The windows here are a mixture of late 19th and mid 20th century glass, much having been destroyed during the war. Clayton and Bell re-glazed the Chapter House in 1882 and in 1951 panels which survived the war were incorporated into a scheme drawn up by Joan Howson. The window over the entrance, showing sovereigns of England, was undamaged. Panels depict scenes from the history of England and the Abbey, with individual figures and coats of arms of kings, abbots, churchmen and benefactors to the Abbey.

In the vestibule of the Chapter House are lancet windows in memory of Lowell, poet and United States minister in London, unveiled in 1893. The coats of arms include those of the USA and Harvard university. The main figures are St Botolph, patron saint of Boston, the Pilgrim Fathers, St Martin and St Ambrose.

The subject of this small round window opposite the entrance to the Abbey Museum is St Francis and the birds. Designed by Francis Skeat and unveiled in 1988. Robinson Duckworth was Sub-Dean of the Abbey and a close friend of Lewis Carroll. He is buried in the choir of the abbey.
