Cathedrals are all similarly located as to the points of compass, and the principal entrance is in the west end. The one mentioned is about five times as long as it is wide. The wall is relieved by a large transept, the east wall of which begins about one third the distance from the east end. This gives the building the form of a cross. The part from the west end to the crossing of the transept is called the nave. The ends of the transept extend about one-third of the width of the building. The nave is flanked by avenues on each side, narrower and lower than itself, called aisles. They are separated from it by a row of columns or piers, connected by arches. Thus the nave has an arcade on each side, and each aisle has an arcade on one side, and the outer wall pierced by windows on the other. The strong arches of the arcade carry the walls that rise above the roofs of the aisles. These walls are usually divided internally into two stories. The lower story consists of a series of smaller arches, forming a second arcade, called the triforium, that opens into the dark space above the ceiling of the aisles, and is hence called the blind story.

The upper story has a range of windows, giving light to the nave, and is called the clere-story. Thus a spectator standing in the nave and looking toward either side, will see before him the main arcade and side windows, above the arcade the triforium, and above this the clere-story, beautifully illuminated and crowned with the nave, vault or roof. The great size and height give sublimity to the sight. The east arm of a cathedral is that to which most importance is attached, and has greater richness and more elaborate finish.

When the termination is semi-circular or polygonal it is called an apse or apsidal east end. Attached to some of the side walls it is usual to have a series of chapels, partially shut off from the main building, yet of easy access.

Tombs and enclosures connected with them, called chantry chapels, are met in various positions, especially in the eastern arm. Below the raised floor of the choir there is a subterranean vaulted structure called the crypt.

Passing to the exterior, the principal doorway is in the west front, deeply recessed, and elaborate in design. There are also doors in both ends of the transept, and one or more side entrances. In a complete cathedral the grand architectural effect is principally due to the towers with which it is adorned, the most massive standing at the crossing of the transept.

To cathedrals and abbey-churches a group of monastic buildings was attached; sometimes very expensive and in the best style of the art. The most important of these is the Chapter House, which is frequently lofty and highly ornamented. The extent and arrangement of the monastic buildings adjoining the cloister vary with the needs of the different order of monks. The monk’s dormitory was on the east side of the great cloister, the refectory and kitchen on the south, and on the west the great cellar, and a hospitum for the entertainment of guests.

The house for the abbot, the infirmary, the school building for novices, with its chapel, and more remotely the granaries, mills, bake-houses, offices, garden, cemetery—taken all together, a monastery shows an extensive group of buildings well arranged for the purposes intended.

Some military and domestic buildings are also of great interest. In those centuries dwellings of much consequence were all more or less fortified. Some were built with a lofty square tower, called a “keep,” and capable of standing an assault or a siege. The number and character of the buildings in the enclosure around the keep of course depended on the ability of the proprietor. The outer buildings of the Tower of London, though much modernized, give a good idea of what a first-class castle grew, by successive additions, to be. In those erected near the close of the thirteenth century, the square tower was abandoned, and better provision made for the comfort and convenience of the occupants.

Warwick Castle might be cited as a good example of an English castelated mansion, of the time of Richard II. But still more interesting is Haddon Hall, the residence of the Duke of Rutland, in Derbyshire. It consists of two internal quadrangles separated by the great hall, with its dais, its minstrel’s gallery, its vast open fire-place, and its traceried windows. Probably nowhere in England can the growth of domestic architecture be better studied, whether we look to the alterations which took place in arrangement, or to changes in the treatment of windows, battlements, doorways, and other features, than at Haddon Hall.

English Gothic architecture has generally been divided into three periods: The Early, the Decorated, and the Perpendicular. The following condensed list of the peculiarities of each period will be found useful for reference. Early English: General proportions more slender, and height of walls and columns greater; arches pointed, generally lancet, often richly moulded; triforium and arcades often with trifoiled heads. Piers were more slender, composed of a central shaft surrounded by several smaller ones almost or quite detached; capitals concave in outline, moulded or carved with conventional foliage, delicately executed. The windows were at first long, narrow, and deeply splayed internally, the glass being within a few inches of the outer face of the wall; later in style more acute, divided by mullions, enriched with cuspated circles in the head, and often with three or more lights—the center lights being the highest. Doorways were deeply recessed, enriched with slender shafts and elaborate mouldings. Buttresses were about equal in projection to their width, with but one set off, or without any. The mouldings were bold and deeply undercut.
