Dinogetia: the Roman and Byzantine fortress at Garvăn
Dinogetia is an archaeological site at Garvăn, in Jijila commune, Tulcea County, Romania, a short distance east of Galați. It was a Geto-Dacian settlement, then a Roman fort on the Danube frontier and later a Byzantine stronghold, and its walls, basilica and baths make it a rewarding detour for anyone interested in the Lower Danube.
Dinogetia was a Roman frontier fort that burned, was abandoned for centuries and then came back to life as a Byzantine town. A bronze balance found here carries the name of a prefect of Constantinople.
The history of Dinogetia
Dinogetia began as a Geto-Dacian settlement that the Romans conquered and turned into a frontier fort, later mentioned by Ptolemy. It stood on a rocky spur in the curve of the Danube, in the Roman province of Moesia, and formed part of the Moesian Limes, the defensive line along the Lower Danube. Pottery fragments and coins of the 1st to 3rd centuries point to an earlier Roman fort, but its exact place has not been found.
The fort known today was largely rebuilt in the time of Diocletian, who reigned from 284 to 305. The walls are about 3 metres thick and were strengthened with horseshoe-shaped towers, and the enclosure covers about 7,800 square metres. Stamped bricks show the presence of the Legio I Iovia, and the Notitia Dignitatum, a late Roman list of military posts, mentions the Milites Scythici here. In the 4th century buildings were added inside, among them a supposed praetorium, a basilica and the house of an aristocrat, while baths stood just outside the walls. Written sources also record Christian martyrs from the army under Licinius, a sign that Christianity had reached the area.
Under the emperors Anastasius and Justinian the walls and buildings were repaired. In 559 the Kutrigurs under Zabergan overran the region, and Dinogetia suffered badly, although it recovered. Layers of burning and coins dated to 591–592 show a last catastrophe, which is linked to the Avar raids of 596 and 597. The fort was then abandoned for roughly three and a half centuries, and the Danube frontier of the Eastern Roman Empire collapsed under pressure from Slavic tribes.
After the campaigns of Emperor John I Tzimiskes, who won in 971, the Byzantines returned to the Lower Danube. The old walls were repaired and the site became a garrison and then a settlement, reaching its height in the 11th century, when houses were built inside the fort. A small domed church with a semicircular apse was built within the walls, one of the oldest stone churches in present-day Romania. Raids by nomadic peoples in the 11th century damaged the lower town, and residents buried coins and jewellery that they never recovered. The town was gradually deserted in the 12th century. Excavations began in 1939 under Gheorghe Ștefan and resumed in 1949, later led by Ion Barnea.
Curiosities about Dinogetia
- A bronze balance found here carries the name of Flavios Gerontios, a prefect of Constantinople in Justinian’s time, so it was probably checked in the capital and sent here.
- A Byzantine double cross made of two flat metal crosses fixed together was among the Christian finds.
- Two bone flutes from the 10th to 12th centuries were uncovered during the excavations.
- Two medieval hoards of Byzantine coins were found here, in 1939 and 1954. One of them had been buried in a pottery pot in 1073–1074.
- A late Roman baths building outside the walls measured about 25 by 18.5 metres and stayed in use until the early Byzantine period.
- The small church inside the fort is counted among the oldest stone churches in present-day Romania.
