Mediæval Military Architecture in England, Volume 2 (of 2)

by George Thomas Clark

The platform, to which the keep forms the key of the approach, is in plan a rhomboid, in length from north to south 600 yards, and from east to west 300 yards, covering about 19 acres, and its table summit ranges from 300 feet to 336 feet above the sea level. The two eastern or seaward faces, measuring together about 700 yards in length, rise abruptly from the sea beach, and are absolutely impregnable. The north-western face, 300 yards in length, and looking towards the north bay and sands, is lower, but still precipitous. The south-western face, also 300 yards in length, looks towards the town. Though not precipitous it is very steep, and at its base a broad ravine, known as the castle moat, intervenes between the castle and the town. A chapel and a burial-ground formerly occupied the seaward salient of the cliff, and behind these was Our Lady’s Well, the spring supplying which was reputed inexhaustible. The lowest and the only weak point in the platform was the landward or western angle, and here was posted the keep, from which northwards and southwards along the crest of the contiguous faces a curtain-wall was extended. Northwards, this wall was in length about 70 yards, ceasing as the cliff rose in height, and rendering artificial defence unnecessary. Southwards, the wall, from 20 feet to 25 feet in height, was carried all along the south-western front, and was strengthened, either originally or at an early period, by ten or twelve half-round turrets of various sizes. The six smaller were solid, like those of Coningsborough and Knaresborough; the larger, from 25 feet to 30 feet diameter, were hollow. These towers were parts of circles in plan, and have been much mutilated. They were probably cut down and filled with earth during the siege of 1640, when a swivel-gun seems to have been mounted en barbette on each. At present they are open at the gorge, and no higher than the contiguous curtain. Three loops may still be traced at their basement level, and two or three others at what must have been the first floor. Outside the wall are a number of buttresses of various sizes, shapes, and dates, some of which seem original, and of the late Norman period. The largest of these bastion towers is known as “The Queen’s Tower.” Near the centre of this front, upon the curtain, was a building about 110 feet by 40 feet, called “Mossdale,” or “The King’s Hall.” No doubt here stood the hall, kitchen, and other offices for the accommodation of the garrison. The present building is a modern barrack, built with the usual disregard of taste that has long characterised such buildings.

Where the curtain of the south-eastern front terminates on the sea cliff there seems anciently to have been a tower, known as “Cockbill.” More recently a small battery has been constructed outside the wall, and upon the crest of the slope, raking the ditch, and commanding a part of the harbour. Probably this battery was thrown up in preparation for the Parliamentary siege, for the remains of the tower above it are known as “Charles’s Tower.” Although the southern curtain has been much mutilated and restored, and towers, bastions and buttresses incorporated with its substance, the greater part of it is old, and probably original.

PLAN OF SCARBOROUGH CASTLE.

For the protection of the keep, quite as much from the mercenaries who, in the twelfth century, often formed the garrison, as from the exterior foe, an oblong space 112 yards north and south by 573 yards east and west, was walled in as a base court or bailey. It is taken out of the platform, and includes the keep. Its outer or western wall is the outer wall of the place, its opposite or eastern wall shuts out the keep from the main platform, and at the exterior foot of this wall, and within the platform, is a deep ditch. If the keep be regarded as the centre of the fortress, this enclosure is the inner ward, but as regards the position of the main entrance the platform deserves that name. It will, on the whole, be convenient to reserve the name of platform for the large area, and refer to the other as the bailey. Probably the bailey originally contained the Lords’ Hall, or kitchen, chapel, and lodgings. All traces of these have, however, disappeared above the surface. The position of the well is marked by a depression in the sward. The entrance to the castle occupied a hollow way below, and to the west and north of the keep traversed the bailey close below the keep, and entered the platform at the point now occupied by the modern guard-room. The approach to the castle must always have been settled by the peculiar character of the ground. There is, in fact, but one practicable line, that along the ridge between the edge of the cliff overlooking the north bay and the head of the ditch between the castle and the town. This ridge has been fortified on one side, where the cliff is about 240 feet high, by a light parapet wall, and on the other by a much stronger wall, which branches off from the curtain of the bailey, and commands the head of the ditch. Where they commence the two walls are about 50 yards apart, but they rapidly converge, and at 70 yards from the keep are but 12 feet apart, and thus continue, forming a raised causeway, along which the approach is carried. This causeway traverses the depression of the ground at the head of the castle moat by a sort of viaduct, which at its deepest point is about 25 feet high, and is in length, from its entrance in front of the keep to its termination in the barbican, about 70 yards. It is of masonry with lateral parapets, and a roadway 10 feet 6 inches broad. Near its centre is a strong pier, or rather a tower, about 32 feet broad, angular below the roadway and rounded above. This tower is pierced by a passage, and is, in fact, a gate-house, having for its defence a battlemented floor above the gateway, which was reached by a narrow staircase contained in one of the piers. The corbels on which the battlements rested remain. From this tower there seem to have dropped two drawbridges, one each way. That falling outward covered a pit 15 feet broad, now vaulted over as a permanent bridge. Its place is marked by an arch in the causeway, there about 20 feet high. The spandrel walls and parapets seem original, and the bridge worked between them, as was not uncommon, and may be seen at Goderich, and at the constable’s gate at Dover Castle. The second bridge dropped inwards towards the keep. Here the pit seems to have been a break in the causeway, not an archway through it. This bridge also has been replaced in masonry. Each of these drawbridges fell upon cills between small turret buttresses, no doubt intended to strengthen the approach, and to shelter two cross-bow men, who could retire over the bridge as the enemy advanced.

The barbican, at the outer end or head of the causeway, is a mere shell of masonry of irregular shape. It occupies a knoll higher than the causeway, and has a rather steep approach from the town. The gateway opens between two half-round towers, beneath a pointed arch, recessed, but within an outer arch, above which is a projecting parapet, a sort of brétasche in stone. There is no portcullis, and no trace of a drawbridge or outer ditch. The entrance to the causeway is 15 yards behind the great gate, through a hollow way, and the wall between them is looped with six openings looking towards the main ditch. In its rear the barbican rests upon the crest of the cliff, and has a mere parapet. It is prolonged 30 yards to the proper right of the gateway, which it thus flanks, and is strengthened in that direction by two small half-round turrets. In parts of the causeway are loops towards the main ditch, and a doorway, probably a postern, long walled up. The causeway and barbican are later than the keep and main curtain, and probably of the time of Henry III., or rather later. They have been much altered and repaired, and no doubt played a part as outworks in the siege of 1640.

Outside of the natural ravine which forms the main ditch or moat, along the crest of its counterscarp, has been thrown up a bank of earth, probably masking the line of a palisade, intended to keep off skirmishers, and to guard against any attempt at scaling the main wall.

The keep, though mutilated, is still the main feature of the castle. It is a rectangular tower about 56 feet square at the base and about 70 feet high above the inner ward, and about 90 feet from the outer side, where the ground is some 20 feet lower. The walls are 11 feet thick, and of the same thickness to the summit. The west front and a few feet of its adjacent sides are gone, but the foundations remain, completing the square. The material is a sandstone of a deep red colour. The stones are about 2 feet to 2 feet 6 inches long and a foot high, nearly square, and laid with rather open joints. The interior seem to have contained a basement and three upper floors, but the basement is partially filled with earth, and its existence only indicated by a broken loop, seen about 16 feet from the ground on the north front. On the west and north or lower faces the keep has a bold battering base from 15 feet high to 8 feet or 10 feet. This was unnecessary on the other faces where the level of the soil is so much higher.
