Tombs A tomb in the choir incorporating a much-restored female effigy is widely believed to be that of Marjorie Bruce. Although there is no evidence that she is buried at exactly that location, her remains are thought to be within the abbey. The tomb is reconstructed from fragments of different origin - the base, is likely to have originally formed part of the pulpitum of the Abbey (a stone screen separating nave and choir), such as survives at Glasgow Cathedral. Opposite Marjorie Bruce lie the tombs of Robert III of Scotland and Simon fitz Alan. A Latin inscription commemorates the three children of Margaret Seton and Claud Hamilton, 1st Lord Paisley who died as infants; Margaret (1577), Henry (1585), and Alexander (1587). Stained glass Stained glass (removed in the Reformation) began to be replaced in the 1870s. Major works include a window by Edward Burne-Jones and the huge east window by Douglas Strachan. The dramatic memorial window to James D. D. Shaw dates from 1989 and is by John Clark. Abbey organ The Abbey organ is reputedly one of the finest in Scotland, and was originally built by the most distinguished of all 19th-century organ builders, Cavaillé-Coll of Paris in 1872. This is one of only six in the UK. Since 1872 it has been rebuilt and extended four times. The organ as rebuilt by Walker in 1968 has 4 manuals, 65 stops and 5448 pipes.(National Pipe Organ Register; "The Organ at Paisley Abbey", booklet pub. Paisley Abbey) In 2009 the instrument underwent a major restoration by Harrison and Harrison of Durham. The work included major cleaning and servicing, the provision of a new wind system and the addition of a 32 ft contre bombarde. The latter was part of the 1968 scheme by Ralph Downes but not included in the work actually undertaken.
