It's the most famous landmark in the South East - attracting almost a million tourists a year. Now Canterbury Cathedral is undergoing its biggest restoration ever.
The conservation scheme called 'The Canterbury Journey' is costing close to £25million. A painstaking process mixing engineering with a place of quiet daily worship.
The first step - an enormous scaffolding built inside the cathedral - is now almost finished and offers stunning views of the building itself.
Andy Dickenson went to take a look and spoke to site manager Matthew Butler, head of conservation Heather Newton and Mark Hosea, project director.
