The core part of the fundraising programme is focused on the cathedral's fabric. The major conservation-restoration projects already identified will cost £30 million. Fabric conservation is the most urgent element of the campaign. The appeal – the third of its kind following major fundraising drives at Canterbury in the 1950s and 1970s – was launched to fund these projects. Fundraising for the appeal will take place over a number of years both nationally and internationally, stressing the cathedral's role as the mother church of the worldwide Anglican Communion and as a World Heritage Site. An integrated conservation programme that addresses the priority areas has been drawn up by the cathedral's Surveyor to the Fabric, John Burton.
