Unknown enclosure

As you can see this is the end of the outdoor enclosure of the Chimpanzee\'s just past the end there are what look to be 2 indoor enclosures could be stable like.
The problem I have is according to all guide maps these are not there and yet when, I spoke to keepers they have said they were in use in the early days but could not remember what was kept inside any info please

Here are 2 more images if they help

Hi,
Many species have been held there over the years but I do believe it was origionally for camels. Other species to be held there are waterbuck, gazelles, Hyenas, Otters.....all these were only held here why there enclosures were being done up. Also, behind you there used to be the Sun Bear enclosure, this was partially under ground, I think it is filled in and is now used for rabbits. Hope this is some help.

Many thanks Nige did note the Sun Bear enclosure behind me had been filled in but was unsure about the species kept in the hidden enclosure,
