Sirmium

Sirmium, Serbia

The excavated Imperial Palace walls of Sirmium in Sremska Mitrovica glow in low sunset light beside a stone path.

Sirmium, now Sremska Mitrovica in Serbia, was once a Roman imperial capital, and its palace ruins sit among ordinary town streets.

The place

Sirmium lies under the modern town of Sremska Mitrovica, in the Vojvodina province of northern Serbia, on the bank of the Sava river. West of Belgrade, the flat farmland of Srem spreads around it, and the region still carries the ancient city's name: Syrmia, Srem or Srijem, depending on the language. The site is not a single walled enclosure with a gate. Roman Sirmium is woven into the present town instead, with palace foundations in the centre, excavated blocks wedged between flats and shops, and a protected archaeological zone that Serbia ranks as a Site of Exceptional Importance. The name itself is thought to mean flowing water or wetland, a fair description of a settlement on low ground beside a river. Historians disagree about how big the city became. A figure of around 100,000 inhabitants is often repeated, while one cautious estimate, based only on the extent of the dig, suggests far fewer. Grain imports across the Roman centuries could have fed several hundred thousand people, which hints at a busy place, though all of these numbers are uncertain. What can be said safely is that Sirmium was a working administrative and military city rather than a purely ceremonial one. Today it suits slow, curious travellers who enjoy archaeology mixed with everyday life: a coffee beside a wall that Roman builders laid, a short walk to the river, and a quiet town that sees few tour groups.

Its story

Sirmium's story begins well before Rome. Traces of organised life on the site go back to around 5,000 BCE, and by the 4th century BC the settlement was held by Illyrian and Celtic peoples, among them the Amantini and the Scordisci. Legend gave the city a founder, a king named Syrmus, but the name more likely comes from a word for flowing water, and the king was attached to it later. Rome took Sirmium around 14 BC, helped by Celtic allies. It became a colony in the 1st century AD and a staging post for campaigns, with emperors such as Trajan and Marcus Aurelius preparing expeditions here. In 103 the province of Pannonia was divided, and Sirmium governed the lower half. Its great moment came with the Tetrarchy in 293, when the empire was split into four parts and Sirmium was named one of the four capitals, alongside Trier, Milan and Nicomedia. It was the seat of the emperor Galerius. Three years later Diocletian redrew the Pannonian provinces, leaving Sirmium capital of Pannonia Secunda and of the wider Diocese of Pannonia. From 318 it also headed the prefecture of Illyricum, until 379, when its diocese was moved under Italy. Byzantine rule followed, and the ancient name survives in the region of Srem.

What to see

Culture

Sirmium's culture today belongs to Sremska Mitrovica and to Vojvodina, a province where Serbian, Hungarian, Slovak, Croatian and other communities have lived side by side for generations. Most locals are Serbian Orthodox, and church bells, family slava feasts and saints' days shape the calendar more than the Roman past does. Even so, the town is proud of its ancient identity, and the palace, the museum and several street names keep it visible. Social life runs on cafés. People linger over strong coffee, talk warmly and loudly, and treat a guest as someone to be fed. A glass of rakija, a fruit brandy, is a common welcome in homes, and refusing everything outright can seem cold. Football, river fishing and weekend market trips are everyday pastimes. Expect limited English away from the main square, though younger people often speak some, and a few words of Serbian, such as hvala for thanks, earn smiles. The Roman ruins are treated as a living part of the town, so they sit beside pavements, playgrounds and shops, and locals are usually happy to explain them to anyone who asks. When entering a home or an Orthodox church, take your cue from the hosts: leave your shoes at the door if others have, and keep shoulders and knees covered inside the church.

What to wear

Sirmium's Roman residents dressed in wool and linen tunics, with cloaks against the cold, and officials added the toga for ceremony; textiles rarely survive, so much is known from sculpture and mosaics. In the Srem countryside, traditional dress was made from homespun linen, hemp and wool, with white embroidered shirts, waistcoats, wide aprons and leather opanci shoes, while men wore the šajkača, a soft cap. Patterns differ from village to village. Today these outfits appear mainly at folk festivals, weddings, dance groups and church feast days. Everyday wear in Sremska Mitrovica is plain and European: jeans, trainers, light jackets, and neat shirts or dresses for evenings out. Visitors blend in easily with practical, modest clothes. In summer, bring a hat, sunscreen and breathable cotton, because the ruins offer little shade. Winters on the Pannonian plain are cold and damp, so layers and a waterproof coat help. Wear sturdy flat shoes, since excavated ground is uneven and paving can be slick after rain. For Orthodox churches, carry a scarf or light cover-up so shoulders and knees are covered; no special clothing is needed for the museum or the ruins.
