PENWORTHAM, Lancashire (Fig. 24).--"King Edward held Peneverdant. There are two carucates of land there, and they used to pay ten pence. Now there is a castle there, and there are two ploughs in the demesne, and six burghers, and three radmen, and eight villeins, and four cowherds. Amongst them all they have four ploughs. There is half a fishery there. There is wood and hawk's eyries, as in King Edward's time. It is worth £3."[565] The very great rise in value in this manor shows that some great change had taken place since the Norman Conquest. This change was the building of a castle. The _modo_ of Domesday always expresses a contrast with King Edward's time, and clearly tells us here that Penwortham Castle was new.[566] It lay in the extensive lands between the Ribble and the Mersey, which were part of the Conqueror's enfeoffment of Roger the Poitevin, third son of Earl Roger de Montgomeri.[567] Since Penwortham is mentioned as demesne, and no under-tenant is spoken of, we may perhaps assume that this castle, which was the head of a barony, was built by Roger himself. He did not hold it long, as he forfeited all his estates in 1102. At a later period, though we have not been able to trace when, the manor of Penwortham passed into the hands of the monks of Evesham, to whom the church had already been granted, at the end of the Conqueror's reign.[568] Probably it is because the castle thus passed into the hands of the church that it never developed into a stone castle, like Clitheroe. The seat of the barony was transferred elsewhere, and probably the timbers of the castle were used in the monastic buildings of Penwortham Priory. The excavations which were made here in 1856 proved conclusively that there were no stone foundations on the Castle Hill at Penwortham.[569] These excavations revealed the singular fact that the Norman had thrown up his motte on the site of a British or Romano-British hut, without even being aware of it, since the ruins of the hut were buried 5 feet deep and covered by a grass-grown surface, on which the Norman had laid a rude pavement of boulders before piling his motte.[570] Among the objects found in the excavations was a Norman prick spur, a conclusive proof of the Norman origin of the motte.[571] No remains appear to have been found of the Norman wooden keep; but this would be accounted for by the theory suggested above. Penwortham is a double motte, the artificial hill rising on the back of a natural hill, which has been isolated from its continuing ridge by an artificial ditch cut through it. The double hill rises out of a bailey court which is rudely square, but whose shape is determined by the ground, which forms a headland running out into the Ribble. The whole area cannot certainly be ascertained. There was a ferry at this point in Norman times.[572] The castle defends the mouth of the Ribble and overlooks the town of Preston.
