Coat of arms of the London Borough of Camden: Argent, on a cross gules a mitre or on a chief sable three escallops argent. The red cross on a silver field is the Cross of St. George, which was present in the coat of arms of Holborn and represents the patron saint of two parish churches therein, namely St George the Martyr, Holborn and St George's, Bloomsbury. The gold mitre, like that in the coat of arms of Hampstead, refers to Westminster Abbey which held the manor of Hampstead for six centuries until 1539. The black chief with three silver escallops is from the  coat of arms of Holborn and escallops were also present in the arms of St. Pancras; the chief and escallops are ultimately derived from the arms of the Russell family, Dukes of Bedford, which holds a large estate in Bloomsbury, now much reduced in size.
