The most important development of the Budapest Zoo took place between 1909 and 1912. Most of the characteristic buildings were set up during this period in the area according to the plans of Károly Kós and Dezs? Zrumeczky, two prominent architects of the Hungarian art nouveau. The Zoo suffered a lot of change from alterations and wars in the 20th century, its rehabilitation began after 1989, and was led by the office of Australian architect Anthony Gall who had been working in Hungary since then. (The studio of Péter Kis also joined in on the task.) The aim was to bring back the atmosphere of the monarchic times. The tasks fell in three types: renovation (palm house, elephant house, great rock), rebuilding, and erecting entirely new buildings. The exotic, African-style crocodile house was built up by 1912 for instance, but it was demolished after twenty-four years. It was rebuilt for its original purpose in its original shape according to the plans of Sándor Czégány by 2006. The new savanna yard designed by Anthony Gall was finished in 2008, and was inspired by some of the original buildings. The yard for the giraffes is really unique with its five meters high gates. The dome of the central clearing was set up by carpenters from the Transylvanian village of Gyergyószentmiklós, and was delivered to Budapest in pieces. This part of the structure was a tribute to Károly Kós who spent most of his life in Transylvania and showed a preference for using the motives of his motherland on his buildings erected in Budapest.
