===Isca Dumnoniorum===
{{Main|Isca Dumnoniorum}}
The [[Latin]] name for Exeter is Isca Dumnoniorum ("Water of the Dumnonii"). This [[oppidum]] (a [[Latin]] term meaning an important town) on the banks of [[River Exe]] certainly existed prior to the foundation of the [[Roman Britain|Roman city]] in about AD 50. ''Isca'' is derived from the [[Brittonic languages|Brythonic]] word for flowing water, which was given to the River Exe. The Gaelic term for water is ''uisce/uisge''. This is reflected in the Welsh name for Exeter: ''Caerwysg'' meaning "fortified settlement on the river Uisc".

Isca Dumnoniorum originated with a settlement that developed around the [[Roman Empire|Roman]] fortress of the [[Legio II Augusta]] and is one of the four ''[[poleis]]'' (cities) attributed to the tribe by [[Ptolemy]].<ref name=RBOD>{{cite web

A legionary bath-house was built inside the fortress sometime between 55 and 60 and underwent renovation shortly afterwards (c. 60-65) but by c. 68 (perhaps even 66) the legion had transferred to a newer fortress at [[Gloucester]]. This saw the dismantling of the Isca fortress, and the site was then abandoned. Around AD 75, work on the ''civitas forum'' and ''basilica'' had commenced on the site of the former ''principia'' and by the late 2nd century the ''civitas'' walls had been completed. They were 3 metres thick and 6 metres high and enclosed exactly the same area as the earlier fortress. However, by the late 4th century the ''civitas'' was in decline.<ref>{{cite web
