Its ramparts run for about 2.1 kilometres around some 22 hectares, entered through the well-preserved Stambol Gate. Inside are the Bali-Bey Mosque, a hammam, an arsenal now used for art galleries, a lapidarium of Roman stone monuments and the remains of Roman-era buildings.
Today the fortress is the city’s green heart, with shady paths and cafés, and a lively summer venue that has hosted the Niš Film Festival since 1966 and the popular Nišville jazz festival.
