Marius, The Giraffe Killed And Used For Lions, København Zoo, Copenhagen, Denmark

Starting in the early 1980s, Copenhagen Zoo has been undergoing a renovations aimed at replacing cages with enclosures which recreate animals' natural environments, giving a better lifestyle to the animals, and a more realistic experience to visitors. The Elephant House and 1.5-hectare (3.7-acre) Savanna are results of these efforts. The Savanna includes a Hippopotamus House where the hippos can be watched underwater.
The zoo has preserved many of its historical buildings. The oldest building still in use, a stable for yaks, was erected in 1872, and now houses the bactrian camels. A Herbivore House built in 1875 still houses herbivores, namely tapirs. An owl tower from 1885 is today left as a memorial commemorating how zoo animals were once kept.
