Limes Moesiae

Limes Moesiae was a Roman-built system of fortifications consisting of three lines of defense, between the Black Sea shore and the Danube. Additionally, in Wallachia there were other two lines of defense: the Constantine Wall and the Limes Transalutanus.

The Limes Moesiae, near the Danube delta, probably was built initially during Trajan times. Between the 2nd and the 3rd century was increased and abandoned.

It seems it was used by non-Roman kingdoms after the 5th/6th century and partially rebuilt and increased

It consists of three sections:

These three sections consist of earth ditchs, three meters high and two meters wide, and are very similar to the dykes between Roman Britain and Wales (like Wat's Dyke).

Near the Limes Moesiae there are two other limes related to the defense of Moesia (and Roman Dacia):

The historian Theodor Mommsen wrote that at the mouth of the Dniester river there was the old Greek city of Tyras, which was "annexed to the province of Moesia" by emperor Nero in 56 AD. There exists a series of its coins with heads of emperors from Domitian to Alexander Severus, showing that Romans were present in this area until the 4th century.

Mommsen even wrote that "Moldavia and the south half of Bessarabia as well as the whole of Wallachia were incorporated in the Roman Empire".

All these facts confirm the creation of defensive earth dykes in order to defend these new territories of the Roman Empire. Furthermore, Mommsen wrote, "Bessarabia is intersected by a double barrier-line which, running from the Pruth to the Dniester, ends at Tyra and appears to proceeds from the Romans".
