The façade of the south transept (Fig. 760) retains a portion of its circular window, the tracery in which, like that of the great western window, has apparently given way, and has had to be partly built up in a similar manner with solid masonry. This portion of the church possesses a few features which seem to point to it as the oldest remaining part of the edifice. The forms of the windows indicate a somewhat earlier date than the rest of the church. A small portion of the triforium in the north transept (Fig. 761) has been spared, which shows that it has been similar in design to that of the nave. The choir (see Fig. 761) is without aisles, and is 50 feet long by 28 feet wide, and divided into three bays. It is lighted with one large traceried east window and two traceried windows on each side; and the tracery, as rarely happens in Scotland, is still preserved. It is a peculiarity of this structure that most of the arches are depressed, the centres from which the arches are struck being below the level of the capitals; and this peculiarity is particularly apparent in the great east window of the choir. [Illustration: FIG. 760.--New Abbey, or Sweetheart Abbey. View from South-West.] [Illustration: FIG. 761.--New Abbey, or Sweetheart Abbey. Choir, from Crossing.] is also noticeable in the side windows and throughout the building, even the arches of the main arcades of the nave having, as already pointed out, a similar form. The inner mouldings of the window arches by this arrangement abut against or die into the jambs, a form not in itself displeasing; but the incompleted and broken appearance of the arches of the hood at the face of the wall cannot be regarded as beautiful. Some further peculiarities are also to be noticed in connection with the tracery. A prominent moulding is carried round the mullions and the lower arches only of the eastern window, while the upper parts of the tracery are plain and rather heavy in appearance. In the case of the side windows of the choir a similar moulding is carried round the whole of the tracery, and the effect, owing to the depression of the arches, is somewhat squat and heavy. The most beautifully detailed feature of the church is undoubtedly the triforium. Although now only well preserved in the nave, it has originally gone round the whole edifice, small portions of it being still preserved, as above mentioned, in the triforiums of the transepts and choir (see Fig. 761). In the two latter places it has been simpler than in the nave, the caps being moulded in these situations, and beautifully carved with foliage in the nave. The semicircular arch of the upper window in the east gable (Fig. 762) of the choir and the similar form in the exterior windows of the triforium of the nave (see Fig. 757) are quite in accordance with Scottish usage, and give no clue to the date. The sedilia and piscina of the choir have been of fine workmanship, but are now sadly destroyed.
