Things to Do in Niš Serbia: Fortress, Skull Tower, Thermal Baths and More

Niš punches above its size for historical sights. The city’s Roman past, Ottoman legacy, and World War II history are each represented by well-preserved sites within a short radius of the city center. Here is what to prioritise across a two or three-day visit.

1. Walk Niš Fortress (Free)

The Niš Fortress (Tvrđava) sits on the Nišava riverbank and is free to enter at any time of day. Built by the Ottomans in the 18th century on older Roman and Byzantine foundations, the walls enclose a large park with a cultural center, open-air amphitheatre, restaurants, a craft brewery, and a mosque. Walk the inner ramparts for river views. Plan at least 1.5–2 hours if you want to stop for a meal or drink. Evening visits in summer bring live music from the amphitheatre.

2. Skull Tower - Ćele Kula (approx. €2)

One of the most unusual monuments in the Balkans and the most chilling sight in Niš. After the 1809 Battle of Čegar, Ottoman commander Hurshid Pasha ordered a tower built from the skulls of killed Serbian rebels. The original tower contained around 952 skulls; today 58 remain embedded in the structure, housed inside a neoclassical chapel for protection. Entry approximately €2 as of 2026. Allow 20–30 minutes. Located on Zoran Đinđić Boulevard, 15 minutes on foot from the fortress.

3. Red Cross Concentration Camp (approx. €3)

The only Nazi-era concentration camp preserved in its original form in Serbia. Between 1941 and 1944, the Gestapo held more than 30,000 people here, including Jews, Roma, and resistance fighters. The site includes original barracks, watchtowers, guard posts, and a detailed museum documenting the 1942 mass escape - the largest prisoner breakout from any German-operated camp in the Balkans. Entry approximately €3 as of 2026. Open Tuesday–Sunday 09:00–16:00. Around 2 km from the city center; a short taxi or 20-minute walk.

4. Mediana Roman Site (approx. €3)

Three kilometres east of the city center, Mediana was a 4th-century Roman imperial estate and one of Constantine the Great’s residences. Archaeological excavations since the 1930s have revealed mosaic floors, colonnaded corridors, storage pits, and a lapidarium with inscribed stones and sculptures. Entry approximately €3 as of 2026. Taxi from the center costs approximately €4–6; allow 1.5 hours on site.

5. Niška Banja Thermal Resort (day pass approx. €15)

Serbia’s oldest thermal spa resort sits 8 km east of Niš at the mouth of the Sićevo Gorge. The complex has six thermal pools fed by springs at 36–38°C, an outdoor pool for summer, and a village square with cafés. A day pass for pool access costs approximately €15 as of 2026. Bus line 25 from the city center runs every 20–30 minutes, journey time approximately 30 minutes, ticket approximately €0.70. Taxi approximately €5–8 one-way. Niška Banja also makes a quieter base for the area - several hotels here offer full-board packages with thermal access.

6. National Museum of Niš (approx. €2)

The museum on Nikole Pašića Square covers the city’s history from prehistoric times through the Roman period, medieval Serbia, Ottoman occupation, and into the 20th century. The Roman collection includes coins, ceramics, and sculpture from the Mediana excavations. Entry approximately €2 as of 2026. Open Tuesday–Sunday; closed Mondays. Allow 1 hour.

7. Čair Mosque

One of the few Ottoman mosques still standing in Niš. The Bali Beg Mosque in the Čair neighborhood dates to the early 16th century and is the oldest surviving Ottoman religious building in the city. Non-Muslim visitors may enter outside of prayer times. Free to visit.

8. Bubanj Memorial Park (Free)

A large park 3 km northeast of the city center, marking the site where German occupiers executed approximately 10,000 people during World War II. The central monument - three massive concrete fists - was designed by Ivan Sabolić in 1963 and remains one of the boldest pieces of Yugoslav-era memorial sculpture in Serbia. Free to visit at any time.

9. Nišava Riverside Walk (Free)

The Nišava riverside promenade runs through the city center, bordered by benches, cycle paths, and cafés. A morning walk from the fortress downstream to the Čair quarter and back takes under an hour. The promenade is liveliest on weekend evenings in summer.

10. Kayaking on the Nišava River (approx. €10–20)

Several local operators offer kayak and canoe hire on the Nišava River, mostly downstream from Niš toward the Sićevo Gorge. Sessions run approximately 2 hours; prices approximately €10–20 as of 2026 depending on operator and equipment. Enquire through the Niš tourist office on Vojvode Mišića Square or ask at your accommodation for current operators. You can also browse guided tours in Serbia for activity options in the wider Niš area.

11. Tvrđava Cultural Complex and Brewery

Inside the fortress walls, the Tvrđava cultural complex hosts film screenings, theatre, and music events from May to September. The Tvrđava Brewery adjacent to it serves craft beers brewed on-site; a half-litre costs approximately €2.50–3.50 as of 2026. Check the programme board at the fortress entrance for current events.

12. Day Trip to Sićevo Gorge

The Sićevo Gorge begins immediately east of Niška Banja and runs for approximately 20 km through limestone cliffs and dense oak forest. The Niš–Sofia railway passes through the gorge - one of the most dramatic rail routes in Serbia. For hiking, take a taxi or drive to the trailhead above Niška Banja; the ridge trail gives views into the canyon. No entry fee; allow a half-day.

Practical Notes

• The fortress, Skull Tower, Red Cross camp, and National Museum can all be done in one long day.
• Tuesday–Sunday is the safe window for most museums; many close Mondays.
• A two-day trip from Belgrade works well: overnight in Niš, day trip to Niška Banja or Sićevo Gorge.
• Bolt is available in Niš; most inter-sight journeys cost €3–6 as of 2026.
