a central
tower, and choir, beyond which is the retro-choir, or so-called Lady
Chapel. The nave and choir have aisles, but the transepts have not.
While strict orientation has been secured in the main building, it
will be noticed that the chancel is slightly deflected towards the
south, in supposed mystic allusion to the drooping head of the Saviour
upon the Cross, a piece of symbolism very frequent in Gothic churches,
and here rendered peculiarly appropriate by the dedication.[14]

Starting our perambulation at the =East End=, it will be noticed that
the so-called Lady Chapel is actually an enlargement of the choir,
such as we find on a much grander scale at Durham or Fountains, and
may be compared to the "Presbytery" at Chichester, from which the Lady
Chapel projects, or to the "New Building" at Peterborough Cathedral.
This addition was made to the church by Peter de Rupibus in the
thirteenth century, as a retro-choir or ambulatory. It was carefully
restored by Mr. George Gwilt, in 1832, from much external mutilation
to something like its original state. The eastern side consists of
four bays, divided by buttresses, and surmounted by pointed gables,
with ornamental crosses on the apices. In each of the gables there is
a triplet of narrow lancet windows, which light the space between the
internal vault and the roof. They have sculptured heads in the
moulding above the central light in each triplet. The bays below are
lighted by a similar series of larger windows of simpler
construction, the moulding of the sides being carried over the lancet
points in unbroken continuity. In the north-east corner there is a
short hexagonal stair turret, but the opposite corner is simply
supported by ordinary buttresses. The walls are made up of rubble and
flints, with ashlar dressing, as is supposed to have been the case
throughout the original church, where, however, the flints are said to
have been squared. In the reign of Edward III, a small Lady Chapel was
built against the east end of this retro-choir: it projected from the
second bay from the south, where the window was removed to connect it
with the church. After the interment of Bishop Andrewes within it,
this little appendage became popularly known as the "Bishop's Chapel."
It was demolished in 1830, on the ground of its supposed interference
with the approach to the new London Bridge; but as it only projected
thirty-four feet (a distance which would have placed it well within
