In partnership with Westminster City Council, the Russian organisers of the next Winter Games will "introduce the southern Russian city of Sochi and the surrounding Krasnodar Region through sport and cultural performances".
The move will see Marble Arch transformed into an ice rink, complete with stands and is expected to be self-funded through ticket sales.
"The public activities will run under the name of Sochi World and will focus on master-classes and spectacular shows on an ice-rink," said CEO and president of Sochi 2014 Dmitry Chernyshenko. "The aim will be to present a new feature of the Sochi Games by reflecting the many different aspects of Russian culture across all its regions."
Alongside the ice-rink arena, set in front of the Marble Arch monument, "Sochi World" will include an interactive visitor experience.
Update: Although Sochi showed its ambitious plans to a room full of media on Thursday, Westminster Council has yet to clear the project and it could yet fail to receive planning permission.
"We are looking forward to welcoming the world to London in 2012 and are determined to play our part in hosting and celebrating the Games," said Westminster City Council’s Deputy Leader and Cabinet Member for the Built Environment Robert Davis.
"We expect a planning application from Sochi shortly, and this will be assessed by our planning team in due course."
