Chimpanzee exhibit at Lübeck (now closed)in 2008. To show that it was certainly not the worst zoo as said under other pictures.
This was an old house for small monkeys and birds. A circus left the three chimps (2,1) at the zoo and they tried to keep them as good as possible. And no other zoo would take them. These outdoor cages were built later for this house and it was supposed to get even bigger. In the left cage were 1,1 and in the right 1,0 (who was hand raised and could not get along with the others).
