What is the actual 'House' made of do you think? Concrete/brick or is the outer 'shell' metal/prefab type, like a lot of modern 'economy' zoo houses nowadays, enclosing the inner enclosure?
I just saw the 3rd series of 'The Zoo' and it features lots of footage and information about the new gorilla enclosure, highly reccommended for anyone interested in this enclosure or Dublin Zoo in general.
