Swathi Thirunal Rama Varma (1816–1846), the ruler of Travancore during 1830–1846, was the visionary behind the establishment of the Thiruvananthapuram Museum and Zoo.

In the Trivandrum, stables he incorporated a menagerie and kept tigers, panthers cheetahs, deer, bears and a lioness there.

It was however left to his brother Uthram Thirunal Marthanda Varma and the then British Resident General Cullen which resulted in the establishment of Napier Museum and Zoo in Thiruvananthapuram.

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.

The state government of Kerala is undertaking this renovation with financial and technical help from the Central Zoo Authority.
