Caldicot is mentioned in the Domesday Book of 1086, not for its castle, but as an agricultural holding of Durand of Gloucester, Sheriff of Gloucestershire. Walter FitzRoger, Durand's nephew, inherited his lands as well as his father's office of Constable of England which remained with the lords of Caldicot. Walter's son Milo was granted the Earldom of Hereford to add to his titles.[3] In the time of Henry I of England the castle was probably a simple motte-and-bailey.
