York Minster holds the largest collection of medieval stained glass in the country, with 128 windows dating back to the 12th century.
Currently 60% of the cathedral's windows have no protective glazing, leaving them exposed to the elements and subject to corrosion and decay, meaning the irreplaceable glass could be lost for future generations.
To halt the decay, the cathedral has announced a 20-year partnership with York Glaziers Trust and an innovative fundraising campaign led by the York Minster Fund, supported by a £1m grant from the Heritage Lottery Fund.
The initiative, which will cost £11m to complete, will see state-of-the-art, environmental protective glazing extended to all of the Minster's 128 windows as part of a long-term strategy to buy time for much needed conservation work.
The work will be funded in part by the Heritage Lottery Stained Glass Endowment Fund, which will involve a four year campaign where every £1 donated by the public will be matched by both the YMF and HLF, up to £1m.
This means that if a member of the public donates £1 and opts to include Gift Aid, £5 will go into the endowment fund. The money will then be invested and the returns from the fund used to pay for the ongoing conservation work.
