High Quality Content by WIKIPEDIA articles! The Millennium Dome, colloquially referred to simply as The Dome, is the original name of a large dome-shaped building, originally used to house the Millennium Experience, a major exhibition celebrating the beginning of the third millennium. Located on the Greenwich Peninsula in South East London, England, the exhibition was open to the public from 1 January to 31 December 2000. The project and exhibition was the subject of considerable political controversy as it failed to attract the number of visitors anticipated, with recurring financial problems. All of the original exhibition and associated complex has since been demolished. The dome still exists, and it is now a key exterior feature of The O2. The Prime Meridian passes the western edge of the Dome and the nearest London Underground station is North Greenwich on the Jubilee Line.
