Marwell Zoo near Winchester has opened an £8 million Tropical House – described as its “largest and most ambitious project”.
The new attraction is part of a 10-year, £17 million investment plan to create better animal habitats and guest experiences.
Marwell also claims to be the UK’s first zoo ‘powered by poo’, as animal waste will be converted into energy to heat the Tropical House and other buildings.
James Cretney, chief executive, said: “This exhibit is a key guest experience with complementary education and sustainability.
“It provides close animal viewing while setting new standards of husbandry for the species displayed.”
Under the Tropical House’s curved roof, a rainforest is home to animals such as a two-toed sloth, mouse deer and pygmy marmosets. There are also free-flying birds and more than 2,500 fish in the aquarium.
Upcoming events at the zoo include visits by botanist Dr Chris Anthemum and CBeebies’ Mr Bloom; plus ‘Boo at the Zoo’ during Halloween; and Christmas activities from November 17 to December 24.
