[8] The park is situated in the estate of Marwell Hall, a Grade I listed building originally built around the year 1320 by Walter Woodlock[9] and largely rebuilt in 1816 by William Long.

[15] The publicity turned Marwell into a major tourist attraction, and interest was revived the following summer, when Victor's mate, Dribbles, gave birth to a female calf named Victoria.

In the late 1980s, a number of scimitar-horned oryx and nyala antelope were transported from Marwell Zoo to the Pearl Coast Zoological Gardens in Broome, Western Australia.

[18] There were other cases in the UK but Marwell was the only zoo to lose its entire colony, which had arrived only two and a half years before to stock the new Penguin World exhibit.

After consulting with experts, the exhibit was restocked with Humboldt penguins, which whilst endangered in the wild, are present in greater numbers in captivity.

Following a replacement after the death of Jade, in 2005 the first cub born to the new Amur leopard pair, Amirah, escaped into the male's enclosure and was killed by her father.

[19] On 18 November 2007, a female Amur leopard cub (named Kiska following a public vote) was born as a result of a European Conservation Breeding Programme.

The park includes a number of themed areas, including:The zoo's exhibits in 2022 included (in addition to those mentioned above in the Animal Exhibits section): In particular, Marwell houses a large collection of ungulates, including: Mammals in the zoo's collection include Amur tigers, Asian small-clawed otters, bearded emperor tamarins, binturongs, bush dogs, clouded leopards, common kusimanse, coppery titi monkeys, cotton-headed tamarins, crowned lemurs, golden lion tamarins, golden-headed lion tamarins, Linne's two-toed sloths, long-nosed potoroos, meerkats, narrow-striped mongoose, pygmy marmosets, red pandas, red ruffed lemurs, red-bellied lemurs, red-necked wallabies, ring-tailed lemurs, rock hyraxes, servals, siamangs, snow leopards, white-faced saki and yellow mongooses.
