Several Roman camps lie near Birrens, at least one first occupied in the Flavian period from AD 79, probably during the Agricolan campaigns, when its internal buildings would have been timber.

Birrens Roman Fort is a fortified place near Middlebie, Dumfries and Galloway, Scotland.

What follows is drawn from published sources, with each claim labelled by how firmly it is established.

The name

The Roman name Blatobulgium is recorded in the Antonine Itinerary. It derives from the Brittonic *blāto- ('bloom, blossom', or from earlier *mlāto-, 'flour') and *bolgo- ('bag, bulge'), so may mean 'flowery hillock' or 'flowery hollow'. Because the fort had granaries, it has also been suggested the name was a nickname meaning 'Flour Sacks'.

History

Several Roman camps lie near Birrens, at least one first occupied in the Flavian period from AD 79, probably during the Agricolan campaigns, when its internal buildings would have been timber.

Under Hadrian, soon after AD 122, a new fort was built as an outpost of Hadrian's Wall on the site of a late-1st-century fortlet, with timber buildings and a large western annexe.

The visible fort dates from the Antonine period around AD 142, when, after the reconquest of the Scottish Lowlands, it was rebuilt and enlarged to protect the western road to the Antonine Wall and to hold a nominally 1,000-strong milliaria equitata garrison, the 1st Cohort Nerviana Germanorum.

It was destroyed, perhaps by enemy action, around AD 155. The poorer-quality stone buildings of the second Antonine period (from AD 159) housed a new garrison, the 2nd Cohort of Tungrians, also milliaria equitata. From about AD 163 it was again an outpost of Hadrian's Wall, and was finally abandoned by about AD 184.

Cultural influences

Part of the Roman outpost-fort system beyond the frontier — Birrens guarded the main western road into Scotland and, when the frontier lay on Hadrian's Wall, served as an outpost about 11 miles from the Castra Exploratorum fort (Netherby, Cumbria).
It formed the northern terminus of the Roman-era Watling Street (in its extended definition), or Route 2 of the Antonine Itinerary, and lay in the territory of the Selgovae.
