The #Choir# is the earliest part of the church. Its two western bays show Carileph's work, but the eastern piers have been considerably altered owing to the addition at a later period of the eastern transept, when Carileph's apses were taken down. This bay contains some very rich and beautiful detail. The piers on either side of the choir are decorated with arcades, the lower stage having six arches, and the upper three, all richly carved with foliage in the caps and hood moulds, and with heads and half figures. There is also a square aumbry on each pier. Above the upper arcade, which breaks through the level of the triforium string course, which is also carried round it, there is on each pier a figure of an angel beneath a canopy. These are the only two figures remaining of many which formerly added to the beauty of the interior of the church. The vaulting of the choir is thirteenth-century work, quadripartite, the ribs decorated with dog-tooth ornament and square leaves, and has fine bosses at the intersections of the diagonal ribs. The choir of Durham is especially interesting to the student of architecture, showing as it does the Early Norman work of Carileph, combined with the Early English and Early Decorated work of the newer eastern portion. On the south side of the choir stands the monument of Bishop Hatfield, who directed the see of Durham from 1345 until 1381. This monument is beneath the Episcopal Throne, which was erected by Bishop Hatfield himself. It consists of an altar tomb surmounted by a recumbent effigy of the bishop, in richly-worked robes, beneath a canopy, richly groined, with foliated bosses at the intersections of the ribs. On the walls at the east and west ends may still be seen the remains of fresco painting, representing in each case two angels. Beneath the staircase leading up to the throne is a very fine decorated arcade, containing several shields bearing the bishop's and other arms. The whole structure was originally richly coloured and gilded, and remains of this work can still be made out. It is a noble specimen of the work of its date. Immediately opposite the tomb of Bishop Hatfield, on the north side of the choir, the visitor will notice the recently-erected memorial to the late Bishop Lightfoot. This is an altar tomb of black and coloured marble. The sides are ornamented with panels of Perpendicular tracery containing shields. Round the upper mouldings runs a Latin inscription in brass. The whole is surmounted by a recumbent figure of the bishop in white marble, his hands on his breast, and his feet resting against three books. Originally designed by Sir Edgar Boehm, R.A., at his death the monument was completed by Alfred Gilbert, R.A.
