Inside the fortress, there are buildings not run over by time from the Turkish period, such as the Bali-bey Mosque, arsenal, blacksmiths, hammam (now the Nišville Jazz Museum). 

Discovered too  are the remains of prehistoric, ancient, Byzantine, medieval periods, such as an Ancient street, Roman baths, lapidarium, palace with octagon, a bronze head of Constantine the Great, a statue of Jupiter, etc. Even today, the Niš Fortress lives as an inseparable tissue of the city center and the capital of festivals, knightly games, tourists, and good times.
