Coventry Cathedral's medieval stained glass windows, shattered and stored for decades, are now being rediscovered through a groundbreaking digital cataloguing project. The fragments, packed into 30 wooden crates after the cathedral was destroyed by the Luftwaffe in 1940, have been photographed and made accessible online for the first time in almost 90 years.
The collection, attributed to master glazier John Thornton of Coventry, includes biblical scenes, crucifixion imagery, donor portraits, whimsical animals, and representations of precious gems and jewelled fabrics. According to stained glass conservator Laura Atkinson, who led the cataloguing effort, the quality of the artwork is "stunning."
What Happened to Coventry Cathedral's Stained Glass?
The story of Coventry Cathedral's stained glass is one of destruction and survival. The windows were first smashed during the Reformation, then dismantled for safekeeping before World War II. When the cathedral was destroyed in 1940, the surviving fragments were gathered and stored in crates.
For decades, the cathedral authorities knew the remnants contained a treasure trove of 15th-century glass but were unsure exactly what had survived five turbulent centuries. The recent project to photograph and catalogue thousands of pieces has finally unlocked that mystery.
Why This Collection Is Internationally Significant
The glass is attributed to John Thornton of Coventry, a master glazier who also created the Great East Window of York Minster. Thornton's work is celebrated for its intricate detail and vibrant storytelling, and the Coventry fragments offer a rare glimpse into his craft.

Laura Atkinson describes the pieces as including "biblical scenes, crucifixion scenes" and "representations of the donors who funded the windows originally and are pictured kneeling and praying." Other fragments show "whimsical animals and beasts that are absolutely amazing" and depictions of precious gems and jewelled fabrics that required immense technical skill.
How Digital Access Brings the Glass Back to Life
The digital catalogue allows people in Coventry and around the world to view the collection virtually. This accessibility is particularly valuable given the fragile state of the glass, which cannot be easily displayed or handled.
By making high-quality images available online, the project ensures that the artistry of Coventry's medieval glaziers can be studied and appreciated by researchers, historians, and the general public alike.

What the Fragments Reveal About Medieval Craftsmanship
The surviving pieces showcase a range of subjects and techniques. Donor portraits, for example, provide insight into the individuals who funded the windows and their social status. The depiction of jewelled fabrics and precious gems highlights the glaziers' ability to imitate luxury materials using glass.
According to Atkinson, these representations required "immense technical" skill, underscoring the sophistication of medieval stained glass production. The whimsical animals add a playful dimension, suggesting a sense of humor or symbolic meaning that modern viewers can still appreciate.
