Of the houses of this period many yet exist, though not in an entire state; and of these some fine specimens are found in Lincoln,[35] where they are said to have belonged to the Jews, but whose riches at that time only led to their destruction.

Many rich and magnificent examples of monastic buildings of this date occur in various parts of the kingdom.

Norman architecture may be divided into three periods—namely, Early, Middle, or fully-developed, and Transition; the first extending from the Conquest, or a few years previous, to the end of the reign of Henry I., 1135; the second from the commencement of Stephen to nearly the end of Henry II., 1180; after which date the Transition commences, and the style gradually loses its characteristics until it merges in the succeeding, or Early English style of the thirteenth century. Of the first period, the chapel in the Tower of London has been already mentioned as an example; the second includes most of our rich Norman buildings; and of the third, the Temple Church is a good specimen.

The great characteristics of Norman architecture are solidity and strength. Walls of an enormous thickness, huge masses of masonry for piers, windows comparatively small, and a profusion of peculiar ornament, seem to be essential to the full development of the style; and there is a gloomy magnificence in a fine Norman building which is highly impressive; its walls seem as firmly fixed in the earth as the iron foot of the Conqueror was on the neck of a prostrate nation.

The distinctive features of Norman architecture may be thus summarised:—

Towers.—These are in general rather low for their breadth. They are more massive than the Saxon ones which preceded them, and this is particularly the case with the later buildings. Many of the church towers which were built soon after the Conquest have very much of the Saxon character remaining, and are proportionally taller than those of later date, but the workmanship is better. A large belfry window, divided by a shaft, in the upper storey, is a common feature; and the surface of the tower is frequently ornamented with stages of intersecting or plain arcades, and sometimes the whole surface is covered with ornament. The angles of the tower are strengthened by flat buttresses having but little projection, which sometimes reach to the top of the building, and sometimes only to the first or second storey. The parapets of most Norman towers are destroyed, and it is consequently difficult to say what they were originally; but it seems probable that the towers terminated in a pointed roof. Staircases were of common occurrence, and are frequently made very ornamental features. St. James's Tower, Bury St. Edmunds, is an example of an early Norman tower, exhibiting the flat, pilaster-like buttresses, so characteristic of Norman work, and secondly, a porch flanked by two pedimented buttresses, ornamented with corbel-tables and intersecting arcades. The arch is plainer than it would have been at a later period, but it shows the billet moulding which is also used on the buttresses. The capitals are of the plain cushion form, and the pediment of the porch exhibits the scalework surface ornament alluded to in p. 216.

Windows.—These are universally round-headed, except in the Transition period. The simplest form is a narrow round-headed opening, with a plain dripstone; but they are frequently wider, and divided into two lights by a shaft, and richly ornamented with the zigzag and other mouldings.

Doorways.—These are the features on which the most elaborate workmanship was bestowed by the Norman architects, and it is perhaps to be attributed to this that so many of them have been preserved; the Norman doorway having frequently been retained when the church was rebuilt. They are always, except in the Transition period, semicircular, and are very deeply moulded. They are frequently three or four times recessed, and are richly ornamented with the peculiar decorations of the style, the most characteristic of which is the zigzag or chevron moulding. A peculiar head, having a bird's beak, and called a "beak-head," is frequently used, and medallions of the signs of the zodiac are not uncommon. The jambs of the door are ornamented with shafts which are sometimes richly adorned, and have elaborately sculptured capitals. The doorway itself is frequently square-headed, and the tympanum or space between this and the arch is filled with sculpture representing the Trinity, the Saviour, saints, or some symbolical design or monstrous animal, and sometimes merely foliage. There are a few doorways which are trefoil-headed instead of circular.
