With almost 2,500 pieces, measuring 30 metres and weighing 25 tonnes, it has been called the world’s largest 3D puzzle.
Archaeologists can now, after 20 years of painstaking restoration, start to reassemble the wreck of a 15th Century ship found in a south Wales riverbank.
Experts believe the medieval vessel is as significant a find as the Mary Rose – and it is a century older.
“The ship is of global significance and interest,” said TV historian Dan Snow.
Specialists have been working on the Newport Ship conservation project since the discovery of almost a third of the former wine- trading vessel and 1,000 medieval artefacts in the banks of the River Usk in 2002.
They have reached an important milestone on Thursday as all of its timbers, which had been preserved for more than 550 years, have now dried out and restored ready to go on display.
