And geographically themed, which the Mappin Terraces never were. Presumably better built, given that the reason for taking goats & sheep off the London skyline was that the area was unsafe.
Hagenbeck's was of course the inspiration for the Mappin Terraces. It's a thousand pities the latter have not been developed in a more inspiring way.
Geographically themed? Not a chance. Back in the day it was in every exhibit a wild mix. Lions and tigers, all hoof stock in one exhibit, goats and ibex together and all waterfowl in the front.
Today it is a bit more african, but well:
In the front exhibit are chilean and kuban flamingos and waterfowl from all over the world. In the savannah exhibit are plains zebra, north african ostrich, warthog and (separated from the others) red river hogs). At the carnivore grottos are now subspecies-mix lions and (in the tiger cave) porcupine. The rock above the lions held formerly chained birds of prey, by now nothing on there anymore. In the back exhibits are now on the left barbary sheep and on the right himalayan tahr with red pandas
You should go!
The flamingos and waterfowl have a very large exhibit. The savanna for zebra and others is decent of size, also the warthog-exhibit. The lion exhibit is a bit small, but still not totally bad, porcupine is ok and barbary sheep is very good. Tahr and panda is outstanding.
