It looks good superficially but is apparently falling down! It was copied from those in some European Zoos, except they are usually made of solid rock whereas this is made of layers of concrete over a netting superstructure.
The other downside is in the viewing of this exhibit-the wall is fronted by flowerbeds/bushes so you can't look over it to see the baboons when they are down in the moated area. Overall though it has provided Paignton with a very good display over a long time. There are plans to completely replace it with another one nearby at some stage soon(?).
