 In the west, there is a conurbation straddling the Hampshire/Surrey border, including in Surrey Camberley and Farnham.Before Roman times the area today known as Surrey was probably largely occupied by the Atrebates tribe, centred at Calleva Atrebatum (Silchester), in the modern county of Hampshire, but eastern parts of it may have been held by the Cantiaci, based largely in Kent.The Atrebates are known to have controlled the southern bank of the Thames from Roman texts describing the tribal relations between them and the powerful Catuvellauni on the north bank.
