In my many visits to Dudley in the past I was never aware of the Chimpanzees being kept there. A photo of the enclosure or the remains of it would be very interesting but I guess it would have to be long distance as its an unsafe area these days.
I remember a small enclosure at the top but it was always empty. Was only small and had a wire mesh front. If this was the chimp enclosure then I'm shocked, even with the standards of the 1930s!
