From the existence of the large west end pillars, it was evidently intended from the first to have two western towers. The northern one, along with the upper part of the adjoining gable, was destroyed to a considerable extent at the Reformation, and in its present state it was designed and built up by William Schaw. The bold corbelling at the top recalls the similar treatment of the towers of St. Machar's, Aberdeen, and other examples derived from domestic architecture.[347] The south-west tower seems to have remained intact, although in a ruinous condition, till 1807, when it fell, having been struck with lightning. Three years later the present top was put on the old walls.[348] The Lady Chapel at the east end was built to receive Queen Margaret's shrine, and is now reduced to a small fragment, consisting of part of the south and east walls, which remain to the height of about 2 or 3 feet. "It has been a small structure of about 26 feet 9 inches by 22 feet, of delicate and refined pointed work, as is apparent from the bases of the wall arcading and the edge of the surrounding seat, enriched with nail-head ornaments, which still exist. The Lady Chapel appears from an old view to have been a low structure, reaching only to the sill of the great east window of the choir, and it was evidently vaulted in two compartments."[349] No stones now remain of the thirteenth century choir, as they were all removed to make room for the modern church, begun in 1818; before this, however, considerable remains of the choir and the whole of the foundations were standing.[350] The choir was a prolongation of the present nave, having transepts and a great aisle on the north side. There was a lofty central tower of two stories, with three windows in each storey facing the four sides, and it was this part of the structure which suffered on the 28th March 1560, when "the wholl lordis and barnis that were on thys syde of Forth passed to Stirling, and be the way kest doun the Abbey of Dunfermling."[351] The nave was used as a parish church till 1821, when the new choir was opened. In the south transept of it are three much-admired white marble monuments: General Bruce's by Foley (1868), the Hon. Dashwood Preston Bruce's by Noble (1870), and Lady Augusta Stanley's by Miss Grant of Kilgraston (1876). The remains of King Robert the Bruce were discovered in 1818 at the digging for the foundation of the new parish church. They were found wrapped in a pall of cloth of gold, thrown apparently over two coverings of sheet lead, in which the body was encased, all being enclosed in a stone coffin. "There was strong internal evidence of the remains being those of Robert Bruce, and after a cast of the skull had been taken, they were replaced in the coffin, immersed in melted pitch, and
