After a year travelling the world Britain's oldest surviving stained glass has returned home and is going on display at Canterbury Cathedral, so visitors can see it up close for the first time in an exhibition called The Ancestors.
The glass had been in the Cathedral's Great South window but had to be taken out when the stone frame began to crumble.
It will be on show for a limited time - before being returned to its rightful place next year. So you will never have the chance to get this close again.
Sarah Saunders spoke to Leonie Seliger, Director of the Cathedral's stained glass studio and The Very Reverend Dr Robert Willis, Dean of Canterbury.
