In a unique location, in the oldest part of Belgrade, in the cultural and historical part of Kalemegdan, along the Sava and the Danube, the former industrial zone will be replaced by a residential-business complex that will naturally be integrated into the old city core. At the same time, the new complex will be aligned with the urban life of modern Belgrade. The complex will be rich in trees and greenery, and a special quality will be given to its future promenade - a wide pedestrian zone that will leave an open view from Kalemegdan to the river, and with its decorated promenade connect the Belgrade Fortress with Beton Hall and the Danube. Kalemegdan and Port of Belgrade will get a new, natural clutch, by which the deserted ambient with the remains of the old railway will be transformed into a new, harmonious and well-preserved whole.
