Belgrade fortress is the place from which modern Belgrade emerged and developed. The Fortress is the ultimate symbol of the city and a place that "tells stories about a different Belgrade". Various cultures have intertwined in this historical landmark over the centuries. The oldest preserved remains of the fortress date back to the 1st century AD, from the times of Roman Singidunum. Today, most of the Belgrade Fortress complex is open to visitors. It consists of the Upper and Lower towns, as well as Kalemegdan Park.
