The four windows in the St John Chantry are by highly regarded Victorian stained glass firms. From east to west (moving away from the organ) they are:

Faith, Hope and Charity – Heaton & Butler (1869)
– in memory of Caroline Bartrum, wife of Edward Bartrum, Headmaster of the school 1864-1889. Caroline is shown in the top quatrefoil with her young children, representing Charity.

The Sower & the Good Shepherd – Heaton & Butler (1865)
– in memory of John Crawford, Headmaster of the school 1850-1864. Israel’s King David is shown in the top quatrefoil.
The last two windows both depict the Annunciation; there is a clear contrast of styles that reflects the 27 years that separate them.

Curtis, Ward & Hughes (1901)
in memory of Adelaide Frances Darroch

Clayton & Bell (1874)
in memory of Mary Cooper, wife of William Cooper (William is commemorated in a window in the north aisle)
