Inside Out looks at a treasure trove of Viking objects as part of the BBC's History of the World project.
In January 2007 David and Andrew Whelan found a buried Viking horde in a field when they were metal detecting near Harrogate.
They took it to their local archaeological finds office before it was moved to the British Museum for conservation work.
The British Museum examined the cache to reveal 617 gold coins, jewellery, a silver and gold cup, and many other objects that revealed the scale and scope of the Viking world in North Yorkshire.
It is thought that the treasure was buried around AD927 by a Viking fleeing an attack, presumably with the intention of coming back to reclaim it.
Conservation work is now complete and the treasure trove will be the centrepiece exhibit when the Yorkshire Museum reopens following a major refurbishment in August 2010.
