Carvetii

The Carvetii were a Celtic tribe and civitas of Roman Britain in the present-day counties of Cumbria and North Lancashire in North West England. They are mentioned in Ptolemy's Geographia neither nor in any other classical text, but are only of inscriptions in Penrith and Temple Sowerby in Cumbria known. It is believed that their capital Luguvalium, today Carlisle, has been. The assumption is based on the fact that Luguvalium is the only known town in the area, which had a city wall.
