The centre recently underwent a £4.5m extension and upgrade
A team of judges has visited a Denbighshire craft centre to decide if it is worthy of the art world's biggest single cash prize, of £100,000.
Ruthin Craft Centre is one of 10 UK venues long-listed for the Art Fund Prize for Museums and Galleries 2009.
The three judges will decide if it is to be shortlisted ahead of the final announcement on 18 June.
The Art Fund has already described it as "the most important gallery for contemporary craft in Wales".
The centre recently underwent a £4.5m extension and upgrade with new galleries, studios and an education suite.
The prize is awarded to the museum or gallery whose project "demonstrates the most originality, imagination and excellence".
It is the second year that the Art Fund charity has sponsored the prize.
David Barrie, Art Fund director, said: "All the long listed museums and galleries have shown exceptional creativity and ambition.
"They have made excellent use of new technology, architecture and innovative displays to enable their visitors to get the most out of their collections and exhibitions."
Three members of the judging panel including Sir Robert Crawford CBE, former director general of the Imperial War Museum, Turner Prize-winning artist Grayson Perry and Art Fund trustee Sally Osman visited the gallery on Wednesday.

Asked what he and the other judges were looking for, artist Grayson Perry said: "I'm a bit allergic to innovation because I think most things have been done.
"I look for the quality and the look of things, how beautiful they are and how well done they are and this place goes pretty well."
He said he had been a "bit worried" that the centre looked "industrial" in the pictures he had seen but added that it looked "much nicer in the flesh".
Centre director Philip Hughes said winning the prize would enable the centre to work closely with the town through projects in the community.
He said it would also enable the centre to generate more money through match funding.

He added: "This is a very strong competition and it's very flattering to be on such an interesting list.
"There are some amazing places on the list and the majority of them are far bigger than Ruthin Craft Centre with far more funding and staff."
Visitor Jan Hore from Chester said the centre would be a very "worthy winner".
Her husband Richard, an artist, said: "It's a brilliant gallery. We're very lucky to have something like this in the north west. It's excellent, there's no other word for it."
Another visitor Olive Jones from Greenfield, Holywell, Flintshire said: "I think it's very nice. The talent of the artists really stands out."
