Glevum was established around AD 48, at an important crossing of the River Severn, and near to the Fosse Way, the early front line after the Roman invasion of Britain. Initially, a Roman fort was established at present-day Kingsholm in c. 65–70 AD.2
The Roman Legions based here were probably the Legio XX Valeria Victrix until 66 and then Legio II Augusta3 for their invasion of Roman Wales between 66 and 74 AD.4
Between AD 81 and 98, larger replacement walls were built on slightly higher ground nearby, centred on present-day Gloucester Cross which was probably part of the change from a military fort to a walled colonia after the Legio II Augusta had been transferred to Caerleon. The civilian settlement also grew outside the walls.5
In AD 97, the city was designated a colonia by the Emperor Nerva. A colonia was the residence of retired legionaries and enjoyed the highest status of city in the Empire. The legionaries were given farmland in the surrounding district, and could be called upon as a Roman auxiliary armed force.
The city was built within the legionary fortress and used the same rectilinear street plan and ramparts.6 A large and impressive administrative basilica and forum market-place were built in the town, as well as many fine homes with mosaic floors.
Roman Britain was divided into four provinces in the early 4th century. It is most likely that Glevum, as a colony, became the provincial capital of Britannia Secunda, in the same way that colonies at York and Lincoln became capitals of their respective provinces. There is some evidence that at this time Glevum possessed a mint.7
The Roman wharf where goods were shipped via an inlet from the River Severn has been excavated at Upper Quay Street and which dendrochronological dating has shown was built from 74 AD.8
At its height, Glevum may have had a population of as many as 10,000 people.
The entire area around Glevum was intensely Romanised in the second and third centuries, with a higher than normal distribution of villas, as a result of its suitability for the traditional intensive Roman farming methods. Today, some of the best examples of Roman villas in Britain, including Chedworth villa and Woodchester villa, both famous for their Roman mosaics, are not far from Glevum.
Excavations at Gloucester's New Market Hall in the 1960s910 showed that Romano-British occupation of the town may have continued in some form into the sub-Roman period, even if the town's population may have been greatly reduced. A new portal in the town's wall was built at the beginning of the sixth century, showing a modest growth of the town after the Battle of Mons Badonicus in 497.
The Anglo-Saxon Chronicle records a King Coinmail (according to the original A-text), who may have come from Gloucester, taking part in the Battle of Dyrham in 577, when the city was conquered by the Anglo-Saxons.
