[3][4] It is also mentioned in the fourth- or fifth-century Notitia Dignitatum as Deruentione – the last auxiliary garrison "at the disposal of the Right Honourable Duke of the Britains".

[6] A further series of excavations between 1949 and 1952 by the Ministry of Works[7] in the civilian settlement uncovered multiple phases of activity as well as a road, several buildings and a mosaic.

A complex building sequence was revealed, with major phases occurring during the Trajanic, Severan, Constantian and Theodosian periods.

[3] The south and west defences of an early Roman military work were confirmed beneath the vicus buildings, very likely a southern annexe of the known fort.

Built on the north side of the River Derwent, this original phase was in timber, with the wall being rebuilt in stone in the early second century.

[6] The presence of the Ala shows that for at least part of its history, Derventio was capable of housing a mounted cavalry unit.

[8] To the west of the road a series of rectangular buildings of an average size of 25 by 40 ft stood closely compacted together and have been interpreted as workshops or store-houses; most of the pottery from this area, including much local ware, and coin evidence dates this area to the second half of the third and the first half of the fourth century.

The Dark Age settlement is the setting for much of the action in An East Wind Blowing by Australian author Mel Keegan.
