From 41 B.C. milestones were erected in Braga by masons in the function of various Roman emperors, including Claudius, Nerva, Hadrian, Caracalla, Elagabalus, Maximinus Thrax, Carus, Carinus, Diocletian, Maximian, Galerius, Constantius Chlorus, Magnentius, Constantine and Maximinus Daia [REF].
The milestones were essential to the consolidation of the new territorial administration imposed by Rome and the routes served inherent military purposes, while assuring the transport of raw materials (specifically metals) essential to the good performance of the new imperial order [REF].
