1361, the wooden spire and parts of
central tower of the cathedral were blown down by a violent gale of
wind, and the presbytery was greatly damaged by the falling material.
This bishop rebuilt the present clerestory, designed in the transitional
style between Decorated and Perpendicular; the vault is later. It is
also probable that he repaired the spire.

During Bishop Wakering's time the Erpingham gate of the close was
erected, and as well the cloister that formerly connected the palace on
the north side with the cathedral. He also founded a chantry for one
monk at his tomb.

His successor, Alnwick, completed the cloisters. The gateway to the
palace was built by him about 1430, and probably replaced an earlier
structure. He also began the work of remodelling the central compartment
of the west front. He left directions in his will to his executors to
make a large west window, the cost to be charged to his estate. The
doorway under this window, built over the old Norman one, and
encroaching on the side arcading, was executed during his episcopate,
the window being eventually added during the time of Bishop Lyhart to
throw additional light on to the vault he erected, and its wonderful
sculptures.

In 1446, on February 27th, Walter Lyhart, or le Hart, was consecrated,
and it is to him that Norwich Cathedral owes the superb _lierne_ vault
that now spans the nave. Other important works were carried out by him;
the spire which had been blown down in 1362 (and had probably been
re-constructed by Bishop Percy--though there is no record of such work),
was struck by lightning in 1463, and the burning mass fell through the
presbytery roof, which up till this period was still in wood, completely
destroying it, and making necessary the vault added by Lyhart's
successor.

During this episcopate the rood screen was erected, and a sumptuous
monument placed over the grave of the founder.

The stone spire must have been added about this time, replacing the
former wooden construction.

Bishop Lyhart left to his successor, Bishop Goldwell, in his will 2200
marks for repairing the dilapidations caused by the fire of 1463. During
this bishop's episcopate we find that the cathedral was brought nearly
to that state in which we have it now,--the tower was still further
adorned with Perpendicular battlements, the presbytery was vaulted in
with stone, and the flying-buttresses added around the eastern apse to
take the consequent thrust
