In the latter half of the fifteenth century great changes took place in the fabric of the priory church at Great Malvern, and by the beginning of the sixteenth century it had been transformed from what was largely, if not entirely, a Norman church to one of Perpendicular character. With the exception of a doorway on the south side of the nave, the nave arcade, and the bases of the piers that support the central tower, there are no evidences of work prior to the alteration. To this rebuilding both Richard III. and Henry VII. are said to have contributed, the west window of the nave is said to have been the gift of the former and the north window of the transept that of the latter, besides a very long list of benefactors, members of well-known families of the day, local and otherwise; and it is therefore not surprising that even in its present comparatively mutilated state the decorative work in this church is among the finest in England of its date, and the glass and encaustic tiles practically unsurpassed for beauty and interest.
