It is here that the choir of about twenty-two boys and twelve Lay Vicars sings the daily services. The boys are educated at the Choir School attached to the Abbey ;mention of such a school is made in the fifteenth century and it may be even older in origin. For some centuries it was linked with Westminster School, but became independent in the mid-nineteenth century.

The Organ was originally built by Shrider in 1730. Successive rebuildings in 1849,1884,1909,,and 1937 and extensive work in 1983 have resulted in the present instrument.

THE SANCTUARY is the heart of the Abbey, where the High Altar stands The altar and the reredos behind it, with a mosaic of the Last Supper, were designed by Sir Gilbert Scott in 1867. Standing on the altar are two candlesticks, bought with money bequeathed by a serving-maid, Sarah Hughes, in the seventeenth century. In front of the altar, but protected by carpeting, is another of the Abbey’s treasures - a now-very-worn pavement dating from the thirteenth century. The method of its decoration is known as Cosmati work, after the Italian family who developed the technique of inlaying intricate designs made up of small pieces of coloured marble into a plain marble ground.

THE NORTH TRANSEPT, to the left of the Sanctuary, has a beautiful rose window designed by Sir James Thornhill, showing eleven Apostles. The Transept once led to Solomon’s Porch and now leads to the nineteenth-century North Front.

THE HENRY YII CHAPEL, beyond the apse, was begun in 1503 as a burial place for Henry YI, on the orders of Henry YII, but it was Henry.YII himself who was finally buried here, in an elaborate tomb. The master mason, who designed the chapel was probably Robert Vertue his brother William constructed the vault at St George’s Chapel, Windsor, in 1505 and this experience may have helped in the creation of the magnificent vaulting erected here a few years later.

The chapel has an apse and side aisles which are fan-vaulted, and the central section is roofed with extraordinarily intricate and finely-detailed circular vaulting ,embellished with more Tudor badges and with carved pendants, which is literally breath-taking in the perfection of its beauty and artistry.

Beneath the windows, once filled with glass painted by Bernard Flower of which only fragments now remain, are ninety-four of the original 107 statues of saints, placed in richly embellished niches. Beneath these, in turn, hang the banners of the living Knights Grand Cross of the Order of the Bath, whose chapel this is. When the Order was founded in 1725, extra stalls and seats were added to those originally provided. To the stalls are attached plates recording the names and arms of past Knights of the Order, while under the seats can be seen finely carved misericords.

The altar, a copy of the sixteenth-century altar incorporates two of the original pillars and under its canopy hangs a fifteenth-century Madonna and Child by Vivarini.

In the centre of the apse, behind the altar, stand the tomb of Henry YII and Elizabeth of York, protected by a bronze screen. The tomb was the work of Torrigiani and the effigies of the king and queen are finely executed in gilt bronze.

In later years many more royal burials took place in the chapel. Mary I, her half-sister Elizabeth I and half-brother Edward YI all lie here The Latin inscription on thetomb - on which only Elizabeth Ist effigy rests - reads: «Consorts both in throne and grave, here rest we two sisters, Elizabeth and Mary, in the hope of one Resurrection».

In the south asle lies Mary Queen of Scots, mother of James Yi and I, who brought her body from Peterborough and gave her a tomb even more magnificent than that which he had erected for his cousin Elizabeth.I.

In the same aisle lies Henry YII’s mother, Margaret Beaufort, Countess of Richmond. Her effigy, a bronze by Torrigiani, shows her in old age. She was known for her charitable works and for her intellect - she founded Christ’s and St John’s Colleges at Cambridge - and these activities are recorded in the inscription composed by Erasmus. Also in this aisle is the tomb of Margaret, Countess of Lennox.

THE CHAPEL OF ST EDWARD THE CONFESSOR, containing his shrine, lies east of the Sanctuary at the heart of the Abbey. It is closed off from the west by a stone screen, probably of fifteenth-century date, carved with scenes from the life of Edward the Confessor; it is approached from the east via a bridge from the Henry YII Chapel.

The shrine seen today within the chapel is only a ghost of its former self. It originally had three parts: a stone base decorated with Cosmati work, a gold feretory containing the saint’s coffin, a canopy above which could be raised to reveal the feretory or lowered to protect it. Votive offerings of gold and jewels were given to
