The Sea Lion Pond, formed for sea lions and penguins, was London Zoo's first attempt at naturalistic, or Hagenbeckian, outdoor display and was based on similar structures in Paris and Cologne. Its design, in principle if not in detail, may be due to Sir Peter Chalmers Mitchell, the Zoo's principal exponent of this type of naturalism. Built 1905. Viewing stand, dens and kiosk added 1967, Franz Stengelhofen, architect. Kiosk awning added 1989-90. Pond remade 1992.
Demolished circa 2013 for Tiger Territory.
Formerly the zoo's Dolphin Pool, Seal Lion Splash is a daily demonstration in which the zoo's three trained Californian sea lions perform tricks and stunts in their pool (referred to as the 'Splash Zone').
