Калемегдан
For decades, a long tunnel have been proposed in the western section of the neighborhood. It would actually follow the route of the Pariska Street, between the streets of Gračanička and Uzun Mirkova. This would allow for the ground level to be transformed into the plateau with a fountain, which would make an extension of the pedestrian zone of Knez Mihailova Street and create a continuous pedestrian zone from the Republic Square and Palace Albania to the Kalemegdan Park, the Belgrade Fortress and the rivers. It was envisioned by the first phase of the planned Belgrade Metro, 1973-1982.
