The Animal Hospital and Pathology Laboratory (occupied by the Institute of Zoology's Department of Veterinary Science) was built as a 'Sanatorium and Quarantine Station' to replace the sanatorium north east of the Bird House (see Prosectorium). The siting is deliberately remote from the Zoo's animal houses. On the ground floor there are offices, an operating theatre, an X-ray room, a food preparation area and animal dens around the west and south sides leading to outdoor cages in a walled yard. The first floor has offices, laboratories and large cages. Built 1955-56, Franz Stengelhofen, architect.
