The series of basins of Alwalton marble was found, during the recent underpinning of the west front, in use as foundation stones; they appear to be of late Norman date. One window in the north transept aisle and all three in the south have fine geometrical tracery. The three chapels in the south transept were used as vestries until a few years ago, when the space beneath the bell-tower and part of the north aisle of the nave was converted into a large vestry for both clergy and choir. In the chapel here nearest the choir there remains the lower part of the newel staircase which led to an upper chapel. On the west side of the south transept has been erected a building which has in its time served many different purposes. It can hardly be called an aisle, as there is only access to the transept by a single ogee-headed doorway, which is a Decorated insertion. This building is of late, almost transition, Norman date; and is not very many years later than the transept itself. It can be seen from the cloister court that it had originally three gables. The roof is vaulted. In an inventory of goods made in 1539, printed in Gunton, there is one chapel described as the "Ostrie Chapel," which is believed to refer to this building. In a plan drawn in Bishop Kennett's time and dedicated to him, the south part is called "The Hostry Chapel, now the Chapter-House," and the north part is called the "Chapel of St. Sprite or the Holy Ghost." In some plans it is called the vestry. It has also been employed as a muniment room, as a Chapter-house, and (as now) as a practising room for the choir. [Illustration: The Transepts, looking North.] Near the south-western pier of the central tower access can be obtained to what remains of the =Saxon Church=. It was when the foundations of this pier were reached, in 1883, that the first indications of an earlier building were brought to light. First a solid piece of wall was discovered, and soon after a substantial piece of plaster attached to the wall, running north and south, which has since proved to be the eastern wall of the north transept of the Saxon Church. The workmen also came upon a plaster floor, on which were remains of burnt wood, reddened stone, and other evidences of a conflagration. As the work of excavation proceeded at intervals, fresh discoveries were made. The walls of the north transept, choir, and part of the south transept, can be traced. Just outside the eastern wall can be seen portions of two Saxon tombs which were originally in the grave-yard.
