This little section with the bears and boars is certainly the worst in the zoo, despite being one of the newest.
Part of the newer (honestly!) 'Quaternary Park' section of the zoo, which features animals found in the region at the time the nearby Altamira cave art was created. Examples from the caves are present on the signage in this area to tie in with each species.
