This pair of Perpendicular windows represent the completion of
the rectangle of the church building programme, probably by 1480.
The two windows are identical and have five lights with pointed
arches and cinquefoiled heads.
A full set of mullions form ten half-lights. The three which
reach towards the tops of the window arch or the sub-arches have
Y-endings.
The outer pairs of lights have sub-arches which are cut across
by crenellated transoms. A central third transom, of equal length,
rests at a higher level on the sub-arches.
The result of all this to create 23 spaces of various shapes and
sizes (plus six small triangles) which are cusped to form
quatrefoils or cinquefoils. The circle at the head of the window is
given an elaborate quatrefoil whose foils are themselves
trefoiled.
