Mirebeau is the site of a monumentalcastrum or fortress for about 5000Roman legionaries. Extensive aerial reconnaissance and excavations since 1964 have shown the extent of the site and its presence ofLegio VIII Augusta. The large camp had stone ramparts with towers, gates,principia (headquarters) with monumental entrance, storehouses,thermae (thermal baths), anamphitheatre whose embankments are still visible, and a wharf on the riverBèze. The fort was surrounded by a V-shaped ditch, and later two more ditches were dug on two of the sides.[4]
Tile stamps of the VIIIth Legion show that the camp was built in 70 AD, when the legion arrived withVespasian in Gaul to oppose the revolts of theTreveri and especially theUbii andLingones against Rome. The legion left in 86 at the latest to its next base atArgentoratum (nowStrasbourg).
Civilcanabae built-up outside the fortress and continued after the army left at the crossroads of ancient roads on the site of the present village, becoming a substantial settlement. A theatre was restored by a Roman citizen's daughter when it was falling into ruin. Upstream an important Celtic and laterGallo-Roman sanctuary had developed.[5]
Other buildings around the fortress included amansio, a kind of hotel for state officials.
An underground aqueduct supplying the fortress has been excavated.
