artificial mount on which the keep stands."[767] It is frequently mentioned in mediæval documents as the _beumont_ or _beau mont_. It was surrounded by its own ditch.[768] The bailey, if Speed's map is correct, was triangular in shape. With its ditches and banks the castle covered 6 acres, according to the commissioners who reported on it in Elizabeth's reign; but the inner area cannot have been more than 4-1/2 acres. We may infer from the sums spent on this castle by Henry II., that he was the first to give it walls and towers of stone; the _Pipe Rolls_ show entries to the amount of 1150_l._ during the course of his reign; the work of the walls is frequently specified, and stone is mentioned. Domesday Book does not inform us whether the value of Winchester had risen or fallen since the Conquest. [Illustration: FIG. 38. Windsor Castle (From Ashmole's "Order of the Garter.")] WINDSOR (Fig. 38).--Here we have another of the interesting cases in which the geld due from the tenant of a manor is lessened on account of a castle having occupied a portion of the land.[769] The Survey tells us that the castle of Windsor sits in half a hide belonging to the manor of Clewer, which had become William's property as part of the spoils of Harold. It was _now_ held of the king by a Norman tenant-in-chief, but whereas it was formerly rated as five hides it was now (that is, probably, since the castle was built) rated as four and a half hides. Of course we are not to suppose that the castle occupied the whole half hide, which might be some 60 acres; but it extinguished the liability of that portion. At Windsor, however, we have no occasion to press this argument as a proof that the castle was new, since it is well established that the palace of the Saxon kings was at least 2 miles from the present castle and town, in the village long known as Old Windsor, which fell into decay as the town of Windsor sprang up under the Norman castle.[770] The manor of Windsor was given by Edward the Confessor to the convent of Westminster, but recovered by the Conqueror.[771] But as the Survey shows us, he did not build his castle in the manor of Windsor, but in that of Clewer. He built it for a hunting-seat,[772] and it may have been for the purpose of recovering forest rights that he resumed possession of Old Windsor; but he placed his castle in the situation which he thought best for defence. For even a hunting-seat in Norman times was virtually a castle, as many other instances show.
