Following the reorganisation of northern Roman Britain and the construction of Hadrian's Wall (c. 122), the only Roman forts in Selgovae territory were at Birrens and Netherby. However, with the construction of the Antonine Wall and the re-occupation of territory north of Hadrian's Wall (c. 142), Selgovae territory was again heavily planted with Roman forts, at Netherby, Broomholm, Birrens, Burnswark, Raeburnfoot, Shieldhill, Milton, Drumlanrig, Dalswinton, Carzield, Lantonside, and Glenlochar. There were no Roman forts planted in the territory of the neighbouring Novantae.
