Halmyris: the Roman fort where the Danube meets the delta

Halmyris once stood at the very end of the Roman Danube frontier, and the Danube later left it behind: silt choked its harbour, and the river moved away from the walls.

The history of Halmyris

The area was already inhabited in the Second Iron Age by the Getae, or Dacians, as several cremation burials in a possible necropolis of the 4th–2nd centuries BC show. The settlement stood on a rocky peninsula on the bank of the Danube near the Black Sea, surrounded by marshes. In Roman times it lay at the most easterly point of the Danube frontier, the Moesian Limes, and probably served as a supply centre for the fleet. Over some 1,100 years, from the Iron Age to the Byzantine period, it was a depot for supplies, colonisation and cultural exchange.

The first Roman fort was built of timber and turf in the Flavian period. As it gained importance and a regular garrison was established along the Danube, it was rebuilt in stone under Trajan by detachments of two legions, the Legio I Italica and the Legio XI Claudia. An inscription mentions a village of mariners, a vicus classicorum, a name unique in the Roman Empire that confirms early links with the Roman fleet.

Early in its history the Goths crossed the Danube and took the fort, but the Romans won it back and rebuilt it with major changes in the Tetrarchy. The new walls formed an irregular polygon strengthened by 15 towers, with at least two well-defended gates, in the north and the west. Inside were barracks, a private bathhouse and a basilica. The north gate, which opened onto the Danube, was rebuilt in the 280s with two monumental U-shaped towers and finished in 301–305.

Christianity left a deep mark here. According to tradition the priest Epictetus and the monk Astion arrived in 273 and were martyred in 290 during the persecutions ordered by Diocletian. After 324, under Constantine I, an early Christian basilica was built in the centre, with a vaulted crypt whose walls were painted with plant motifs and carried a Greek inscription naming Astion. In the early 4th century the fort enjoyed a particularly prosperous period, becoming one of the 15 most important towns of Scythia Minor and a bishopric.

Decline came slowly. In the winter of 384/5 the Danube froze, letting tribes from the north cross and sack the town. Earthquakes in the 4th century and later damaged it, and the course of the Danube shifted, silting up the harbour and reducing the town’s economic and strategic importance. The last phase of occupation corresponds to a rebuilding under the emperor Justinian, and the fort was in use until the early 7th century before it was abandoned. Archaeological excavations began in 1981, and in 2000 the episcopal basilica was found; in 2001 remains bearing marks of extreme violence were identified in the crypt as those of the two martyrs. A Christian monastery now stands beside the ruins.

Visiting Halmyris: what to see

• The fort walls with their 15 towers and the main gates are the first things to look for; the west gate opened onto the Roman road that ran along the Danube linking the forts.
• Inside you can look for the baths with three pools, the crossing of the two main streets where the praetorium stood, and the barracks along the west wall, of which barracks no. 3 is the largest and best preserved.
• The early Christian basilica, with its crypt of the martyrs Epictetus and Astion, is the spiritual heart of the site; ask locally what can be visited.
• A monastery built to honour the two martyrs stands next to the ruins; the site is reached from Tulcea by the road to Murighiol and then by a gravel road, so allow time and expect a rural setting.
• The surrounding area at the mouth of the Danube is a landscape of marsh and water; Castrum Argamum is about 36 km away and Histria about 63 km. Check the current opening hours before you go.
