44 Mediæval Military Architecture in England.

Castles, no doubt, there were at William's command, many and strong. All that is here contended for is, that whatever he may have desired, William was able to construct but few castles such as London or Durham ; and that the greater number of those that remain and exhibit the Norman style of architecture belong, some to the close of the eleventh, and a greater number to the twelfth century. But if William did not actually build so many castles as is supposed, he and his followers certainly restored and occupied an immense number, upon which those who came immediately after him built structures, the ruins of which we now see.
There is much to be learned from the consideration of the positions of these fortresses. William's first care, on obtaining possession of each district, was to order the preparation of such strong places as might be necessary for the holding of it. But it is evident that he was influenced also by another consideration : he desired to be regarded as the legitimate heir of the Confessor, rather than as the conqueror of the kingdom ; and so far as was consistent with his own security, he strove to administer the ancient laws, and to leave the ancient tenures and private estates, and even English owners, undisturbed. This indeed, owing to the strong national discontent, shown by repeated insurrections and by a general current of ill-will of which these were the indications, he speedily found to be out of the question. But even while driving out the native magnates, he was careful to associate the new men, as far as possible, with the past, in the hope (well founded) that before long the "successores et ante-cessores," as they are called in "Domesday," would be looked upon as part of a continued line,—Earl Roger, for example, as the representative of Edwin of Shrewsbury, Hugh Lupus of Morcar, and William Fitz Osbern of Ralph the Earl of Hereford under the Confessor.
And this policy is particularly evident in the sites of the castles. Where circumstances absolutely required it, an entirely new position was selected ; but this was extremely rare, and probably did not occur in half a dozen instances, if indeed in more than London and Richmond. Usually it was found that the English lord had attached to his estate an earthwork upon which he and his ancestors had lived for centuries, which was identified with the estate or district, and regarded with
