We are indebted to the Saxons but for few social improvements; since, in the words of the Wiltshire antiquary, John Aubrey, "They were so far from having arts, that they could not even build with stone. The church at Glaston (bury) was thatched. They lived skittishly in their houses, they ate a great deal of beef and mutton, and drank good ale in a brown mazzard, and their very kings were but a sort of farmers. The Normans then came, and taught them civility and building."

In various parts of England, Scotland, Ireland, and Wales, there are numerous encampments or castles, mostly occupying the summits of hills, which have been ascribed to the aboriginal inhabitants. Amongst the most remarkable are the Hereford Beacon, on the Malvern hills, in Worcestershire; the Caer-Caradock, near Church Stretton, in Shropshire; Moel Arthur, in Flintshire; Chun Castle, in Cornwall; and the magnificent hill-fort, Maiden Castle, or the Castle of the great Hill, within three miles of Dorchester.

Maiden Castle had four gateways of stone; in excavations have been found round stones, probably sling stones, and pottery, denoting its original occupation by Britons; how the fortress was supplied with water has not been traced. This famous earthwork is considered of a period anterior to that of the Britons and Romans: the extent of the work is one mile, and the ramparts are, in some places, sixty feet high. Another famous earthwork in Dorset is Poundbury, a Roman encampment, though it has been set down as Danish, and an Anglo-Saxon camp of council.[22]

Before we leave the Roman period, we may remark that the manufacture of bricks and tiles must then have been known in England, because it was practised in such perfection by our conquerors during their occupation, as is evident in the numerous remains of their buildings.[23] It has, however, been asserted that up to the reign of Elizabeth, the houses of the gentry throughout England were built entirely of timber; whereas, of the mansions of earlier date than that reign, which remain entire or in part to this day, three-fourths, at least, are built of stone or brick. The latter material is stated by Bagford and others to have been first introduced in the reign of Henry VII. Yet, Endure Palace, in Oxfordshire, erected by William De la Pole, and Hurstmonceux Castle, in Sussex, both of which are of brick, are attributed to the reign of Henry VI. Oxburgh Hall, in Norfolk, was erected in the reign of Edward IV. Leland mentions the walls of Hungerford, as early as the reign of Richard II., being of that material; and Stow records Ralph Stratford, Bishop of London, inclosing the burial-ground of Charter-house, for those that died of the plague in 1348, with a wall of brick. That roofing-tiles were in use before the time of Richard I. is proved by the order made in the first years of that reign, Henry Fitzalwayne being Mayor of London, that the houses of that city should be covered with "brent tyle," instead of "strawe," or reeds. The ancient name for bricks appears to have been wall-tiles, to distinguish them from floor-tiles, used for paving.

William the Conqueror lost no time in erecting strong castles in all the principal towns in the kingdom, as at Lincoln, Norwich, Rochester, &c. for the double purpose of strengthening the towns, and keeping the citizens in awe. The Conqueror's followers, among whom he parcelled out the lands of the English, imitated their master's example by building castles on their estates; and so rapidly did they increase, that in the reign of Stephen, or within a century after the arrival of the Conqueror, there are said to have been 1115 castles completed in England alone.

One of the earliest was Conisborough Castle, built by William, the first Earl of Warren, about six miles west of Doncaster: the remains, as far as can be traced, extend about 700 feet in circumference; but the chief object is a noble round tower, strengthened by six massive square buttresses, running from the base to the summit. The extreme thickness of the walls is 15 feet; of each buttress 23 feet; and the entrance is 24 feet from the ground, up a flight of steps. In the centre of the first floor is a round hole, which is the only entrance to a lower apartment, or dungeon. This Castle is chosen by Sir Walter Scott for one of the principal scenes of his romance of Ivanhoe.

Many of the castles of this age were of great size. Instead of a single tower, they consisted of several towers, both round and square, united by walls, inclosing a space called a courtyard, the entrance to which was generally between two strong towers. The whole building was surrounded by a moat or ditch, across which a drawbridge led to the massive doors, which were covered with plates of iron, and in front of them, an iron portcullis—like a harrow, such as we see in the arms of the city of Westminster—was let down the rough, deep grooves in the stonework; whilst overhead projected a parapet, resting on corbels, with openings through which melted lead or hot water could be poured, or stones thrown on the heads of the assailants, who should attempt an entrance by forcing, or, as was the usual mode of attack, by setting fire to the door.[24] The gateways of Caerlaverock, Conway, Carisbrooke, and Caernarvon castles, present good specimens of this kind; as do the Middle Tower, and the Bloody Tower, in the Tower of London: the latter has the most perfect portcullis in the kingdom.

A principal tower or keep rose prominently above the rest, and generally from an artificial mount. It contained the well of water, without which the garrison, when besieged, could not hold out in this their last place of refuge. The keep also had its subterranean prison, and several stories of apartments communicating by a staircase, either in the walls, or built outside the tower.

As the railway traveller journeys along the South Eastern line, he will see close to the Tunbridge station, the towered entrance-gate of the castle built by Richard de Tonbridge, a follower of the Conqueror. The whole building was moated, and the exterior walls inclosed an area of about six acres. There remain only two massive towers flanking an arched gateway, with walls of great thickness, and having no other openings than long narrow slits, called oilets, through which, when besieged, archers shot their arrows. In front of this entrance was formerly a drawbridge, thrown across the moat, which, when raised, formed a strong door, closing up the archway. This opening was again guarded by two portcullises and two thick doors. The towers appear to have been divided into four stories, or floors, the lower being dungeons or prisons, and the upper formed into a large and noble hall, extending the whole width and depth of the two towers. It was lighted by two large windows towards the inner court. The towers are supposed, from their style, to have been built in the reign of King John, or Henry III. The windows were not glazed, but had iron bars; the floor and ceiling were of immense thickness, the latter three feet. Branching from this tower-entrance, are certain walls to the right and left; the first extending up the side of a lofty hill, whereon was the keep-tower, or chief residence of the baron: to this, it is presumed, he retreated when other parts of his castle had been taken by an enemy.

The following account of the siege of Bedford Castle by Henry III., given in Camden's Britannia, is interesting, as containing a summary of the principal portions of the building, and the several stages of the attack:—"The castle was taken by four assaults: in the first was taken the barbican; in the second, the outer bail (ballium); at the third attack, the wall by the old tower was thrown down by the miners, where, with great danger, they possessed themselves of the inner bail through a chink; at the fourth assault, the miners set fire to the tower, so that the smoke burst out, and the tower itself was cloven to that degree, as to show visibly some broad chinks; whereupon the enemy surrendered."
