The chancel is also Perpendicular in style, and contains the monument of John Knotsford (died 1589), who was one of those involved in the dissolution of the former monastic foundation. It is largely thanks to his patronage that the church, and particularly its medieval glass, survived so well. The north transept window, depicting the Coronation of St Mary, was donated to the priory by King Henry VII of England, and was designed by the royal glazier in 1501 - which helps to explain its survival.
