The remains of this bridge may yet be seen when the water is low, and the surface smooth. There seem to have been three piers of considerable size and solidity, set diagonally to the stream. The stones composing them are large, regularly squared, and fastened with metallic cramps.[84] Luis-holes, indicating the mode in which they have been lowered into their bed, appear in several of them. The firmness with which these foundation courses still retain the position assigned to them by the soldiers of Hadrian is very remarkable; the rolling floods of sixteen hundred winters seem to have spent their rage upon them almost in vain. As the eastern side of the river is frequently overflowed, the Vallum is here obliterated, but probably both works approached the bridge in close companionship. On the western side, appearances still bear out Horsley’s statement, that the 'Wall falls upon the middle of the fort, and Hadrian’s Vallum, as usual, falls in with the south side of it.' A plan of CILURNUM, and adjoining works, as figured by Warburton, is given in Plate II. Probably, few who examine it attentively will question the justness of the conclusion to which he has arrived, that the Wall, Vallum, stations, castles, and turrets, ‘by their mutual relation to one another, must have been one entire, united defence, or fortification.’ We are now arrived at the station called in the locality, Chesters, but by Horsley named, for the sake of distinction, Walwick-chesters. An attentive examination of it will well reward the antiquary. [Sidenote: CILURNUM.] CILURNUM.—This station has, as usual, the form of a parallelogram, the corners being slightly rounded off. It contains an area of fully six acres. In the latter part of the last century, when the mansion and estate of Chesters came into the possession of the family of Clayton, this area was covered with the ruins of buildings which had apparently stood in strait, narrow streets, and although the surface of the station has since been levelled and made smooth, in order to fit it for its use as part of the park, yet its ramparts and fosse, the Wall and Vallum as they approach and leave it, and the road leading to the river, may all be distinctly discerned; even the ruined dwellings of the interior area, as if dissatisfied with their lowly condition, struggle to rear themselves into notice. A portion of the Wall, near the north-west angle, has been freed from the encumbering soil; it is five feet thick, and exhibits four courses of masonry in excellent preservation.
