Whether the great curtain wall which divided the castle proper from the mere earthen enclosure be regarded as coëval with the outer wall, or of later date, the gateway in it, with the drum towers, of which a sketch and the foundations remain, were evidently later, and probably De Clare insertions.
The extinction of the De Clares, the division of the inheritance, the construction of Caerphilly, and the gradual pacification of the country, were causes which, with the long-continued misfortunes of the Despensers, no doubt led to the partial neglect of Cardiff, or at any rate, for a time, checked any additions to its buildings. Caerphilly, however, once so magnificent, seems to have been found too heavy a burthen, and to have been neglected, and the heiress who closed the line of Despenser was born at Cardiff. Probably this fact, and the ambitious designs of the Beauchamps, led to the partial reconstruction of the castle; which, moreover, had, no doubt, suffered from Owen Glendower. Richard and Isabel Beauchamp evidently built the great octagonal tower, bonding it securely into the old wall. Connected with this, and at the same time, they added, also outside of and bonded into the wall, the southern lesser wing, or that towards the town gate. Within the court they probably remodelled the lodgings, constructing a grand vault below the hall. Also, they added three turrets to the east wall, groining the interior of, at least, two of them as bays from the great hall, and embellishing with their armorial shield that which opened upon the dais. A tower, containing retiring-rooms at the south, and probably kitchens at the north end seem also to have been additions of the same epoch.
Within the court, upon the line of the eastern curtain, and up the slope of the mound, the Beauchamps also seem to have constructed or reconstructed the cluster of buildings of which a fragment only is left. This is that ruined tower which rises considerably above every other part of the enclosure, and adds as much to the picturesque appearance of the castle as it formerly did to its material strength.
The Herberts, in their day, made considerable changes. They seem to have pulled down the kitchens, or whatever buildings existed at the north end of the lodgings, and to have replaced them by an Elizabethan building with large mullioned bay windows. They also pulled down the buildings on the south, and established a kitchen garden on their site. It is probable that the Herbert work was of a much less solid character than that which preceded it, since it has all disappeared.
Towards the close of the last century, in 1778, soon after the Stuarts came into possession, under the advice of “Capability” Brown they pulled down the Herbert buildings, cleared the great court, filled up the moat of the keep (then called the Magazine), constructed the two wings, modernised the interior of the lodgings, and left everything, in general features, as lately seen.
It is singular, that in so important a castle as Cardiff no traces should remain of a regular gatehouse. Leland speaks of two gates, the Shire Hall and the Exchequer; of which the former was, no doubt, the present gate, and the latter, probably, that from the outer to the middle ward. That the present occupies the place of the original entrance is pretty certain. Where else could it have been? If cut through the earthworks, or through any other parts of the wall, traces would certainly remain. Probably, therefore, as already stated, and as was sometimes the case, the entrance was a mere gateway in the curtain; and the real barrier was that from the outer into the middle ward, which was certainly of great strength. The outer ward must have been a place of common resort for exchequer and other public business; and the knights’ lodgings were occupied regularly by some persons, though not usually by the owners. The traffic attendant upon this state of things would have made the formalities of gates, portcullis, and drawbridge, inconvenient, and may have been a reason for the usual regular defences of the gateway having been dispensed with. The foundations of these buildings, public and private, have been laid open in the great court.
The only remaining difficulty relates to the defences of the circumscribing embankment. Buck’s general view, published in 1748, and an engraving by Ryland, show an extensive wall, covering the great wall and the earthwork at the north-west angle, and prolonged upon the present course of the feeder. This can scarcely be one of Buck’s common errors in perspective, since he shows also the present wall capping the earthen bank. It is, therefore, possible that there was, on the north front, a wall between the bank and the moat. But, however this may be, it must be remembered that the enemy who surmounted the earthworks still had before him a fortress which for thickness and height of wall was equalled by few in Britain. The chapel of the castle, the Shire Hall, and the knights’ houses stood in the outer ward, and might be burned or destroyed; but the knights themselves, and their followers and effects, would take refuge and be in absolute security in the interior parts of the castle.
Rees Meyric, writing about 1578, has left a minute, and, on the whole, a very intelligible account of the castle as restored by the Earls of Pembroke for their occasional residence, before the building of Wilton. From his description it appears that the principal entrance was from the town by “a fair gate,” having the Black Tower with its prisons on the left, and opening into the outer ward. This ward occupied the eastern part of the general enclosure, being separated from the inner and middle wards by the mound and the strong curtain that extended from the Black to the White Tower or keep.
In this outer ward Leland saw the lodgings of the twelve knights of Glamorgan who held their lands by the tenure of castle-guard and the payment of ward silver. In Meyric’s time there remained but one, held by Sir Edward Mansell, and which had belonged to the Bassetts. Here also, near the north-eastern corner, as drawn by Speed and seen by Meyrick, stood the lord’s courthouse, used as the Shire Hall, and in which the lord’s court for the borough was held until late in the last century. This was protected by a special wall, upon which the knights’ lodgings stood and formed a part. A small chapel completed the group. This chapel was granted, with the parish church of St. Mary in Cardiff, by one of the early Norman earls to the monastery at Tewkesbury, and is mentioned in a general charter of confirmation by Nicholas, Bishop of Llandaff (“Dug. Mon.,” ii. 67). The space between the Shire Hall court and the adjacent bank was occupied by gardens and orchards.
The middle ward was entered a little north of the centre of the curtain wall, by a gateway between two drum towers, with a postern in that on the left.
