Stained glass like this can be seen in parish churches across the county of Norfolk.
Stained glass reflects the centrality of religion to medieval life. Wealthy donors paid for artworks to be put into churches; for the glory of God and to remind their contemporaries to pray for them.
East Anglia was very wealthy during the middle ages and Norwich was Britain's second city. The quality of the craftsmanship is very high. Norwich glass is celebrated for its delicately painted faces. Look at the angel's head in the centre of the middle panel.
The glass in this window comes from different parts of the church of St Peter Hungate. It was brought together into one window in 1907 to avoid destruction.
