Alice, the daughter and heiress of Henry de Lacy, married Thomas, Earl of Lancaster, and, in her right, of Lincoln, grandson of Henry III., and thus both the constableship and the fee of the castle became absorbed in the Duchy of Lancaster, and so in the Crown. During the wars of Charles and the Parliament, the castle was held as a military post for the king. In 1644 it fell, with the city, into the hands of the Parliament, and finally, in 1832, was sold to the county. The Pipe and Close Rolls contain many entries in the reigns of Henry II., Richard I., John, and Henry III., relating to the castle, sometimes for repairs, sometimes for manacles for prisoners, sometimes for sustentation of soldiers. There are orders for storing corn, for “balistæ ad strumum” and “ad turnum,” the former worked by hand, the latter by a winch. In 1225, we read of repairs to the gate of the castle, to the “Tour de Luce,” and to the barbican. Even in Domesday, we have Waldin, ingeniator; Heppo, balistarius; and Ody, arbalistarius. THE TOWER OF LLANQUIAN, GLAMORGAN. About two miles east of Cowbridge, and half a mile or so north of the old Roman way from that town to Cardiff, a brooklet from St. Hilary Down crosses the road, and descends a deep and narrow ravine, to fall into the broad Aberthin valley, about two miles above its junction with the Cowbridge Taw, near the village of Aberthin. The ground on either bank of the ravine is very strong, and has been occupied for the purposes of defence from an early period. On the right bank is a large and irregular, and, therefore, probably British, enclosure or encampment; the defences of which, on the upper or eastern side, are two banks, each with an exterior ditch; and on the lower, or northern and western sides, a single bank, the ground below being sufficiently steep to render a ditch impracticable and unnecessary. This camp is locally known as _Erw Gron_, or the round acre (unless otherwise described, the acre would probably be a rectangular slip). On the left or western bank, nearly opposite to the camp, is a rocky knoll, a little raised above the ground immediately adjacent to the west and south, but which towards the east and north slopes rapidly towards the brook and the Aberthin valley, perhaps a hundred feet below. Beyond the depression on the west and south, the ground expands into a platform of moderately level but broken ground, beyond which again is a considerable rise. Thus the knoll is both secluded from observation, and naturally strong, at least on the northern and eastern sides, and very defensible on the others. The approach was from the south-west, from the Cowbridge road, in which direction are buildings and remains of buildings, part modern, but part evidently having belonged to the outworks and outbuildings of the Tower.
