its great breeding successes. The criticism of outmoded animal husbandry reached its peak in the late 1980s. Discussions about the dissolution of the zoo or a relocation to another district in Vienna ended in 1991. The zoo was subsequently spun off from administration by the federal government as Schönbrunner Tiergarten-Ges.m.b.H. – but the Republic of Austria remained the sole shareholder. Veterinarian Helmut Pechlaner, who hailed from Tyrol and who had, until then, been director at the Alpenzoo Innsbruck (Alpine Zoo), was appointed the sole managing director.

With the support of the Republic of Austria, numerous donors and sponsors as well as new admission fees, Helmut Pechlaner was able to modernise and expand almost all of the enclosures. The first construction project to be completed was the small monkey house in 1992 with two ‘monkey islands’ in the baroque pond as an outdoor enclosure that is now home to ring-tailed lemurs and gibbons. The zoo was extended to the south with a section from the Vienna Woods. The Tirolerhof (Tyrolean Farmyard), a new elephant park, the modern big cat enclosure, an enclosure for giant pandas, an insectarium and one of the largest rhino enclosures in Europe were created. The two Indian rhinos that arrived in 2006 were a gift from the former royal family of Nepal. The animals had been picked up as orphans and it had not been possible to reintegrate them into the wild.

The ensemble of Schönbrunn Palace, Zoo and Palace Park was declared a UNESCO World Heritage Site in 1996. The same year saw the unveiling of the first large bronze sculpture by Gottfried Kumpf: a lion. More bronze sculptures that remain a popular photo motif to this day were added over the following decades. The Rainforest House was opened to celebrate the zoo’s 250^th anniversary in 2002, which was also the year in which the first koalas arrived at Schönbrunn and the panorama railway experience was opened.

From 2006: visitor records and Best Zoo in Europe[]

Dagmar Schratter succeeded Helmut Pechlaner on 1 January 2007 and filled the position of the zoo’s sole managing director until the end of 2019. Her tenure stood out for the five awards that recognised the zoo as the best in Europe, the five giant panda cubs that were born there and the record year of 2008 during which the zoo recorded a total 2.6 million visitors. Stephan Hering-Hagenbeck, who previously worked at Tierpark Hagenbeck (Hagenbeck Zoo) in Hamburg, was introduced as her successor in autumn 2019.^[3] He assumed the role in January 2020.

Giant pandas[]

Schönbrunn Zoo is one of the few zoos in Europe that is able to boast giant pandas as an attraction. The female Yang Yang (阳阳 ‘Sunshine’) and the male Long Hui (龙辉 ‘Sign of the Dragon’) arrived in Vienna in 2003 and became sensations for their successful breeding.

Yang Yang gave birth to the first baby panda – a male – to be conceived naturally and not by artificial insemination in Europe on 23 August 2007. In accordance with traditions in China, it was named 100 days after its birth: Fu Long (福龙, ‘Happy Dragon’).^[4] The second baby panda, also a male, was born at Schönbrunn exactly three years after Fu Long's birth on 23 August 2010.^[5] It was named Fu Hu (福虎, ‘Happy Tiger’). A third panda cub, another male, was born on 14 August 2013.^[6] It was named Fu Bao (福豹), which means ‘Happy Leopard’. These animals were followed by twins, which were born on 7 August 2016,^[7] and named Fu Feng (福凤 ‘Happy Phoenix’) and Fu Ban (福伴 ‘Happy Companion’). Yang Yang was the first panda in captivity to raise twins without the help of her keepers.

The cubs were transferred to China to zoos or panda breeding stations at the age of two. Long Hui passed away in December 2016 as a result of a tumour. A new male panda, Yuan Yuan, arrived at the zoo in April 2019.^[8]

Worlds of experience[]

‘Franz Josef Land’ – the world of polar bears[]

The five-metre-deep plunge pool at the World of Polar Bears, which opened in 2014, allows visitors to see polar bears swimming underwater. The facility is 1,700 square metres large. The name is a tribute to the successful exploration of the Arctic achieved by Austria-Hungary in the past. The visitor centre, known as the Polar Dome, has been designated an ‘Arctic Ambassador Centre’ by Polar Bears International.^[9]

Polarium[]

The glazed 13 metres of pool permits visitors to watch South American sea lions swimming. At feeding time, the animals climb on to the rocks and jump into the water to catch the fish as they are thrown into the water.

The seasonal light and climate conditions of native habitats are simulated for the king penguins and northern rockhopper penguins: around 10°C room temperature and 8°C water temperature.

Rainforest House[]

The Rainforest House was opened in the year of the zoo’s 250^th anniversary. The Glass House presents a section of a mountain slope in a rainforest in south-east Asia. This is where, among others, the rare northern river terrapin, oriental short-clawed otters, various species of birds, flying foxes, pythons and Fiji banded iguanas live. Sophisticated environmental systems ensure that temperatures don’t fall below a minimum of 25°C and that the humidity doesn’t fall below 80% at any time of the year.

Zoo ORANG.erie[]

The first Palm House, which was built in the 19^th century under Emperor Franz I and used as a film studio from 1920, was revitalised in 2009 and has been home to the orangutans since then. Reproductions of the works by Nonja, a female orang-utan, are on display at ‘Atelier Nonja’, the adjacent café-restaurant. Nonja is famous for the paintings she produced with the paints and brushes she was presented with to occupy her in the 1990s.

Insectarium[]

The house was opened in 2005 and presents insects that are masters of camouflage and deception in 14 terrariums.

Aquarium and Terrarium House[]

This building is entered through the crocodile pavilion. This is where, among other things, the Seychelles giant tortoise that are more than 100 years old live. This building is where aquariums are located with piranhas, lionfish, moray eels and rays as well as a large coral reef with hundreds of fish from the Indo-Pacific. Four jellyfish Kreisel have been created so that visitors can always see different types of jellyfish. Schönbrunn Zoo is home to the most species of jellyfish in the world. A tunnel aquarium with arapaimas takes visitors into the terrarium building where snakes, iguanas and other such rare reptiles as shingleback lizards live.

Pet Park[]

The Pet Park explains what rabbits, budgerigars and bearded dragons need when they are kept as pets.

Nature Discovery Trail[]

The treetop path leads from the zoo’s Tirolerhof (Tyrolean farmyard) up 10 metres into the tree canopy to enable visitors to observe the native species of birds. The forest path continues past outdoor terrariums with common European adders, horned vipers and native amphibians. The world of native fish is presented in large aquariums in the ‘Am Wasser’ (At the Waterside) section.

South America Park[]

Giant anteaters, capybaras, Brazilian tapirs, Vicuñas, seriemas and greater rhea live together in the South America Park. The outdoor area has been laid out to resemble a pampas landscape with hills and ponds.

Tirolerhof (Tyrolean Farmyard)[]

The Haidachhof, a two-storey Lower Inn Valley single-structure farm that dates back to 1722, is a listed building that was dismantled at its original location in Brandenberg in Tyrol and rebuilt at the zoo. Endangered breeds of farm animals such as Tux-Zillertal, Pustertaler Sprinzen, Noriker horses, Carinthian sheep, Original Braunvieh, Tauernsheck goats and Sulmtaler chickens have been kept here in the stables since then.

Big Cat House[]

The Big Cat House leads to the indoor enclosures where the leopards and Siberian tigers live. Each species is able to enjoy a large landscaped outdoor area adjacent to the building that features raised platforms, ponds and shrubs for concealment. The cheetah enclosure is often cited as an example of Helmut Pechlaner’s ingenuity. He had the asphalted visitor area converted into an outdoor landscape in 1994 that allowed visitors to observe the animals from the old cages.

Birdhouse[]

Two open-air halls each present different landscapes and their native wildlife: the African savannah with pencil trees, southern red bishops and African jacanas, and the South American tropics with tanagers, purple honeycreepers and blue-backed manakins in a lush jungle of plants. The central hall is home to the sloths.

Rat House[]

The Rat House is home to fancy rats, northern giant pouched rats and northern luzon giant cloud rats. Special lighting technology has been installed to adapt the rhythms of the day and night so that visitors may observe the nocturnal rodents climbing, bathing and burrowing.

Monkey House[]

The historic building, which dates back to 1841, underwent a general renovation in 2012 after two previous conversions (1906, 1930) and is home to king colobus, meerkats, red ruffed lemurs, pygmy marmosets, squirrel monkeys, emperor tamarins, Goeldi’s marmosets and white-headed marmosets.

Rhino Park[]

Two Indian rhinos live on 6,000 square metres along with such other Asian species as nilgais, indochinese sika deer and blackbucks.

Giraffe Park[]

The historic Giraffe House was restored in 2017. A winter garden was added in accordance with conservation requirements to the rear of the building for the purposes of providing more space for the giraffes during the winter months. The photovoltaic system that has been incorporated into the glass roof produces all the electricity that the enclosure requires. A layer of gravel in the basement converts the heat that accumulates during the day into night-time heating. The zoo was awarded the City of Vienna’s environmental prize for the utilisation of these technologies.

East Africa House[]

The East Africa House is home to smaller species of animals from the same habitat that is occupied by the giraffes: dwarf mongooses and Von der Decken's hornbills, which forage together in the wild, and southern ground hornbills, which live in the same outdoor enclosure as the giraffes.

Desert House[]

The Desert House is located at the zoo’s entrance gates opposite the Palm House. A circuit trail leads through a desert habitat with rattlesnakes, naked mole-rats, colourful birds and other creatures of the desert. The botanical focus is on the cacti and other succulents.

Wildlife conservation and research[]

Schönbrunn Zoo participates in international breeding programmes for the purposes of wildlife conservation. It is responsible here within the scope of the EAZA Ex-situ Programme for maintaining the studbook for the southern and northern rockhopper penguins as well as the Fiji banded iguana.^[10]

Giant pandas – wildlife conservation project[]

Schönbrunn Zoo cooperates with the China Wildlife Conservation Association (CWCA) in its efforts to protect giant pandas. Joint research activities, conservation breeding, regular training courses, the establishment of panda reserves and the reforestation of bamboo forests are regarded as some of the most important pillars of the project.

Northern bald ibis – wildlife conservation project[]

Schönbrunn Zoo is a partner to the team that is working within a European Life+ project to reintroduce the northern bald ibis, which is a highly endangered species, to central Europe.^[11] These birds’ chicks that are hatched in zoos and wildlife parks are imprinted on human foster parents, who then use ultralight aircraft to teach the birds how to navigate to suitable overwintering quarters.

Northern river terrapin – wildlife conservation project[]

Northern river terrapins belong to the three rarest species of turtle in the world. Schönbrunn Zoo was the first to successfully breed these terrapins in captivity in 2010. The zoo has – in addition to its important breeding efforts – also initiated a rescue mission in Bangladesh.

Polar bears – wildlife conservation project[]

The zoo supports ‘Polar Bears International’ (PBI), an initiative to save polar bears. The PBI researches how polar bears live in their native habitats. Transmitters are fitted to animals in the wild to track their migratory routes, which have changed due to the disappearing pack ice.

Barbary apes – wildlife conservation project[]

The zoo also supports the Barbary Macaque Awareness and Conservation (BMAC) wildlife conservation project in Morocco, which, among other things, runs educational programmes and is working to reintroduce illegally captured Barbary macaques to the wild.^[12]

Brasilian tapirs – wildlife conservation project[]

As part of a research project in the Pantanal in South America, collar transmitters provide information about what tapirs need to survive. The project also keeps local residents informed about the animal world.

Pond turtles – wildlife conservation project[]

European pond turtles are the only species of turtle that is native to Austria. The zoo is working with the Donau-Auen National Park, where the last intact population in Austria lives, to protect the clutches.

Bearded vultures – wildlife conservation project[]

Bearded vultures were wiped out at the beginning of the 20^th century. Animals have been successfully reintroduced from breeding programmes such as those that have taken place at Schönbrunn Zoo since the 1980s.

Ural owl – wildlife conservation project[]

Habitat loss resulted in the extinction of the Ural owl in Austria. Living conditions have improved again and so a decision was made to launch a reintroduction project, which Schönbrunn Zoo is supporting with, among other things, chicks from its breeding programmes. Several hundred birds have already been released into the wild.

Zoological, historical and veterinary research is also carried out at the zoo – mainly in cooperation with the University of Veterinary Medicine Vienna and the Department of Evolutionary Biology of the Faculty of Life Sciences at the University of Vienna.

Significant breeding successes[]

The five Giant Panda cubs were the first in Europe to be born as a result of natural conception. Yang Yang was the world’s first panda in captivity to raise twins without help from her keepers.^[13]

A female anteater was also able to successfully raise her twins for the first time in the world at a zoo in 2000.

The first elephant calf to be conceived with the help of artificial insemination using frozen semen was born at the zoo in 2013.^[14]

Schönbrunn Zoo is the only zoo in Europe to successfully breed the endangered northern rockhopper penguins every year.
