Bishop Langton also erected the shrine of St. Chad at an expense of £2000. This shrine stood behind the high altar in the most eastern bay of the retro-choir, and, as was usual, had on its western side an altar dedicated to the saint. A similar arrangement can still be seen in Westminster Abbey, where the shrine of Edward the Confessor stands behind the reredos. The space behind the reredos, with the corresponding bays of the aisles, were in the past called the lady choir. This portion was separated from the rest of the choir by the reredos in the centre, and by screens in a line with the reredos in the aisles; there was a chapel in the lady choir at the end of each aisle, but to whom they were dedicated is doubtful. Stukeley, writing in 1715, says: "In St. Peter's Chapel, which is now a place to lay scaffolding and ladders, etc., was painted upon the wall St. Peter crucified with his head downwards, and two other apostles, etc. And in this place is the noted St. Chad's tomb, though defaced, removed from the lady choir to be put here since the Restoration." The same writer also tells us that: "Over across the middle of the said choir was a rood loft, finely carved and gilded, and St. Chad's shrine, but destroyed in time of war."
Professor Willis has pointed out the singular parallelism between the development of this cathedral and that of York. "The Norman Cathedral of York was built in 1080, and that of Lichfield at an uncertain date. Between 1154-1181, Archbishop Roger substituted for the original chancel at York a long, square-ended choir, with the aisle carried behind the end. At Lichfield, during the same period, the large chapel was built at the end of the Norman apse; and about the beginning of the thirteenth century the whole Norman eastern termination was, as at York, replaced by a long, square-ended choir with the low aisles behind. Next, at York the Norman transepts were rebuilt in Early English: the south transept, 1230-1241; followed by the north transept, 1241-1260. Also at Lichfield the Norman transepts were rebuilt in Early English, beginning with the south and ending with the north. The Early English work of this cathedral is shown by the licences to dig stone to have been in progress in 1235 and 1238. York nave and Lichfield were next rebuilt in Early Decorated--the first in 1291-1324. Lastly, at Lichfield, the elongation of the eastern part was begun at the extreme east, beyond the existing choir by the Lady Chapel, in late Decorated under Bishop Langton, 1296-1321, and followed by taking down the choir, and continuing the same work on its site westward. The works at York followed in the same order, but forty or fifty years later, by first erecting the presbytery outside the existing choir, and then taking down the latter and continuing the work of the presbytery to form the new choir. The plans of the two cathedrals rival each other in the simplicity of their proportions."
