The indoor exhibit for lowland gorillas inside the Gorilla House in Artis Amsterdam. The gorillas share this exhibit with white-throated guenons and slender-tailed meerkats. Quite a nice exhibit actually: decent-sized, light, some climbing structures, soft wood-ship substrate (good for foraging) and some live plants.
My only suggestion for an easy improvement would be to span a net over the exhibit making it possible to have more extensive climbing frames (which especially the guenons would benefit from).
