Unveiling London Zoo’s Hidden History and Surprising Secrets

London Zoo, established in 1828 in Regent’s Park by the Zoological Society of London (ZSL), was the UK’s pioneering scientific zoo. Today, it operates as a vital conservation charity. The zoo holds numerous lesser-known historical facts and unique features. For instance, the Casson Pavilion, once the elephant house, conceals a secret basement used by keepers, a fascinating time capsule of vintage zoo adverts.

Its historical influence extends to language and culture. The zoo’s penguins inspired the iconic logo for Penguin Books, with an employee sketching them at the now-listed art deco pool. Furthermore, the name “Jumbo” for large objects originated from Jumbo the elephant, a famous resident. The term “aquarium” also came from the zoo’s world-first “aquatic vivarium.” During World War I, London Zoo’s sea lions were trained for submarine detection, though hydrophone technology ultimately rendered them unnecessary. The East Tunnel, now a public passage, served as a bomb shelter for staff and locals during World War II, displaying historical posters.

The zoo also boasts a history of innovation in animal care and public engagement. Its 1921 aquarium, housed under the Mappin Terraces, initially received saltwater from the Bay of Biscay via Regent’s Canal barges, highlighting early efforts to replicate natural habitats. Beyond its animal exhibits, London Zoo hosted the world’s first dog show in the 1840s, showcasing various breeds, followed by the first poultry show. Perhaps most significantly, a visit by Charles Darwin in 1838 to observe Jenny the orangutan profoundly influenced his Theory of Evolution, demonstrating the zoo’s foundational role in scientific discovery.
