Is the National Library of Wales' cup the Holy Grail?
A religious relic which, claimed by some to be the Holy Grail, is to go on permanent display at the National Library of Wales.
The fragile piece of wood is all that remains of the Nanteos Cup, a wooden chalice named after the mansion in Aberystwyth where it was once kept.
Some believe it was the cup from which Christ drank at the Last Supper and that it has healing powers.
It was stolen in 2014 before being returned to its owners a year later.
Pedr ap Llwyd, director of collections and public programmes at the library, said visitors would finally be able to view the "mysterious object".
