Work has begun to reinstall the historic Herkenrode Glass at Lichfield Cathedral.
Preparation for the main element of the project has started, with scaffolding due to be installed before the glass returns in November.
The Herkenrode Glass has been housed in Lichfield since 1803 after it was rescued from destruction during the Napoleonic Wars.
Despite having survived religious and political upheavals and a journey to England, the glass came under threat following centuries of weathering and pollution, as well as structural issues in the Lady Chapel.
Emergency action was taken and the race began to save the East End and its Renaissance glass, which was removed in 2010 and taken to Barley Studios where the conservation project began.
The Very Revd Adrian Dorber, Dean of Lichfield, says: “The return of the Herkenrode Glass is a monumental event at the Cathedral.
“We have raised all but £60,000 of our £3.7million target in order to repair and conserve the glass, as well as repair and renew the stonework in the Lady Chapel.
“I’d like to say a warm ‘thank you’ to those who have contributed so generously to the East End Appeal. If you would still like to support the campaign, you can do so through our Give a Lasting Gift scheme.”
A series of celebratory events will take place at the Cathedral once the work is completed in March 2015.
