The menagerie was photographed by John Edward Saché in 1860s.
The foundation of zoos in major cities around the world caused a growing thought among the British community in Kolkata that the menagerie should be upgraded to a formal zoological garden. Credence to such arguments was lent by an article in the now-defunct ''Calcutta Journal of Natural History'' July 1841 issue. In 1873, the Lieutenant-Governor
Sir Richard Temple formally proposed the formation of a zoo in Kolkata, and the Government finally allotted land for the zoo based on to the joint petition of the

Controversy
Pressed for space as Kolkata developed, and lacking adequate government funding, the zoo attracted a lot of controversy in the latter half of the 20th century due to cramped living conditions of the animals, lack of initiative at breeding rare species, and for cross-breeding experiments between species.
The zoo has also, in the past, attracted a lot of criticism for keeping single and unpaired specimens of rare species like the

The previously cramped, unsuitable and unhygienic conditions inside the cages, and in the zoo in general had been criticized for long. The death of a great Indian one-horned rhinoceros sparked off speculation about the veterinary efficiency at the zoo.

The zoo had also been criticized for the quality of its animal/visitor interaction. Teasing of animals was a common occurrence at the zoo, though corrective measures are now in place. On 1 January 1996 the tiger Shiva mauled two visitors as they tried to garland it, killing one, Shiva was later shot and killed by the Indian Army. Another mauling leading to a death occurred in 2000.

Layout
Laid out on of land, the Calcutta zoo has been unable to expand or modify its layout for over 50 years, and thus has a rather backdated plan. It contains a ''Reptile House'' (a new one has been built), a ''Primate House'', an Elephant House, and a Panther House which opens out onto the open air enclosures for the lions and tigers. It also boasts of a glass-walled enclosure for tigers, the first of its kind in India. A separate

The zoo is presently downsizing to meet animal comfort requirements laid down by the

Since the zoo is enveloped by urban settlements for miles, the zoo wetlands are the only resting spot for some of the birds and are a focus of conservationists in Kolkata. However, the number of migratory bird visiting the zoo dropped from documented highs by over 40% in the winter of 2004–2005. Experts attribute the causes of the decline to increased pollution, new construction of highrises in the area, increasing threats in the summer grounds of the birds and declining quality of the water bodies at the zoo.
