Decimus Burton’s Giraffe House
Decimus Burton, the zoo’s first official architect, laid out its grounds in 1828 and completed the Giraffe House in 1837. It is still in use and is listed at Grade II.
The Penguin Pool
Berthold Lubetkin and the Tecton group designed the Penguin Pool and the Gorilla House in the 1930s; both are listed at Grade I. Today the zoo’s penguins can be seen at Penguin Beach, which opened in 2011.
From aviary to Monkey Valley
Hugh Casson’s pavilion for elephants and rhinos and the Snowdon Aviary were built in the 1960s. The aviary’s frame of steel masts and mesh now encloses Monkey Valley, which opened in August 2022.
