Marcianopolis, the Roman Provincial Capital at Devnya
Marcianopolis was a Roman city and provincial capital whose ruins lie at today’s Devnya, in north-eastern Bulgaria, about 25 km from Varna. It has been partly excavated, and visitors can see an amphitheatre, stretches of ancient street and rich mosaics, some still in place. It is an easy detour for anyone exploring the Black Sea hinterland.
For a few years in the 360s a Roman emperor ran a war from this town, once the largest city in Thrace. Today it lies under the modern town of Devnya, near Varna.
The history of Marcianopolis
The emperor Trajan founded the city after the Second Dacian War, which ended in 106, and named it after his sister, Ulpia Marciana. Roman inscriptions sometimes add his family name and call it Marcianopolis Ulpia. English Wikipedia says the site was earlier known as Parthenopolis, while German Wikipedia calls that identification mistaken, so the point is left open here. Roads from the Danube crossed here and led on to Constantinople and the Black Sea, which made it a key strategic centre. From 187 to 193 it was part of the province of Thrace, and afterwards of Moesia Inferior.
Under the Severan dynasty the city prospered. It was granted the right to mint its own coins under Commodus, and it struck them for decades. That prosperity ended with a Gothic raid in 248–249, when the defenders drove the attackers off, and with further invasions from the north. Later Gothic attacks, in the 260s, were also repulsed. Under Diocletian the city became the centre of the province of Moesia Secunda and was rebuilt thoroughly in the late third and early fourth century.
In the fourth century Marcianopolis grew in importance at the expense of its neighbour Odessos, today’s Varna. It was an important episcopal centre, and its bishop took part in the Council of Serdica, with a basilica from that period excavated in the twentieth century. During the war of Emperor Valens against the Goths in the late 360s, the city served as a temporary capital and winter residence of the empire, and an ancient source calls it the largest city of Thrace. The Notitia Dignitatum records an imperial arms factory here.
In 447 the Huns under Attila destroyed the city, immediately after the bloody battle of the Utus river. Justinian I restored and fortified it, and the historian Procopius reports repairs to the city wall in his reign. In 587 the Avars took Marcianopolis, but the Byzantines retook it at once, and in 596 the Byzantine army was quartered there before crossing the Danube to attack the Avars. An Avar raid in 614–615 finally destroyed the city, although it still appeared on maps much later.
When Slavs settled in the Balkans in the seventh century, they called the ruins Devina, the root of the modern name Devnya. Around 678 the region passed to the Bulgarians. Of the city’s Christian buildings, the remains of four churches are known, among them a presumed episcopal cathedral on a rise at the southern edge of the city, built as a single-nave church in the late fourth century and enlarged into a three-aisled one in the sixth.
