Ely Cathedral — Lady Chapel and Processional Way Glazing Conservation
Ely Cathedral is one of the great surviving examples of Norman and Gothic architecture in England, a Grade I listed building of international significance whose Lady Chapel — begun in 1321 — represents the most elaborate English Decorated Gothic interior of its period. The Lady Chapel's glazing and the processional way glazing presented Barley Studio with one of their most complex historic glass conservation challenges: glass that had been subject to centuries of restoration, replacement, and deterioration, set in windows of exceptional architectural importance.
Barley Studio's conservation programme on the Ely glazing addressed the accumulated complexity of the windows' history: layers of different period restorations, glass of varying ages and conditions, and a patchwork of historic and replacement glass requiring careful assessment, documentation, and conservation treatment. The studio's minimum-intervention philosophy was applied throughout: stabilising rather than replacing wherever possible, reversing previous inappropriate interventions where necessary, and installing protective glazing to manage the ongoing environmental threat.
The processional way glazing presented additional challenges of access and logistics in an active cathedral environment. Barley Studio's PASMA and IPAF-certified team worked at height in the confined spaces of the processional way with the care and precision that the historic setting demanded. The completed programme has extended the life of the Ely glazing and provided the cathedral with a comprehensive condition record as the basis for its ongoing stewardship.
