He wanted to retain the birds of prey aviary and they were lowest on the priority list, I was sure that I wouldn’t change them, oh yes, sir, birds of prey aviary are wonderful. I want to conserve them as well. And then he wanted to have a special view and I said oh yes, that’s what we wanted to have too. So I haven’t had any difficulties. But I know that several zoos, for example Antwerp, have great difficulties with listed buildings. But there is one great example of the oldest zoo, still running zoo of the world. Tiergarten Schonbrunn in Vienna, who was found in 1752. The whole zoo is listed and my colleague and friend, Hermu Peklan, did wonderful work retaining the old buildings in the cages and in some, for example, in the carnivore house, he lets a visitor into the old cages and build large, new enclosures in front of the old cages.
