§ 51. The rebuilding of the south aisle, about 1313, at Newark, was the prelude to an entire rebuilding of the church, which extended over many years. The builders began by setting out their aisles as usual, and by the middle of the fourteenth century the south aisle was finished, and the lower courses of the north aisle and the new aisled chancel were built. However, in 1349, the Black Death interrupted the work. The north aisle and chancel were not completed, and the new arcades of nave and chancel were not built until the fifteenth century. In this case there were certainly older, and almost certainly narrower aisles. The rebuilding included aisles on a larger scale, and new internal arcades whose spacing corresponded to the spacing of the aisle walls. All systematic rebuilding, in the full development of Gothic art, began with the planning of the aisles. The naves of Cirencester and Northleach churches, rebuilt at the end of the middle ages, are examples of this method. The arcades at Cirencester are known to have been built about 1514-5; but the aisles were obviously completed first, and their remodelling may have been begun in the second quarter of the fifteenth century. At Northleach the nave was finished about 1458; and there seems to have been a break of some years between the building of the aisles and the destruction of the older church which, no doubt, lay within them. But it did not always happen that the full intention of the builders was carried out. One of the most splendid schemes which we possess for the enlargement of a parish church was the great enterprise begun at Grantham soon after the middle of the thirteenth century. An aisleless Norman church had been enlarged at the end of the twelfth century by the addition of aisles to the nave, the connexion being formed by arcades of rounded arches springing from very elegant clustered columns. Above the arcades were low clerestories, lighted by round-headed windows. About 1230, the neighbouring church of Newark was taken in hand by masons, who built a new west tower up to a certain height, and, as an afterthought, planned aisles to engage the tower completely. As we have seen, the building of the aisles at Newark upon their present scale did not begin till much later. The work of rebuilding at Grantham was clearly inspired by that already begun at Newark. A tower was planned on a site much to the west of the nave, and was engaged within very broad aisles. The tower and north aisle were set out first. The north aisle was divided into seven bays, with a large traceried window in each bay, the western bay being much wider between the buttresses than the rest, owing to the greater space taken up by the tower and its piers internally. The remaining six bays were set out with equal widths between the buttresses, the middle bay of the aisle being covered by a porch. The eastern bay overlapped the western part of the aisleless chancel, its western buttress being in a line with the division between chancel and nave. The western bay of the south aisle was set out about the same time, and there was, no doubt, an intention of proceeding with the rest on the same lines as in the north aisle. There can also be little doubt that the builders intended to take down the old arcades, and build new arcades, with spacing corresponding to that of their aisles, and to lengthen the chancel eastwards, while bringing its western portion into the nave. The tower and north aisle were built on the intended scale; and, when the tower had risen to a certain height, the ambition of the builders was fired to add to it an extra stage, hitherto uncontemplated, below the spire with which it was to be crowned. This project of giving their church a tower and stone spire, which remained, for many years, the loftiest in England, evidently curtailed the full accomplishment of their earlier plan. The columns of the old arcades were kept, and the tower was connected by arcades of two bays with the angles of the west wall of the old church; while an arch was pierced through the north wall of the chancel, to give access to the east bay of the new aisle. The new arches were pointed: in order to match them, the older round-headed arches were taken down, and pointed arches built, which cut into and blocked the clerestory windows. This change was made with great economy of material, the springing stones of some of the old arches being kept to afford footing for the new. When the south aisle was seriously begun, about 1300, similar economy was shown. Four bays, in addition to the western bay, were spaced out, without regard to the plan of the north aisle. The fourth bay from the west was covered by a porch, smaller than that on the north side; and the east wall of the aisle was probably built on a line with the division between nave and chancel. Half a century later, the east wall was taken down, and the south aisle was extended to the full length of the chancel; but this later development was not contemplated by the thirteenth century builders. These hesitations and changes, consequent upon the expense entailed by the north aisle and by the alteration in the elevation of the tower and spire, make Grantham second to no English church in interest.

§ 52. Grantham also provides us with a lengthened nave. The position of its earlier west wall is clearly shown by the masses of masonry which occur between the eastern bay of the new, and western bay of the old, arcade on either side. The responds on the eastern side of these pieces of wall are twelfth century work: on the west side, they belong to the later part of the thirteenth century. Such lengthening was probably very common in later Gothic times, and we may surmise that it took place in many instances where arcades were entirely rebuilt, and no visible trace of the process was left. However, there are many churches in which one or more extra bays have been added to the nave, and the join of the old and new work is marked as at Grantham. Whaplode church in south Lincolnshire had its early twelfth century nave lengthened by three bays about 1180. At Colsterworth, near Grantham, a western bay was added to the nave about the same time, and an earlier north aisle lengthened. Above the piece of wall which occurs between the older and newer work, the quoins of the aisleless church remain entire. Usually, as at Grantham, the lengthening of the nave was undertaken in connexion with a new western tower, which was built up outside the church, and then connected with it by one or two bays of arcading. Almost contemporary with the tower and spire of Grantham are those of Tilney All Saints, near Lynn. Here a single bay was added west of the late twelfth century nave; and, as no new aisles were contemplated, the old arcades, with their rounded arches, were left intact. Bubwith in Yorkshire, and Caunton in Nottinghamshire, are later examples of churches where the tower was built west of the end of an earlier nave, and a bay was built to connect it with the older work. Sometimes, as at Gretton in Northamptonshire, where the slope of a steep hill forbade extension far to the west, a new tower was built only a few feet beyond the limit of the old nave. In such a case, the side walls of the nave might be carried solid westwards to meet the tower, or, as happened at Gretton, narrow arches might be made between the tower and the west end of the older wall. The beautiful tower and spire at Oundle were built just outside the west wall of the thirteenth century nave; and were doubtless intended to be followed by a complete rebuilding of the arcades—such a rebuilding as took place at Lavenham in Suffolk, towards the end of the fifteenth century. The idea, however, was abandoned, and the space between the arcades and the tower filled in solid with rather rough masonry.

§ 53. The position of the western tower in the plan is normally at the west end of the nave, with which it is connected by an arch, low at first, but loftier as time goes on, until, in later Gothic churches, its height frequently is nearly that of the whole nave. The remaining three walls are usually external, and clear of the aisles. But sometimes, owing to a freak of planning, or, more frequently, owing to the conditions of the site, the tower is, as at Bibury, at the west end of one of the aisles. At Gedling in Nottinghamshire the tower and spire are at the end of the north aisle. The tower of St Michael's, Cambridge, is at the west end of the south aisle: probably the western extension of the church was prevented by the neighbourhood of the street, a circumstance which often accounts for the irregularity of plan in some town churches. At St Mary Redcliffe, Bristol, built on the edge of the "red cliff" from which it takes its name, the tower and spire are at the end of the north aisle: had they been planned in the usual place, a full bay of the nave would have been sacrificed. The tower at Spalding was planned, in the first instance, to stand against the south wall of the west bay of the south aisle: subsequently a new south aisle was built east of it. One of the most curious instances is that of St Mary's at Leicester, where the tower, subsequently, as at Spalding, heightened by a spire, was planned in the thirteenth century, outside a very narrow south aisle. A tower at the west end of the nave would have encroached upon the inner ward of the adjacent castle. The chancel of St Mary's was used for collegiate services, and parochial accommodation was limited. Towards the end of the thirteenth century, a very wide south aisle, a parish church in itself, was built the full length of the nave, and overlapping the chancel at the east end. The tower was left standing on piers entirely within the west end of the new aisle. It may be added that, where towers occur at the end of aisles, they seldom project beyond the west wall of the nave, but open into the nave by an arch in the north or south wall, as the case may be. Plans with two western towers, as at Melbourne or St Margaret's at Lynn, are of very rare occurrence; and, where they are found, the plan was probably designed on more ambitious lines than those of the ordinary parish church.

§ 54. The plan in which the western tower is engaged within the aisles—that is, where the aisles are brought up flush with the west end of the church—is not very common. Still, instances occur in all parts of England. At Grantham, the plan is deliberate. It was imitated, as has been said, from Newark, where the side walls of the tower had been pierced with arches as an after-thought. Newark, in turn, may have taken the design from Tickhill in south Yorkshire; and the design at Tickhill may have been taken from the early and unpretentious example at Sherburn-in-Elmet. Grantham probably suggested other similar designs, such as Ewerby, near Sleaford. Several of our finest late Gothic churches, like St Nicholas at Newcastle, have plans in which the aisles are continued up to the west face of the tower. The method affords full development to the aisles, and, as at Sileby in Leicestershire, has an imposing interior effect. Outside, however, the aisles crowd the base of the tower too much, and the fine effect of a lofty, free standing tower is lost. Sometimes aisles were extended westwards, so as to engage an earlier tower, as at Sleaford, where the low tower and spire are almost overwhelmed by a pair of wide fourteenth century aisles. At Brigstock and Winterton, late Saxon towers have been left without alteration inside aisles which have been brought westward in the thirteenth and fourteenth centuries. The nave of Holy Trinity, Cambridge, was much widened in the fourteenth century, and a small tower and spire of earlier date were brought entirely within the new nave, as happened in the south aisle at St Mary's, Leicester, and were left without sufficient abutment. As a consequence, the arches of the ground story had to be strengthened about a century later with additional masonry. Cases occur, as at Coln Rogers in Gloucestershire, where a tower has been built within the west end of an earlier church. In most of such instances, the churchyard boundary probably allowed of no further building westward. The nearness of the churchyard boundary also seems to have given cause to a peculiarity which may be seen at Wollaton, near Nottingham, Dedham in Essex, and in a few other places, where the west tower is in its usual position, but is pierced from north to south by an archway. It is possible that this gave facility to processions, which could thus pass round the church without leaving consecrated ground. The tower of old All Saints, Cambridge, now destroyed, projected over the public foot-way of the street, which passed through its ground story; while St John's, Bristol, is built on the city wall, and the tower and spire, which it shared with the adjoining church of St Lawrence, are over the south gate of the city.

§ 55. Sometimes, as at Oundle, the tower was rebuilt with a view to the reconstruction of the whole church. But, as also at Oundle, the design was often abandoned, or was altered. The magnificent tower of St Michael's, Coventry, was built, between 1373 and 1394, at the west end of an older nave: its spire was not begun till 1430. Whether the rebuilding of the nave was contemplated when the tower was begun, it is impossible to say. A new nave was actually begun in 1432, and finished in 1450. A thoroughfare immediately south of the church prevented extension on that side. The old south porch was retained in place as the principal entrance, so that the line of the wall of the south aisle follows closely that of the original church. The new south arcade was set out, not in a line with the south-east buttress of the tower, but somewhat to the north of it, so that the buttress is external; while, for the width of the nave, a space approximating to twice the internal breadth of the tower was taken. The tower is thus placed almost wholly south of the central axis of the nave produced westward. Here, once more, we may note the influence of site on the plan.
