The exterior of the chapel is distinguished by the richness and variety of its form, occasioned chiefly by 14 towers, elegantly proportioned to the body of the edifice, and projecting in different angles from the outer-most wall: the inside is approached by the area at the back of the chapels of Edward the Confessor and Henry v.

The floor of this chapel is elevated above that of the area, and the ascent is by a flight of marble steps: the entrance is ornamented with a handsome gothic portico of stone, within which are three large gates of gilt brass, of curious open workmanship, every pannel being enriched with a rose and a portcullis alternately.

The chapel consists of the nave and two small aisles: the centre is 99 feet in length, 66 in breadth, and 54 in height, terminating at the east in a curve, and having five deep recesses of a similar form: the entrance to these recesses is by open arches, and they add greatly to the relief and beauty of the building: it is not improbable that they were originally so many smaller chapels, destined to various uses.

The side aisles are in a just proportion to the centre, with which they communicate by four arches, turned on gothic pillars; each of them is relieved by four recesses, a window, with minute and curious ~85~~divisions, running the whole height of each recess.

The upper part of the nave has four windows on each side, and ten in the eastern extremity, five above and five below.
