Adjoining this house, at the south-west corner, next the garden, stands a building generally known as "+Prior Crauden's Chapel+," having been founded by John de Crauden, prior of Ely (1321-1341), as a private chapel attached to his residence, and built under the direction of Alan de Walsingham, the skilful architect of the Octagon. It is most interesting for the rich remains of architectural beauty which it displays. "It is," says Mr. Rickman, "one of the most curious and valuable Decorated remains in the kingdom; its ornaments are of the best character, and well executed, and the whole design is of great excellence." It belongs to the Deanery, but was for many years used in connection with the adjoining house, having been converted into three rooms by floors inserted; these floors have been removed, and the chapel in some degree restored; some of the windows which had been closed have been re-opened, and the eastern one filled with stained glass, the gift of Mrs. Smart. It is now used as a private chapel for the Grammar School. The Chapel stands upon a vault, the floor of which is nearly upon a level with the surrounding ground; the vault has a groined ceiling supported by plain columns, and the original entrance was directly under the west window of the Chapel, but is now on the north side. The entrance to the chapel is by a staircase which winds within the buttress at the north-west angle. The length is divided into four compartments by clustered columns, from the tops of which sprung the ribs of the vaulting. The first compartment is plain, and was probably the ante-chapel: the second is ornamented with a double niche, richly decorated with small columns, pinnacles, crockets, &c.; in the lower niche the wall is pierced for a small window; the upper one probably contained a figure: the third and fourth compartments have long pointed windows, separated into two lights by a mullion. The east end has ornamented niches in the angles, it projects a little beyond the compartments, forming a recess, in which is the large window, divided into five lights, with elaborate tracery. The floor is elevated at the east end for the altar, and is formed of mosaic tiles; upon the raised portion is represented the Fall of man, and the remainder is ornamented with various other figures and devices; some portions are nearly perfect, but the colouring is greatly faded. Some remains of fresco painting were discovered on the walls when the restorations were in progress, and probably the chapel had originally been richly embellished with colours and gilding, in the style of the period in which it was built. We have now an opportunity of glancing at some of the other portions of the monastic buildings, which formerly extended from the Prior's Lodge to the gateway, but are now somewhat short of it, as a garden intervenes.
