The Valley of the Tigers is composed of three distinct areas: the Siberian Tiger compound, the Sumatran Tiger compound, and at the center, the temple, a covered space, intended to inform and to raise the visitors’ awareness for these species.
 
The moment you climb the Valley of the Tigers steps, you notice eight large vertical tubes in acrylic, filled with Styrofoam balls. Each one represents a subspecies of tiger, and the level to which it is filled shows us how many animals of this subspecies exist in the wild.

It is impossible not to realize that three of the tubes are empty. This means that three of the subspecies are extinct: the Bali tiger, the Caspian Tiger, and the Java tiger. As for the two species present in the Zoo, it is estimated that, in their natural state, there are only 480 Siberian tigers and 400 Sumatran tigers left, the first being species considered "endangered" and the second one "critically endangered". 

In this space, we also learn that there are only around 6000 tigers left in the wild, including all subspecies, and we learn their characteristics, as well as their main threats.
