Cambridge University's wealthiest college is putting the long-term lease of London's O2 arena up for sale.
Sky News has learnt that Trinity College has instructed property advisers to begin sounding out prospective investors about a deal.
Trinity, which ranks among Britain's biggest landowners, acquired the site in 2009 for a reported £24m.
The O2, which shrugged off its 'white elephant' status in the aftermath of its disastrous debut in 2000, has since become one of the world's leading entertainment venues.
Operated by Anschutz Entertainment Group, it has played host to a wide array of music, theatrical and sporting events over nearly a quarter of a century.
The opportunity to acquire the 999-year lease is likely to appeal to long-term income investment funds, with real estate funds saying they expected it to fetch tens of millions of pounds.
Trinity College bought the lease from Lend Lease and Quintain, the property companies which had taken control of the Millennium Dome site in 2002 for nothing.
The college was founded by Henry VIII in 1546 and has amassed a vast property portfolio.
It was unclear on Friday why it had decided to call in advisers at this point to undertake a sale process.
Trinity College Cambridge did not respond to two requests for comment.
