The Durham Historic Environment Record (HER) https://www.heritagegateway.org.uk/Gateway/Results_Single.aspx?uid=D8876&resourceID=109 says that this is "a stone milestone or property marker". But a longstanding local resident told me that the "C", which is the Latin letter for 100, indicated that the river (Wear) was 100 yards (presumably Roman yards) away. The location of this stone is shown in Image and Image
