The Michael Sobell Pavilions for Apes and Monkeys replaced a Monkey House of 1926 - the successor to several earlier buildings - as well as Decimus Burton's 1820s terrace which led from the main gate. First plans were drawn up by Franz Stengelhofen in 1966, but these were abandoned as costly and unsuitable. It was built 1970-72, benefaction from Sir Michael Sobell; brief by Dr M R Brambell, Curator of Mammals; John Toovey and Jonathan Myles, architects; Anthony Hunt Associates, engineers; Trollope and Colls (City) Limited, building contractors.
It was partly demolished and reopened with Gorilla Kingdom in 2007.
