But to return to the town. Its Old-English names, Tweonea and Twinham-burn, were given to it from its situation between the rivers Avon and Stour. They were afterwards corrupted into the Norman Thuinam; which was lost in the name of its Priory, overshadowing the town with its magnificence. Here, in 901, came Æthelwald the Ætheling, son of Æthered, in his rebellion against his cousin Edward the Elder, and seized the place. From Christchurch he fell back upon Wimborne, which he fortified, exclaiming he would do one of two things, “Either there live, or there lie.” That same night he fled to Northumberland.[159] From _Domesday_ we find that its manor was held in demesne by the Conqueror, as also by Edward the Confessor, with a mill renting for 5_s._, whilst another, belonging to the Church, was worth but 30_d._, and that thirty-one tenements in the borough paid a rent of 16_d._ Its woods, only, were inclosed in the Forest. The manor remained in the hands of the Crown till Henry I. bestowed it on his friend and kinsman Richard de Redvers, Earl of Devon, the ruins of whose castle still overlook the Avon. Here his son Baldwin de Redvers in vain fortified himself against Stephen. Here, too, lived his grandson William de Vernon, who helped to bear the canopy at Richard’s second coronation at Winchester. Afterwards, the manor passed into the hands of Isabella de Fortibus, who, on her death-bed, sold it, with all her possessions, to Edward I., who well knew the value of such a stronghold. Though Edward II. bestowed the estate on Sir William Montacute, yet the castle still remained in the hands of the Crown. It was standing, though no longer a fortification, in the Commonwealth period. Nothing, however, now remains but the mere shell of the keep, whose walls are in places four yards thick.[160] Below it stands what was, perhaps, the house of Baldwin de Redvers, also in ruins, and roofless, but still a capital specimen of what is so rarely seen, the true domestic architecture of the twelfth century. Like all the other remaining houses of this period, it is a simple oblong, seventy-one feet by twenty-four broad, and only two stories high, placed for defence on a branch of the Avon, which serves as a moat. On the south-east it is flanked by a small attached tower, now in ruins, under which the stream flows. The ground floor was divided in half by a wall, whilst the outer walls, thicker on the east and south sides, where more exposed to attacks than on the north and west, are pierced with deeply-splayed loopholes looking out on the stream. On this side was the hall, where lord, and guest, and serf, alike ate and drank, and slept on the floor. The other western half was divided into chambers and cellars, the kitchen probably standing in the courtyard. [Illustration: The Norman House.]
