WORK to return the final sections of a 600-year-old stained glass window to York Minster has started nearly a decade after over 300 panels were removed.

The Great East Window, regarded as one of the greatest artistic achievements of the Middle Ages, is the largest expanse of medieval stained glass in the UK. It depicts the beginning and end of all things from the Bible and is part of a £11.5m restoration project, at the Minster, which is due to be completed next year.

York Glaziers Trust removed all the glass in 2008 and over the past six years conservators have spent 92,400 hours meticulously restoring and conserving each piece.

Half the panels were returned two years ago and now the final 154 panels are being put back in. Sarah Brown, Director, said: “It’s a huge milestone to reach and exciting to think that, for the first time in nearly a decade, the Great East Window will again be complete."
