Zoo mound

Hungary-based architecture firm Atelier Peter Kis is renovating 'the great rock'at the Budapest zoo, an artificial land mass designed to mimic the natural habitats of the animals on display. originally built in 1909, the 40 m high hills feature an internal space of 38,850 m3. the design includes the reworking of this cave-like area in to an exhibition space for cultural programs, events and conferences.
