Limes Moesiae


The Moesian Limes or Limes Moesiae is the modern term given to a collection of Roman fortifications between the Black Sea shore and Pannonia, present-day Hungary, consisting primarily of forts along the Danube to protect the Roman provinces of Upper and Lower Moesia south of the river.
In addition the term Limes Moesiae may be used to include many other linked lines of defence were established in the region in different periods and later abandoned in favour of others depending on the military situation.

Characteristics

The Limes Moesiae includes essentially the linked forts and stations along the Danube from Singidunum to the mouth of the Danube on the Black Sea. It was not fortified with palisades or a boundary wall but the forts were linked by a road and included eight legionary fortresses, many forts for auxiliary troops and watch/signal towers. The legionary fortresses included:
Other forts included:
The frontier was divided into two major sections by the river Iskar at Oescus which also marked the border between the provinces of Moesia Superior and Inferior.
The narrowness of the river at Djerdap formed a barrier between north-west and north-east Moesia that was difficult to overcome, initially making communication between the Pannonian and the Moesian armies difficult. This problem was solved only by the construction of a 3m wide road under Trajan, who had the Legio VII Claudia chisel into the rock walls replacing a wooden towpath construction that was susceptible to damage by drift ice. Other improvements for shipping included the construction of a canal near Novi Sip to avoid the dangerous rapids and shoals there. The two ends of the canal were secured with forts. The best-known building on the Moesian Limes was Trajan's Bridge at Drobeta/ Turnu Severin from the early 2nd century AD, the first permanent bridge connection across the lower Danube which was also guarded on both banks by forts.
The Limes Moesiae may also include, depending on authors:
Many of these walls consisted of earth ditches, 3m high and 2m wide, and similar to the Antonine Wall.
The Limes was used by non-Roman kingdoms after the 5th/6th century and partially rebuilt and increased

History

During 29 and 28 BC shortly after the battle of Actium Marcus Licinius Crassus, proconsul of Macedonia and grandson of the triumvir, conquered the territory which was to become Moesia. Augustus formally proclaimed this event in 27 BC in Rome. Two legions were initially stationed in Moesia to counter threats from neighbouring Thrace and aggressive peoples north of the Danube. Auxiliary and smaller forts for vexillations of these legions were built along the Danube. At this stage forts on the frontier consisted of earth walls with wooden palisades. The wood and earth constructions were replaced by stone walls just before Domitian's Dacian War in 87 AD.
In the winter of 98/99 AD Trajan arrived on the Danube, quartered at the Diana fort near Kladovo, and started Dacian war preparations on the Iron Gates gorges. He extended the road in the gorge for 30 miles, as he stated on the well-known inscription of 100 AD. In 101 AD he also cut a canal nearby, as he also recorded on a marble plaque which reads:
“that because of the dangerous cataracts he diverted the river and made the whole Danube navigable”:.
Trajan restored stone defences in the area and rebuilt all earthworks in stone. Just below the Pontes fort a large port and massive horrea were built.
Between the first and second Dacian wars, from 103 to 105, the imperial architect Apollodorus of Damascus constructed Trajan's Bridge one of the greatest achievements in Roman architecture.
Full military occupation of the plain between the Carpathian foothills and the Danube may already have occurred
by the end of Trajan’s First Dacian War. The majority of forts here, however, were established after the final conquest of the Dacian kingdom in 106 AD. The abandonment of Moldova and the creation of the Limes Transalutanus can both be tentatively dated to the reign of Hadrian.
After a long period of peace Septimius Severus reconstructed the Moesia Superior defences and under Caracalla more reconstruction was done as can be seen at Pontes where, as with many other Iron Gates forts, the original layout was supplemented with the gates and towers. A new fort was built on an island at the Porečka river.
The Roman abandonment of Dacia probably occurred during the reign of Gallienus, before the traditional date of around 275 when Aurelian established the new province of Dacia south of the Danube.
In the Late Roman period, the extent of control and military occupation over territory north of the Danube remains controversial. One Roman fort, well beyond the Danubian Limes and near Moldavia, seems to have been occupied in the 4th century AD, as were bridge-head forts along the left bank of the river. In this Roman fort, built by Constantine I, researchers found a thermae building.
The "Brazda lui Novac de Nord" has been shown by recent excavations to date from emperor Constantine around 330 AD, at the same time as the "Devil's Dykes", a series of defensive earthen ramparts-and-ditches built by the Romans between Romania and the Pannonian plains.
Similarly, although considered 1st century and believed to predate the Limes Transalutanus, the function and
origins of a shorter section of bank and ditch known as the "Brazda lui Novac de Sud" remain uncertain. The absence of any evidence for Late Roman forts or settlements along its course and south of it rather suggests a later, probably medieval, date.
The fortification line erected by the king of the Thervings Athanaric, between the banks of river Gerasius and the Danube to the land of Taifali, probably reused the old Roman limes called Limes Transalutanus

Controversy

There is a controversy over the historical perspective of who built the earth dykes: the Romans, the Byzantines or others:
