WISBEACH, Cambridgeshire.--William I. built a castle here in 1072, after suppressing the revolt of Hereward, in order to hold in check the Cambridgeshire fen country.[781] There is an early mention of it in the Register of Thorney Abbey. This castle, after being several times rebuilt, is now completely destroyed, and "several rows of elegant houses built on the site." Nevertheless, there still remain distinct traces of the motte-and-bailey pattern in the gardens which now occupy the site of the original castle of King William; the present Crescent probably follows the line of the ditch. The meagre indications preserved in casual accounts confirm this. There was an inner castle of about 2 acres, just the area of the present garden enclosure, and an outer court, probably an addition, of some 4 acres.[782] Both areas were moated. Weston, a prisoner who was confined in the keep of this castle in the 17th century, has left an account of his captivity, in which he casually mentions that the keep or dungeon stood upon a high terrace, from which he could overlook the outer bailey, and was surrounded by a moat filled with water.[783] The castle is not mentioned in Domesday, but as might be expected in a district which had been so ravaged by war, the value of the manor had fallen. WORCESTER.--This borough, as we have seen, was fortified by Ethelfleda and her husband Ethelred in the 9th century. That the fortifications thus erected were those of a city and not of a castle is shown with sufficient clearness by the remarkable charter of this remarkable pair, in which they declare that they have built the _burh_ at Worcester to shelter all the people, and the churches, and the bishop.[784] The castle is first mentioned in the _Anglo-Saxon Chronicle_ in 1088, and it is to be noted that it is styled the king's castle. Urse d'Abitot, the Norman sheriff of Worcester, has the credit of having built the first castle, and Malmesbury relates that he seized part of the monks' cemetery for the bailey.[785] The monks, however, held on to their right, and in the first year of Henry III. the bailey was restored to them by the guardians of the young king, the motte being reserved for the king's use.[786] The first wooden castle was burnt in 1113.[787] The tower or keep which succeeded it, and which was repaired by Henry II.,[788] may have been either of stone or wood; but in the order of John, that the gateway of the castle, which is of wood, is to be made of stone, we get a hint of the gradual transformation of the castle from a wooden to a stone fortress.[789]
