The north of the county is rich in archaeological evidence from the period, but nothing is known that suggests any Roman habitation in the Keswick area, other than finds that point to the existence of one or more Roman highways passing the vicinity of the present-day town.[13] Such nearby settlements as can be traced from the era of the Romans and the years after their departure seem to have been predominantly Celtic. Many local place names from the period, including that of the River Derwent, are Celtic, some closely related to Welsh equivalents.[n 2]
