The large-scale expansion of the Zoo will include Pannon Park, which will present the ancient flora and fauna of the Carpathian Basin on some 5 hectares. The central element of this will be the Biodome, designed by the Mérték Architecture Studio. The green area covering the exterior of the vast hall will make it resemble a grassy slope with vast glass surfaces, while its interior will attract visitors with its lush vegetation and diverse fauna. The building will be complemented by open-air runways as well as a state-of-the-art marine aquarium.
