Gloucester (i) is a city, district and county town of Gloucestershire in the South West region of England. Gloucester lies close to the Welsh border, and on the River Severn, approximately 32 miles (51 km) north-east of Bristol, and 45 miles (72 km) south-southwest of Birmingham.
A cathedral city, capital of its county which was built on a flat spot of land, Gloucester is situated on the River Severn and the Bristol and Birmingham Railway.
Gloucester was founded in AD 97 by the Romans under Emperor Nerva as Colonia Glevum Nervensis, and was granted its first charter in 1155 by King Henry II. Economically, the city is dominated by the service industries, and has a strong financial and business sector, being home to the bank Cheltenham & Gloucester and historically was prominent in the aerospace industry.
The origins of the name Gloucester can be traced to Caerloyw in the modern Welsh. There are various appellations in history such as Caer Glow, Gleawecastre, Gleucestre as an early British settlement is not confirmed by direct evidence. However, Gloucester was the Roman municipality of Colonia Nervia Glevensium, or Glevum, built in the reign of Nerva. Parts of the walls can be traced, and a number of remains and coins have been found, though inscriptions are scarce. In Historia Brittonum, a fabled account of the early rulers of Britain, Vortigern's grandfather, Gloiu (or Gloyw Wallt Hir: "Gloiu Long-hair"), is given as the founder of Gloucester. In the Anglo-Saxon Chronicle, Gloucester is shown as part of Wessex from the Battle of Deorham in 577 until 584, when it came under the control of Mercia. The name Gloucester derives from the Anglo-Saxon for fort (Old English ceaster) preceded by the Roman stem Glev- (pronounced glaiw).Claudia Castra is mentioned in the 18th Century as possible Latin name related to the city..
