See - I rather like this. Naturalistic inside the enclosure, so the animal is shown in context (for education reasons) and can behave naturally (for welfare reasons). Outside the exhibit, it's a proper zoo building. Quite an old and interesting one, by the looks of the design. No fake rockwork walls or anything, just a solid building. Very nice. Of course, a clever place will mix this style of exhibit with more all-out naturalistic ones to produce a diverse display. Only thing I would say; its hard to judge scale just from the photo, but looks like it might be just a bit on the small side for Gilas?
