Basel is a non-profit zoo in the city of Basel, Switzerland. Its
official name is Zoologischer Garten
Basel — or in English: Basel
Basel residents affectionately call it Zolli.
Its main entrance is just outside Basel's downtown strip of Steinen
and extends in the
Birsig stream valley to Basel's city border with
Basel is Switzerland's oldest (1874) and largest zoo (by number of
animals). With over 1.8 million visitors per year, it is the
most visited tourist attraction in
Switzerland with an entrance
Basel was ranked as one of the fifteen best zoos in the world by
Forbes Traveler in 2008 and in 2009 as the seventh best in Europe
by Anthony Sheridan from the Zoological Society of London.
The zoo had the first
Indian rhinoceros birth in a zoo, as well as
the first greater flamingo hatch. It has had repeated breeding
success with animals including cheetahs (18 births), okapi
(22), pygmy hippopotamuses (53), and flamingos (over 400
Somali wild ass
Somali wild ass (a donkey) in zoos worldwide is
related to the population in Basel, where this species' zoological
breeding program was started.
Basel is undergoing the most expensive expansion in its history.
These include the indoor and outdoor renovation of the monkeyhouse
(2011-2012 / Fr. 30 millions), the zoo restaurant renovation/expansion
(2015 / Fr. 16 millions), a new elephant house and outdoor exhibit
(2016 / Fr. 28 millions), and a new large-scale aquarium (2019 /
Fr. 60-80 millions).

Exhibits and attractions
Zoo Basel's main entrance
Basel is surrounded by the city of
Basel and has a similar role to
the local population as does the
Central Park in
New York City
New York City for the
city's residents. According to
Zoo Basel, its "exhibits are designed
not to reveal everything at the first glance and are planned to invite
visitors to stop and make personal observations."
Listed below are some of
Zoo Basel's exhibits. Note, however, that
exhibits continually change due to infrastructure upgrades, breeding
successes, and the construction of new exhibits.
The aquarium (called Vivarium in Basel) was opened in 1972 and has had
several notable breeding successes through the years. These include
lungfish bichir offspring in 2006, repeated king penguin
hatches, and over a thousand hatches of the red-bellied
short-necked turtle since 1981.
As of May 2012, there were about 6,000 animals in the Vivarium in 480
species, including fish, reptiles, amphibians, gentoo penguins,
and king penguins.
During the winter months, the gentoo and king penguins have access to
an outdoor area and can be observed walking from the Vivarium to it
every morning around eleven.
Hippos, ostriches, and zebras (Grant's zebra) live together in the
Africa exhibit was
Zoo Basel's first in which three species share
the same outdoor area. According to the zoo, experiences gained in
this exhibit helped shape the
Etosha theme area and the rhinoceros
It was completed in 1993 and has been scene of several accidents. On
October 13, 2004, after twelve years of living together, the
17-year-old zebra mustang bit the hippo male during its daily morning
territory marking, the zebra fell into the water, and was killed by
the hippos in front of several visitors.
On February 13, 2013,
Basel reported that the ostrich couple
Baringo (b. 1993) and Manyara (b. 1992) had yet another ten chicks.
According to its webpage,
Basel "is especially proud that the
ostrich parents are very successfully natural breeders." While Manyara
was sitting on the eggs during the day, Baringo took over the night
shifts. Without human breeding help, about 110 ostriches have hatched
Basel since 2000.
Basel first acquired kangaroos in 1908. Since then, over a hundred
kangaroos have been born. In 2006, the theme area Australis was
opened, funded by Novartis. In this outdoor exhibit, western grey
kangaroos and Australian brush-turkeys live together. Inside the
Australis house are several vivaria exhibiting Australian animals,
including geckos, redback spiders, cane toads, several species of
Phasmatodeas (or stick insects), and green tree pythons. An
educational exhibit inside the house focuses on marsupial
Bird House entrance logo
The Bird House opened in 1927 and is the second oldest building in Zoo
Basel. While in the early days this house used to have reptiles and
monkeys, it now has only birds.
The 'jungle' in the center of the bird house has free-flying birds,
who can hide in the thick vegetation. Some like the
Knysna turaco can
be heard but are only visible in flight.
Since 1948 the zoo has hosted birds belonging to the
family. The small montane white-eye bird, that belongs to this family,
came in 2008 again to Basel, after 20 years of absence.
Meerkats by the
The opening of the
Etosha theme area in 2001 started the
implementation of the large theme area concept of modern zoos at Zoo
Basel. The exhibit consists of the
Etosha house, outdoor exhibits for
the cheetahs, African wild dogs, ring-tailed lemurs, Cape porcupines,
and the lions, as well as the Gamgoas house. They build a theme area
around the African circle of life.
Etosha exhibit was named after the
Etosha National Park: the
largest national park in
Namibia and in the southwest of Africa. It is
about half the size of Switzerland.
Nile crocodile enclosure
Gamgoas is part of the
Etosha theme area, but it refers mainly to the
lion and crocodile house. Gamgoas's literal meaning in the local
language of the
Etosha people is "the place where the lions are."
In the Gamgoas house are two colonies of termites, one chameleon, five
Nile crocodiles, several dozen East African cichlids (fish), a
semi-large information exhibition, and three lion observation windows.
A large window at the
Nile crocodile enclosure allows visitors to see
the crocodiles under water and to be within an inch of them.
On June 20, 2006 several Nile crocodiles hatched for the first time in
the zoo's history. Two of these new crocodiles grew up in the zoo
and are now among the five Nile crocodiles at
The monkey house (built in 1969) is the zoo's largest building and has
had several breeding successes, such as the first gorilla baby in
Europe (Goma), the first second-generation zoo gorilla in the
world (Tamtam), and rare white-faced saki babies.
On June 30, 2011, the
Monkey House was re-opened after extensive
renovations and expansions with all monkeys back — except the
orangutans and the woolly monkeys, which "came back" in 2012. The
30-million Swiss franc project was completed in the fall of 2012
with the opening of the outdoor exhibits, which are now about thirty
times larger than before. More information on this project can be
viewed at Developments at
Rhinos in the outdoor exhibit
The Sauter Garden is at the zoo's south end towards Binningen. The
land was acquired with money from the local goldsmith Ulrich Sauter
and opened to the public in 1939.
The Sauter Garden's focus is on Asia. While African species (like the
pygmy hippopotamus and the Humboldt penguin) are also in it, its main
exhibits are of Asian animals: the Indian rhinoceros, snow leopard
exhibits and, as of June 2010, the "
Monkey Rock" with about 60
macaques on/in it.
In the rhinoceros exhibit, Indian rhinoceroses, muntjacs, and oriental
small-clawed otters share the outdoor area. Since then, the three
species lived together with no incidents. The 2.5-ton-rhinoceroses
share their food with the 30-kilogram muntjacs or go into one of three
ponds where the Asian otters are swimming around the rhinos. The rhino
exhibit originally opened in 1959, was extensively renovated, and
re-opened in May 2008.
The snow leopard exhibit houses Mayhan and Pator. Both arrived in the
winter of 2008/2009 and had three cubs during the spring of 2011. As
of June 2011, 30 snow leopards were born in Basel.
Special opening days
June 24 — Beck Day: In memory of Johannes Beck, the zoo's first
Basel is open until 10 pm. After 4 pm, entry to the
zoo is free of charge. Each year the 'Beck Day' has special
attractions and events, like the
Basel gypsy-jazz group BELLEVILLE in
2008, special lunch packages from the Swiss retailer Coop, and the
traditional placement of a flower bouquet at Johannes Beck's memorial
in the zoo.
Zolli night: Some days, the zoo stays open until midnight. The entry
price is reduced after 5 pm. Among the attractions are several meeting
points where every half hour zoo officials give insights of the
exhibit and animals that live in it. The dates for this event are
different each year and, once set, can be found in the local media and
Zoo Basel's official website. In 2010, it was on June 26, with an
opening until 11pm.
Main article: Breeding programs at
Basel is a member of the World Association of Zoos and Aquariums
European Endangered Species Programme
European Endangered Species Programme (EEP), and 18 other
programs and organizations. In 1935, the forerunner of the WAZA (the
International Union of Directors of Zoological Gardens or IUDZG) was
founded in Basel.
Among the breeding programs for endangered species that
participates in are the pygmy hippopotamus, Indian rhinoceros, okapi,
snow leopard, South African cheetah, squirrel monkeys, and the
European otter programs.
Immature South African cheetahs
Among 82 other European zoos with cheetahs,
Zoo Basel's breeding
program is one in a dozen that has repeated breeding success. Basel
had five young cheetahs born in 1993, 1995, and 2007, and three in
2009 of which one died that fall.
Cheetah breeding in captivity is difficult, as males and females live
separately in the wild and females are picky in choosing a partner.
The 30% mortality rate among newborns also lowers breeding success.
That is why the new pair of female cheetahs that came to
Basel in 2001
did not show interest in the presented males and had no offspring -
until "Survivor" came from Vienna in 2006.
Basel has held the international studbook for the Indian
rhinoceros since 1972, and since 1990 has coordinated the European
Endangered Species Programme (EEP), which ensures that the captive
Indian rhinoceros population stays as genetically healthy as possible.
One of the main reasons for
Basel to have these studbooks is due to
its successful breeding program.
Indian rhinoceros populations in zoos are related to the one in
Basel. On September 14, 1956, Rudra was the first Indian rhino born in
the Western Hemisphere. As of 2010, 32 Indian rhinos had been born in
Basel, out of about 80 rhino births in zoos worldwide,
Since the first okapi birth at
Basel in 1957, twenty-two okapis
have been born in Basel. On December 2, 2009, the okapi bull Stomp
(b. 2003) came from
Zoo Berlin and on August 24, 2011 the female
Hazima (b. 2007) arrived from the British Marwell Wildlife.
In 2008, Basel's Ahadi fathered the first okapi birth in the Czech
Zoo Dvur Kralove. A video of this birth is
posted on YouTube.
Basel started its breeding program for pygmy hippopotamuses in
1928, which has resulted in 53 hippo births. These animals and their
offspring are living all over the globe. The zoo manages the
international studbook for this species.
Somali wild ass
Since the construction of the rhino exhibit, the pygmy hippos can only
be viewed in their outdoor exhibits. During the winter they are inside
and cannot be seen by the public.
Somali wild ass
This wild donkey (Equus africanus somalicus) is a subspecies of the
African wild ass.
Basel coordinates the European Endangered
Species Programme (EEP) of the Somali wild ass, which is on the Red
List of critically endangered species as there are likely less
than 3000 animals in the wild.
There are about 220 individuals in zoos around the globe of which 38
were born in Basel.
Main article: History of
In 1870, the Ornithologiegesellschaft together with the city of Basel
started a project of establishing a zoo where visitors could see Swiss
and European animals.
Basel emerged from that project, and opened
its doors on July 3, 1874.
1939: second entrance by Binningen
Early years up to 1910
On opening day, many visitors flocked to the zoo and saw mainly Swiss
animals, such as bears, lynx, otters, and mountain goats. In its
opening year the zoo had 62,000 visitors, even though the city of
Basel had only 50,000 inhabitants. In addition,
Zoo Basel's nickname,
Zolli, was established in its first year and used ever since.
In 1884, the Zolli nearly doubled its area from 4,3 ha by adding the
Sautergarten in the south towards Binningen and built a festival
meadow in its center. On this meadow people from Nubier, Marocco
and Singhalesen built traditional villages and performed war and other
ceremonial dances. These displays were very popular at the time, and
lasted until 1932.
In 1890, the first lions arrived in Basel, and on March 19, 1891 the
first lion cub was born. The carnivore house received several new
cages featuring other big cats in 1896. All of these cats were moved
into a newly built carnivore house in 1904.
1901 was the year in which the zoo received its first major donation
from Johannes Beck that served as a foundation for years to come.
Challenges and expansion: 1911 - 1948
The first and second world wars caused
Basel several challenges.
During World War One, food prices climbed enormously and visitor
numbers dropped. Because of this, the 'Friends of
Zoo Basel' was
established in 1919, with a goal to make the zoo popular and to
support it with animal and money gifts.
Foot-and-mouth disease broke out in 1937. The animal population was
decimated like never before seen in
Zoo Basel's history and the zoo
had to temporarily close its doors.

Zoo Basel's 75-year anniversary in 1949,
Basel and the city of
Basel developed jubilee plans that resulted in much construction
during the 1950s. A new lion house was built in 1956 (that stood until
the Gamgoas project), followed by a new elephant house and yet another
land expansion to the east, the Nachtigallenwäldli, in 1959.
In 1961, the main entrance was moved toward the
In 1966, the first African elephant, Ota, was born in Basel. Three
years later the monkey house opened.
In 1972, the aquarium, or vivarium, opened where several world-famous
breeding successes occurred, such as the successful breeding of sea
1986: second rhino outdoor exhibit
In 1992, another male
African elephant Pambo was born. That year also
marked a new
Basel exhibit era with the opening of the Africa
exhibit. For the first time, several species where living together.
Experiences gained with the
Africa exhibit served as example for
In 1999, the snow leopard exhibit moved into the Sauter Garden, which
is being transformed into Asia-themed area.
Recent years: since 2001
During the past years,
Basel focused on renovating and expanding
existing exhibits, mainly to combine them into larger theme areas.
This happened in 2001 with the
Etosha House and exhibit as the first
part of a larger African themed area. The second phase was opened in
2003 with the Gamgoas house.
In the years 2008 and 2010 the rhino exhibit underwent a major
renovation and expansion. First the outdoor exhibit was remodeled to
include 3 water ponds, an open flowing stream, and the addition of two
new species living in the same outdoor exhibit. Then, in 2010, the
renovated and expanded rhino house opened. The hippos no longer had an
indoor pond, the four rhino boxes were converted into two large stalls
with a soft, jungle-like, wooden floors and a bath was added.
In summer 2011, a new monkey rock in the Sautergarten opened, followed
by a renovated and greatly expanded monkey house that fall. A year
later, in September 2012, the ape outdoor exhibits opened — about
100 times larger than before construction.

Basel is constantly upgrading its infrastructure, but can hardly
grow in area, as it is surrounded by the city of Basel.
2014: Renovated and expanded restaurant
Zoo Basel, construction started in the fall of 2013 and
was partially completed by Easter 2014. Of interest will be a
large window on its side towards the elephant exhibit, additional
restrooms, and an additional "take-away" food shop. This project is
scheduled to cost 16 million Swiss francs, of which 8 millions are
secured through an anonymous donor.
2016: New elephant house
The current elephant house (constructed in 1953) is due to be
renovated and expanded. Planned are boxes for the females, a larger
outdoor male area, and overall expansion of the area towards the old
Because of the large donation for the monkey expansion project, Zoo
Basel is able to finance this project.
On June 21, 2012,
Zoo Basel's board of directors approved this
project. Under the theme "mobility," it is planned on the current
elephant exhibit, as well as on the old kangaroo exhibit, the
playground adjacent to the elephant house, and the lemurs exhibit.
On April 10, 2013,
Basel published following update:
"Construction work on the new elephant enclosure will begin in August
. It will cover around 5000 square metres, making it more than
double the size of its predecessor. The enclosure consists of various
partial outdoor enclosures and a new elephant house... Some of the
funding for this 28-million-franc project is already in place, with
the remaining ten million being sought through donations. The
enclosure is scheduled to open in the autumn of 2016. As well as
elephants, the zoo plans to house guinea fowl, white storks, harvester
ants and Norway rats."
2019: Ozeanium (additional aquarium)
Ozeanium on Heuwaage
On March 17, 2009,
Basel announced its intent to build
Switzerland's first large-scale ocean aquarium. Mainly through private
donors, a 70-million-Swiss-franc building is planned to be built
on the Heuwaage square and will extend into the downtown nightlife
strip of Steinen.
On December 4, 2012,
Basel published that construction is expected
to begin in 2016. Thomas Jermann, the project manager, said that it
"if everything goes according to plan, visitors can enter our Ozeanium
from 2019 on."
Notable residents – past and current
Miss Kumbuk (? – 1917)
Miss Kumbuk, was
Zoo Basel's first elephant. She was an Asian elephant
and arrived in 1891. For her the first
Basel elephant house was
Rdura was the first
Indian rhinoceros born in a zoo in 1956. He was
the son of rhino bull Gadadhar and the female Joymothi that came from
Kaziranga National Park. Two hours after birth he weighed 60.5 kg
and was 105 cm long and quickly gained 1.5 kilograms per day. In
1959, Rudra was transferred to the Milwaukee County Zoo, where he only
became a father once before his death.
Goma (1959 – )
Goma was the first gorilla born in
Europe (western lowland gorilla,
the second worldwide in a zoo) and was raised by zoo officials. On
May 2, 1972 she and
Jambo had the world's first second generation
zoo offspring: Tamtam (who died in summer 2009). She is the oldest
member of the gorilla group in
Basel (May 2010) and celebrated her
50th birthday on September 23, 2009 with a large public birthday
Jambo ( 1961–1992)
Main article: Jambo
Jambo was a western lowland gorilla born in Basel. He became a
celebrity sensation at the Jersey
Zoo where on August 31, 1986 he
cared for a 5-year-old boy who fell into the gorilla habitat. A video
of the fall is on YouTube and was watched nearly 700,000 times
before it was deleted in September 2009 and relisted. Two new movies
of this event have been watched over 280,000 times combined (May
Jambo died in 1992, a bronze statue in his memory erected
at the zoo and Gerald Durrell produced a video documentary called
Jambo — the Gentle Giant. Richard Johnstone-Scott wrote the book
Jambo — A Gorilla's Story.
Jambo was named by
Zoo Basel's director Ernst H. Lang and means in
Swahili “Hello” or “How are you?” Due to Basels Jambo,
apes across the globe are called "Jambo", similar to
collie dog) or Nemo (the clownfish).
Pambo (1992 – )
Young male African elephant, who was a visitors' favorite. He was
transferred first to Vienna zoo, where he fathered an elephant girl
called Mongu, and was on October 26, 2009 transferred to Cabarceno
Natural Park in Spain. At his new home in Spain, Pambo lives
together with another bull and ten females.
Ruaha (1951 – 29.07.2010 )
Ruaha was the oldest known
African elephant at her time and the
matriarch of Basel's elephant herd. She came to
Basel on November 1,
1952 and was, while living, nine years older than North Americas
African elephant Dori at Hogle Zoo, Salt Lake City, Utah.
Ruaha was the matriarch of Basel's elephant group and was one of the
five original African elephants that came to
Basel into the new
elephant house. Similar to elderly humans, signs of her 59 years alive
were visible and she did not lay down to sleep for her last 20 years.
Nevertheless, her death came unexpectedly as she did not have any
health problems the days before her death. Ruaha was found dead in the
outdoor exhibit early morning on Thursday, July 29, 2010 by her zoo
Farasi (2008 – )
Farasi: September 2009
Farasi is a male hippopotamus that became world-famous when news broke
that zoo officials apparently intended to kill him and feed him to the
lions (or tigers, as per MSNBC).
Basel quickly denied these plans; however, the news of it spread
around the globe. His story was written in newspapers like the Wall
Street Journal and made it to TV news such as at MSNBC, that
claimed the zoo intends to feed Farasi to the tigers — even though
there are no tigers in Basel. He has a Facebook page in French.
On November 17, 2010, Farasi left
Basel to Tshukudu Private Game
Reserve in South Africa.
While Farasi has been "saved" from being Basel-lion food, ironically,
he was attacked by a lion in South Africa. As Farasi was at first too
small to defend himself against predators, he was kept in a large
enclosure on the reserve. However, in 2011, Farasi broke out of this
protected area and was eventually attacked by a lion during a night on
land. The wounds were not severe, but a veterinarian was called;
Farasi had to be tranquilized and was brought back to safety in an
enclosure with an electric fence. According to Sylvia Sussens, of the
reserve, Farasi should have been large enough to defend himself by
2012 and was scheduled to be released into the wild.
