MADRID — Zoos — or at least something resembling the traditional idea of a zoo — date back to ancient Mesopotamia. It was around 3,500 BC when Babylonian kings housed wild animals such as lions and birds of prey in beautiful structures known as the Hanging Gardens of Babylon.

Ancient China also played a significant role in the history of zoos when the Tang Dynasty (618-907 AD) created several parks which hosted an assortment of animals.

In Europe, it wouldn't be until 1664 when Louis XIV inaugurated the royal menagerie at Versailles. All these spaces shared the mission of showcasing the wealth and power of the ruler, or simply served as decorations. Furthermore, none of them were open to the general public; only a few fortunate individuals, usually the upper classes, had access.

The first modern zoo, conceived for educational purposes in Vienna, opened in 1765. Over time, the educational mission has become more prominent, as the exhibition of exotic animals has been complemented with scientific studies, conservation and the protection of threatened species.

For decades, zoos have been places of leisure, wonder, and discovery for both the young and the old. Despite their past success, in recent years, society's view of zoos has been changing due to increased awareness of animal welfare, shifting sensibilities and the possibility of learning about wild animals through screens. So, many people wonder: What is the purpose of a zoo in the 21st century?
