Millennium Dome

The Millennium Dome was the original name of the large dome-shaped building on the Greenwich Peninsula in South East London, England, which housed a major exhibition celebrating the beginning of the third millennium. When opened in 1999, it was the fifth largest building in the world by usable volume. The exhibition was open to the public from 1 January to 31 December 2000. The project and exhibition were highly contentious and attracted barely half of the 12 million customers its sponsors forecasted, and so were deemed a failure by the press. All the original exhibition elements were sold or dismantled. In a 2005 report, the cost of the Dome and surrounding land (which increased to 170 acres from the initial offering of the 48 acres enclosed by the Dome) and managing the Dome until the deal was closed was £28.7 million. The value of the 48 acres occupied by the Dome was estimated at £48 million, which could have been realised by demolishing the structure, but it was considered preferable to preserve the Dome. The structure itself still exists and serves as the exterior to The O2 entertainment complex, which includes the O2 Arena. The Prime Meridian passes the western edge of the Dome and the nearest London Underground station is North Greenwich on the Jubilee line.
