As part of the 900th anniversary celebration of Abbot Serlo laying the foundation stone of St Peter’s Abbey (now Gloucester Cathedral) in 1089, the South Ambulatory Chapel was refitted with a new stained glass window by Thomas Denny.
Depicting the New Testament story of Thomas in the presence of the risen Christ in the centre light, the windows either side are based on Psalm 148, praising God’s creation. The triptych illuminates the chapel in a magnificent blue light.
