It wouldn't surprise me at all to find that this used to house an elephant, as the zoo at one time had at least one Asian elephant and the building has been around for almost 60 years.
An excerpt from my 2010 review:
Kiey Building – A 1954 structure that is a mish-mash of a variety of exhibits. It is the indoor quarters for the Indian rhino, Nile hippo and Aldabra tortoises, but there is a section with about 10 different species of snakes (mainly a variety of small constrictors), a “swamp section” with only a foot-high barrier that has Blandings turtles and these birds: Javan munia, zebra finch, Cape thick-knee, golden-breasted starling and black-necked stilt.
The best part of the building is the nocturnal section, partially because my wife and I love nocturnal houses and also because here it is fairly well done in a single large room with exhibits along both sides of the room. There are 9 different species here: ring-tail, Eastern screech owl, sand cat, douroucouli (owl monkey), pygmy loris, greater galago and springhaas together, and sugar glider and Egyptian fruit bat in another mixed-species exhibit.
