Passing under this gallery, through the door of the choir screen, the visitor stood in the central sanctuary, the church of the monks of the cloister. On either side were twenty stalls, and against the screen, facing the east, were three stalls on the right of the entrance, and three on the left. The number of the stalls is determined by the discovery of nine earthen pots buried in the masonry which underlay them. These pots were, no doubt, as in several other churches, an acoustic experiment. The distances between them indicate how many there were in the whole range. In front of the stalls of the monks were lower seats for the novices. In addition to the entrance through the choir screen, there were two other ways of access, at the east end of the stalls, on either side. Here is still on either side a stone step, significantly worn. On the north side, stairs led to a high seat over the door. In the middle alley, where the lecturn may have stood at which the lessons were read at matins, an abbot was buried. The presbytery, or chancel, began at these choir doors, and was raised a step or two. Across the long space of its shining floor stood the third partition, called the altar screen. Against it was the high altar. Thus the church was divided into three churches; one for the brothers of the cellarium, ending at the rood screen; one for the infirmary brethren, ending at the choir screen; one for the brethren of the cloister, ending at the altar screen. On the two sides of this three-fold sanctuary ran long aisles, from the west wall to the chapel of the nine altars. In the middle of this distance, the aisles opened into transepts, north and south. The nave aisles, at first unobstructed for passage around the church, were presently cut up by cross partitions into chapels; but the choir aisles continued to be used as ambulatories. The transepts served as antechambers for the chapels which opened out from them to the east. Each transept had originally three of these chapels, but the building of the new chancel had taken away the inner one on each side. Of the two which thus remained, the outer chapel of the north transept had been changed into a store-house when the tower was built, so that only the chapel which was in the middle remained. Over the door, under a bracket, is still to be read an inscription which informs us that it was dedicated to the Archangel Michael. The north transept ended in the noble tower of four storeys, the third of which was probably for the bells, whilst the second may have served as the sleeping-room of the men who rung them. The inscriptions which ran round the outside of the tower are still in great part legible. “Blessed be the name of Jesus Christ,” said the stones above. “Blessing and wisdom and honour and power be to our God for ever”; “To the King, eternal, immortal, invisible, be honour and glory for ever,” said the middle lines.
