The Thiruvananthapuram Zoo (also known as Trivandrum Zoo) is located in the city of Thiruvananthapuram, the capital of Kerala, India. It occupies 55 acres (22 ha) of woodland, lakes, and lawns. It is the oldest zoo in India and Asia.
Thiruvananthapuram Zoo is one of the oldest of its kind in India. Swathi Thirunal Rama Varma, who ruled Travancore between 1830 and 1847, established a menagerie where royal tigers, panthers, cheetahs, deer, boar, and other wild animals were kept. His brother Uthram Thirunal and British Resident William Cullen formally establish the zoo in 1857 as an annex to the Napier Museum. The zoo was originally built with the typical iron-barred cages prevalent at the time, and was designed for recreational purposes, but with increased loss of forest and wildlife due to human development, the goal of the Zoo has changed from recreation to conservation.
