New building of the tiger´s enclosure, with the demand to simulate the local rocks, called "greywacke". An extensive, hand shaped artificial rocks construction made out of glass fibre reinforced concrete, was established. Also here the promenade was made of decorative stamp concrete. The artificial rocks formation was exactly suited to the present natural formation according to the orientation and addiction.

The used shotcrete has been applied onto a stainless steel grid base layer (animal consistent), molded and coloured.
