Sirmium
Roman Imperial Capital · Sremska Mitrovica, Serbia
Travel Tips & Guides
Sirmium was one of the four capital cities of the Roman Empire — alongside Rome, Nicomedia, and Trier — and the most important city in the Balkans for over 500 years. Today, the modern town of Sremska Mitrovica (pop.
~38,000) sits on top of the ancient ruins, a quiet backwater on the Sava River that bears almost no visible trace of its imperial past above ground. But below the soccer fields, bus station, and apartment blocks lies one of the most significant unexcavated Roman sites in Europe: a city that at its peak (3rd-4th c.
AD) covered 120 hectares with a population of 100,000+, complete with a hippodrome seating 30,000, an imperial palace complex, baths, and a mint that produced gold coinage for the entire empire. Only 4% of Sirmium has been archaeologically excavated; the rest waits under gardens, houses, and the town hall itself.
Spring (April-May) and autumn (September-October) when the Sava River is low and mosquitoes manageable. The annual 'Sirmium Days' festival in late September features Roman reenactments, gladiator shows, and discounted site entry. Avoid summer (35°C+) when flood risk is highest.
Srem specialties dominate: sremska kobasica (smoked paprika sausage), čvarci (pork cracklings), kulen (aged spreadable sausage). Restoran Carska Palata (€10-18) in the town center serves international and Balkan dishes. Čarda Panić (€8-14) specializes in Sava River fish — smuđ (pike-perch) breaded and fried, šaran (carp) in paprika sauce. Sirmium Restoran (€6-12) offers traditional Serbian grilled meats. Local wineries in surrounding Srem villages produce Frankovka and Bermet at 20-30% lower prices than Fruška Gora. The town's tap water comes from a Roman-era spring (Miloševac) still functioning today.
From Belgrade: Bus from BAS station every 30-60 min (1h45m, €7-10). Train from Belgrade Center Station (Prokop): 4-5 daily (2h-2h30m, €5-8). From Novi Sad: Bus (1h15m, €4-6) or train via Sremski Karlovci (2h, €4). Local: Sremska Mitrovica is walkable; local bus #1 connects the bus station to the center (50 RSD/€0.40). Taxi from center to the archaeological site is 2 km (~500 RSD/€4). By car: 60 km from Belgrade on the E-70 highway (45 min).
Hotel Sirmium (from €45) offers simple but clean rooms near the town center. Guesthouse Mitrovica (from €30) is a budget option. Most visitors visit Sirmium as a day trip from Belgrade or Novi Sad, but staying overnight allows you to explore the Zasavica Nature Reserve the next day.
