The St William Window c1414
The St William window in the north-east transept, made c1414, was probably designed and made by the workshop of John Thornton, best known as the author of the Minster's Great East Window.
Undertaken between 1998 and 2008, the conservation of the St William window has been one of the most ambitious projects ever worked on by the York Glaziers Trust. The window was last restored in 1895 and having been unprotected on the exposed north side of the building, required re-leading in order to stabilize it for the future.
Dismantling allowed in-depth research of the panels, the removal of many mending leads and some restoration glass-painting. The work has transformed the legibility of this great story window dedicated to York Minster's resident Saint, William Fitzherbert (died 1154, canonized 1227).
