In the next arch is a large Decorated structure of two stories, believed by Scott to have been built by Walsingham as the base for the shrine of S. Etheldreda. It was formerly known as Bishop Hotham's shrine, and his effigy was placed beneath it. The lower story is open.

In the arch north of the altar is the tomb of the builder of the presbytery, Bishop Northwold (d. 1254). He is represented in full vestments. At the east of the tomb is a curious carving, apparently meant for the martyrdom of S. Edmund. A king naked above the middle, except for his kingly crown, is tied to a tree and pierced by arrows; archers with drawn bows are behind; at one end the king has his head, still crowned, in his hands, with a figure bearing a sword over him; at the other side is either the wolf of the legend or an evil spirit in animal shape.

In the aisle itself are several memorials, mostly of the eighteenth century, that call for no special mention. The latest is the brass to Mr. Basevi, 1845.

At the east end of the aisle is the Chapel Of Bishop Alcock (d. 1500). The date, 1488, is fixed precisely by the inscribed stone now placed in the wall above a small stone altar. The stone in the wall has five crosses, as though intended for a chantry altar, but the slab of the altar beneath has no crosses. The inscription is, "Iohanes Alkoc epus Eliesis hanc fabricam fieri fecit M cccc iiij(xx) viij." The sides of the chapel are covered with niches, canopies, crockets, panels, and devices. The roof has fan tracery with a massive pendant. A singular little chantry is at the north, access to which is through a door at the foot of the bishop's tomb. In a small window here is a little contemporary stained glass. The bishop's rebus—a cock on a globe—repeatedly occurs in the stone-work. The ornamentation strikes the spectator as being excessive and too profuse. No figures have been replaced in the niches.

In the retro-choir a mosaic slab over the remains of Bishop Allen (d. 1845) has a curious history. A son of the bishop was passing through Paris soon after Napoleon's tomb was finished, and the surplus materials were offered for sale by auction. Some of these were purchased by Mr. Allen and utilised for the slab over the bishop's grave. The large monument to Canon Mill (d. 1853) has an effigy in copper on a support of marble and alabaster; students of India and Cambridge are by the feet.

The tomb of Cardinal Luxemburg (d. 1443) is beneath the most eastern arch on the south, just north of Bishop West's chapel. When the monument was concealed behind some wood-work great dispute arose as to the headdress of the effigy. Bentham has an engraving with a cardinal's hat on the archbishop's head. Cole records that it was a mitre. When the wood-work was removed it was found that the figure was headless, as it still remains.

Corresponding to the chapel of Bishop Alcock on the north is that of Bishop West (d. 1533) in the south aisle. This is a most valuable example of the Renaissance style. The niches and canopies with which the walls are covered are much smaller than those in the other chapel, and consequently more numerous; but by reason of the great delicacy of the tracery and the wonderful variety of the designs there is no impression that the decoration is overdone. No perfect specimen is left of the statues or of the heads which were introduced in the tabernacle work; and in its complete state this exquisite work can have existed for not more, than twelve or thirteen years, as the Order in Council for removing images was made in 1548. The roof is curious, as being an adaptation in the Renaissance of the late Gothic fan tracery Some colouring remains. The wrought-iron gates, with motto in Latin several times repeated, and the curious little pendants from the roof, consisting of angels bearing shields of arms, should be noticed. Bishops Greene (d. 1738), Keene (d. 1781), Sparke (d. 1836), and Woodford (d. 1885) are all buried in this chapel. On the south side, within a shrine-like receptacle, have been placed the relics of seven early benefactors of the church. Originally buried in the Saxon church, they have been several limes removed. They were placed here in 1771. The names are carved in seven shallow niches. One was an archbishop, five were bishops, and the seventh was Alderman Brithnoth. The dates range from 991 to 1067.
