Referring to the modern town, Dr. Cosmo Innes says:—
"Reposing on the sunny bank of its own beautiful river, the modern town of Kelso looks a fitting rural capital for 'pleasant Teviotdale.' It has little of the air of an old monastic burgh, and still less calls up any recollection of the heaps of ruins that impeded the plans of the English engineers. There is not much knowledge or tradition of its former state, and but few memorials of its old inhabitants. Last year (1845) a worthy burgher, who had dug up in his garden under the abbey walls what seemed to him a rare coin of a Scotch king, was scarcely well pleased to learn that it was a leaden bulla of Pope Alexander III., bronzed with the oxidising of seven centuries.
In the midst of the modern town the abbey church stands alone, like some antique Titan predominating over the dwarfs of a later world."[420]
Considering all the dangers and neglect of the centuries, it is astonishing that so many of the ruins still exist.
The building has consisted of choir or chancel of considerable length, with north and south aisles, and of a transept and nave without aisles. The north and south divisions of the transept and nave form three arms of equal length round the three sides of the crossing, above which rises the massive square tower.[421] The church was originally constructed in the late Norman style of about the end of the twelfth century, passing into the transition style—the upper part of the tower having been rebuilt at a later period.[422] Of the chancel only a fragment remains—two of the south main piers with arches and two stories of arcades above, which represent the triforium and clerestory. The chancel only had aisles.
The main piers consist of a circular column, five feet in diameter, with smaller attached half-columns on three sides to carry the moulded arches between the main piers and the arches between the latter and the aisles.[423] "The piers have caps of the usual Norman modified cushion pattern, and the arches were moulded and arranged in several orders. The arcade immediately over the main arches has a row of single round shafts, with spreading Norman caps, which carry a series of moulded arches, occupying the position of the triforium. The upper arcade, which takes the place of the clerestory, has shafts of triple form, with wide spreading bases and caps of Norman and transition design. On the latter rest the round boldly-moulded arches. The arches opposite the windows in the outer wall are slightly larger than the others. It will be observed that there is no main vaulting shaft carried up over the main piers, as is almost invariably the case, for the purpose of strengthening the wall. On the contrary, the triforium arcade is continuous, and no provision is made to support the side wall, except the single shafts of the running arcade, which have a very weak effect. In the usual arrangement, the triforium arches are separated by a substantial piece of wall, including a vaulting shaft, and the triforium arch, which is generally subdivided into several subordinate arches, is introduced between the vaulting shafts. That is a much more substantial form of construction, and also more satisfactory to the eye, than the plan adopted here of a simple continuous arcade." In the exterior of this portion of the choir the outside of the clerestory windows is visible, being simple round-headed openings, with flat buttresses between them. The remainder of the wall is plain, but, judging from the level of the triforium window, the vaulting of the aisle, which was very high and partly covered the windows, seems to have been added at a later date. The crossing is square; the piers are about nine feet square—that at the south-east angle standing detached in consequence of the opening into the south aisle, while those at the north-west and south-west angles are incorporated with the walls. The piers are designed as a series of shafts, set in square nooks (four on each of the complete sides), with a large semicircular shaft at each angle. The shafts are all built in courses with the piers, and have transition bases and caps. From the latter spring large pointed arches, with plain chamfered orders. The pointed arch indicates the transitional character of this part of the building, and was probably introduced in this position to give strength to sustain the tower. The three arms of the cross branching to the north, south, and west from the crossing are of equal size—an unusual arrangement, as the nave is generally the longest division of the church. This was part of the original design, as the western doorway is one of the most prominently Norman portions of the edifice, and no satisfactory explanation has yet been given of the shortness of the Kelso nave. The upper portion of the west front has been in the transitional style, and the Norman arcading, which runs round the interior of the nave, was continued across the west end.
The nave, north and south transepts, contain each four stories in height, consisting of an interlacing arcade of Norman work in the interior of the ground level, and three stories of windows above. The upper arcades of the choir do not extend round the nave and transepts, except in a portion of the south transept. The windows in the different stories have all round arches, both inside and outside, and the exterior is marked at each angle by broad and shallow Norman buttresses, with nook shafts in the angles, and an interlacing arcade round the lower story, both internally and externally. In the façades of the west end and north transept the windows of the different stories have been grouped so as to form distinct designs. "In the west end, over the great west doorway, there has been an arrangement of tall windows of apparently lancet form, having on either side an interlacing arcade of round arches, supported on tall, bended shafts. This is now, unfortunately, greatly destroyed. Above the arcade there runs a horizontal flat cornice, enriched with several rows of carved ornaments, and this was surmounted by a large opening of quatrefoil shape, surrounded with numerous mouldings and enrichments. The angle buttresses have been crowned with octagonal turrets."[424]
The north wall of the north transept has a fine transitional door-piece, occupying the two lower stories. The next two stories have each two windows, separated by a small buttress, and the upper story has three arches in the interior. "Above these stories is a small circular window with a curious saving arch over it, and the whole is crowned with a top story, containing three round-headed openings, and a gable with a small circular aperture. The buttresses at the angles are crowned with circular turrets, which have been finished with a projecting parapet, the corbels for carrying which still survive. The upper part of the gable shows signs of having been altered."[425]
The west doorway and the north door-piece are interesting; the former, the south half of which has perished, and which was finished with a sloping gable and stone roof, is regarded as a rich specimen of the elaborate carved work that characterised the late Norman period. "The jambs contained five detached shafts set in nooks, and having Norman bases and carved caps. Over each of these shafts there springs a circular order, carved with rich Norman ornament, now, however, very much decayed. The jambs of the doorway also formed moulded shafts, supporting their order in the arch."[426] The door-piece of the north transept wall is a prominent feature, projects 4 feet 6 inches from the main wall, has two stories, and is roofed with a sloping stone roof. The shafts have the usual Norman caps and bases, and the mouldings of the arch are pronounced to be peculiar in their profile. The outer one is enriched with small medallions, the central with the billet, and the inner one with rosettes. Above the archway there is an arcade of interlacing round shafts—the shafts, which were destroyed, having Norman caps. "The tympanum of the gable is covered with a reticulation of round beads or rolls."[427] The south and west sides and a small portion of the north and east sides of the tower remain. It is 35 feet square over the walls, and "is carried up with plain masonry externally, but the interior has immediately over the great arches of the crossing an arcade of round moulded arches, supported on triple shafts similar to those of the choir. Above this arcade is another story containing simple round arched openings, which are lighted on the exterior by circular windows containing quatrefoils. Over this tier is the upper story, which contains three pointed and deeply-recessed windows on each side of the tower. Broad, flat buttresses are placed at each angle of the tower, similar to those of the main building, and these were, no doubt, originally finished with turrets like those of the transepts.... The upper part of the tower is later than the lower part. This is apparent from the pointed windows of the top story and the quatrefoiled circular windows of the story beneath. The lower story immediately over the great arches is, without doubt, of about the same date as the choir."[428] There were probably similar staircases in other parts of the structure now removed, but the approach to the upper floors is now by one staircase in the N.W. angle of the transept. Passages between the arcades and the outer walls went round the building on every floor, and in the angles of the tower there are small wheel stairs leading to every floor, and passages running round the tower on every story. These arcades and passages have tended to weaken the structure, and it has been found necessary to strengthen it with numerous iron tie-rods, iron beams, etc.[429]
There was an outer door in the S.W. angle of the transept, and another in the north wall of the nave adjoining the crossing. A tomb recess is in the south transept wall, and in the recess beneath are two ambries or lockers and a piscina, the only one remaining in the building. To the south of the transept there is a vaulted chamber that may have been the sacristy.[430]
