| Period I | before AD 70 | Native occupation at Brough House. |
| Period IIa | c.AD 70 | First Roman occupation: a temporary camp of unknown size. |
| Period IIb | c.AD 70-80 | Permanent auxiliary fort replaces temporary camp, supervising store-depot which probably lies to the south. The fort was evacuated c.AD 80. |
| Period III | c.AD 80-125 | The store-depot is maintained although the fort is no longer occupied. |
| Period IV | c.AD 125 | A brief reoccupation of the fort: the defences are refurbished and some internal buildings are constructed. |
| Period V | c.AD 125-200 | The gradual development of the vicus. This is a slow process until the later Hadrianic or early Antonine period. The settlement is surrounded by bank and a ditch. The theatre may have been built at this time. The site may still be acting as a supply depot or a base for a naval detachment, as well as acting as a civilian centre, possibly the civitas capital of the Parisi. |
| Period VI | c.AD 200-70 | The second phase of turf and timber fortification, on a different line from the first, with much internal building construction. These fortifications are more similar to military defences than to other contemporary urban defences. |
| Period VII | c.AD 270-90 | The fortifications are converted to stone in a series of stages. The work may have been interrupted. |
| Period VIII | c.AD 290-370? | Work is resumed on the defences, adding bastions and gate-towers and rebuilding some Period VII defences. |
| Period IX | c.AD 370 | Latest period of occupation at site. The ceramic evidence suggests a shrinkage of occupation towards the south-west corner of the town. The latest coin dates to Magnus Maximus. |
