The town of Jedburgh occupies a site about ten miles south from Kelso, in the narrow valley of the river Jed, a tributary of the Teviot. The main street rises gradually on the west side of the valley till a wider point is reached, on which stood the monastery, above a bend of the river. On a still higher point, at a short distance south of the abbey, stood the Castle of Jedburgh, the subject of constant contention in Border warfare. The position of the abbey on the height above the river as seen from the level “haugh” on the opposite side, with a broad expanse of water in the foreground, is commanding, and forms a very attractive landscape. A Priory of Canons Regular from Beauvais was established here by David I. while Prince of Cumbria, in 1118. In 1147 the priory was raised to the dignity of an abbey, and it was probably after this distinction that the oldest portions of the existing structure were erected. The abbey was dedicated to the Virgin, and was amply endowed by David I. and the nobles of the district. Little is recorded of its history, but the abbots were occasionally men of distinction. In 1285, when John Morel was abbot, King Alexander III. was married in the abbey with much ceremony to Iolanda, daughter of the Count de Dreux. Jedburgh formed a strong Border outpost, and was often attacked and damaged in the wars with England. Under Edward I. the roof of the abbey was stripped of its lead, and the conventual buildings were so damaged that, in the year 1300, the monks had to seek refuge in other houses of their order. During the fifteenth century the abbey frequently [Illustration: FIG. 363.--Jedburgh Abbey. Plan.] suffered from hostile invasion, and in consequence had to undergo considerable repairs, as will be pointed out in connection with the crossing and tower. [Illustration: FIG. 364.--Jedburgh Abbey. South Side of Choir.] Notwithstanding the frequent harrying and damage it sustained, the fabric of the Abbey Church is still in a wonderful state of completeness, but the monastic buildings which stood on the south side of the church have been entirely swept away. The church (Fig. 363, Plan) consists of a choir, with side aisles extending eastwards for two bays, beyond which was an aisleless presbytery, the east end of which is demolished; a nave of nine bays, which had vaulted side aisles (now greatly destroyed); a central crossing, with a square tower above; a north transept, well preserved; and a south transept, of which the south end is destroyed.
