The County Durham flag was registered on November 21st 2013. It was created by James Moffatt and his twin daughters Katie and Holly from Chilton, County Durham and was the winning entry in a competition established by noted adventurer and campaigner Andy Strangeway, in cooperation with the Durham County Council and the Flag Institute, to select a flag for the county, which had been the last shire in northern England, north of the Dee/Humber line, without one.
The winning flag depicts the Saint Cuthbert’s cross symbol, associated with the locality for centuries, countercharged in the blue and yellow colour scheme that has appeared in the arms and symbols of the various authorities and bodies that have administered County Durham through the ages, both as a palatinate territory of the Bishops of Durham and as a local authority area.
