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

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.
Copenhagen Zoo Tower
A notable and highly visible feature of the zoo is the wooden observation tower. 43.5 metres (142.7 ft) high, it offers views of the surrounding parklands and city. The tower was built in 1905 and is one of the tallest observation towers built of wood in the world. Its base is similar to that of Eiffel Tower.
