974 fragments of medieval window glass were recovered during the excavations of St. Saviour’s Hospital in Bury St Edmunds.
Many of the fragments were decorated with floral patterns or inscriptions. The window glass has been coloured in two ways: staining or painting. There are a large variety of colours including: blue, green, ruby and yellow. There are five main categories of designs represented in the window shards: foliate, architectural, geometric, figurative and inscriptions. A staggering 166 different unique designs have been identified across all five of the categories listed above. Many of these designs can be seen in stained windows across Norfolk, but amazingly some have also been spotted at Cantebury Cathedral.

It is unknown how many stained glass windows there were at St. Saviours Hospital, as only the setting for the ‘West Window’ still survives in the ruins today. It is suggested in historical sources that the ‘West Window’ may have also been known as the ‘Great Hospital Window’. The ‘Great Hospital Window’ almost certainly contained decorated glass and was even fitted with shutters:
“In 1385-6 a shutter with twigs was bought for the great window in the hospital for 6d”
The variety in the fragments here suggest that there were other stained glass windows, as the evidence shows varying quality and thickness of the glass, the different inscription designs and a 50 year gap in the dates of some of the glass fragments which range from the Late 1300’s to the Early 1400’s.
Sadly the chapel and hospital were dissolved along with the Abbey in 1539 and was later at least partially demolished. A small section of the ruins are still standing alongside the rear car-park of the large Tesco supermarket on the St. Saviours interchange.
