wall arcade having single
pointed arches, with first pointed mouldings. The windows over the
arcade correspond generally to those in the north wall, and are all
pointed except the two east bays already mentioned. The lower part
of the exterior of the south wall, running westward from the Norman
doorway, is arcaded with a series of large pointed arches, each
enclosing five smaller pointed arches, and with a plain wall space
between the large and small arches. The above large arches were the
wall arches for a groined roof over the cloister walk, but whether
that vault was ever built it is now regarded as impossible to say.
The vaulting of both aisles has apparently been similar, but the
south aisle alone retains it, which is of a simple character,
consisting of transverse and diagonal ribs.

The main arcade of the nave has consisted of eight bays; the
triforium is divided into two arches in each bay by a single central
shaft, springing from a corbel over the apex of each arch of the
main arcade, and running up to the string-course beneath the
clerestory. This would suggest the view that the vaulting was
sex-partite. Each arch of the triforium is acutely pointed, and
contains two smaller pointed arches within it, each of which has an
inner trefoiled arch. The tympanum of the large arch is pierced
with a quatrefoil or trefoil. To counteract the weakening tendency
of the triforium passage, saving arches, as may be seen from the
south, have been introduced to carry the chief pressure across from
main pier to main pier. A similar strengthening arch exists in the
outer wall of the triforium gallery at Amiens. The west end is
pronounced to have contained the finest work of the building, and
the west door with the two towers must have presented a lovely and
imposing front. The S.W. tower was removed to make way for the
palace being erected, and even the W. doorway is encroached on by
the palace wall. A portion of the S.W. tower is still visible in the
interior, and contains a doorway. The upper part of the W. end was
reconstructed by Charles I. in 1633, and contains two nondescript
windows of seventeenth century Gothic with an inscription between
them. The tympanum of the doorway has also been altered at this
time, and an oaken lintel introduced containing a shield with the
initials of C
