Ad medera
Haidra · حيدرة
A pair of towers marks Ad Medera on the Tabula, the sign of a proper town rather than a simple roadside halt, and the drawing fits, for this was a Roman colony, now Haidra in Tunisia. In the last years of Augustus the Third Legion was stationed nearby to guard the southern flank of Africa Proconsularis. After it moved on, veterans settled here under the Flavian emperors, and the town was laid out like an army camp, its two main streets running through four gates. Emperor Justinian later raised a mighty fortress, built almost entirely from older monuments, and much of it still stands.
