This is the main enclosure, an ancient grotto that has been at the zoo for decades. Apparently in the next couple of years there is the strong possibility that the lion and tiger grottoes will be renovated, although to be fair they are larger than most other pits that zoos keep their carnivores in.
Although these are not the best looking exhibits, they actually aren't bad at all for the tigers and lions who rotate between the three almost identical exhibits.
