The large window by the pulpit dates back to the 15th century. It is a Perpendicular work, with square head and panelled tracery. This tracery contains the only fragments of medieval stained glass to have survived.

Prior to the Reformation most churches were alive with the colours of stained glass and wall paintings, as well as having statues and other imagery. It is hard to imagine the difference when we look at the blank walls and windows of today.

The motif of the stained glass is very similar to that in St John the Baptist church in Broad Street Bristol, above the hole in the wall.
