Tony Blair’s Labour government were desperate to offload the £800 million structure built on the Greenwich peninsula, regarded at the time as a costly white elephant with the Millennium Experience only bringing in half the projected 12 million visitors.
But as they cast around for offers, they were presented with one particularly eye-catching proposition – uproot the whole thing from south-east London and move it 85 miles west to Wiltshire.
Papers released to the National Archives in Kew, west London, show that the scheme was the brainchild of the Science Museum’s director Lindsay Sharp.
In a letter to the prime minister, he suggested that it could be repurposed to house a new museum on an old military airfield at Wroughton on the outskirts of Swindon.
“I am writing to you about a completely different and exciting possibility for the Dome,” he enthused.
“This proposal presents a unique range of features at a time when such characteristics may, together, provide a unique solution to the challenges of the Dome.”
It could, he suggested, become home to “a major new public facility devoted to interactivity and immersively exhibiting the latest in practical aspects and research into sustainability” while freeing the valuable Greenwich site for redevelopment.
Mr Sharp cheerfully admitted that he did not know whether the plan – involving the relocation of a structure 365 metres (1,200ft) in diameter and 52 metres (170ft) high – was actually feasible.
“This is a ‘big concept’ approach and would need a rapid and detailed evaluation,” he wrote.
The idea failed however to catch the imagination of ministers.
In December 2001 it was announced that Meridian Delta Ltd had been chosen to develop the Dome as a sports and entertainment centre and in 2005 it was renamed The O2 arena.
Parts of the building’s roof was shredded on February 18, as the UK was battered by record-breaking Storm Eunice.
