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. == Construction == The dome is one of the largest of its type in the world. Externally, it appears as a large white marquee with twelve 100 m-high yellow support towers, one for each month of the year, or each hour of the clock face, representing the role played by Greenwich Mean Time. In plan view it is circular, 365 m (one metre for each day in a standard year) in diameter. It has become one of the United Kingdom's most recognisable landmarks. It can easily be seen on aerial photographs of London. Its exterior is reminiscent of the Dome of Discovery built for the Festival of Britain in 1951. The architect was Richard Rogers and the contractor was a joint venture company, McAlpine/Laing Joint Venture (MLJV) formed between Sir Robert McAlpine and Laing Management.〔(Millennium Dome site in £44m work bonanza ) Construction News, 28 May 1998〕 The building structure was engineered by Buro Happold, and the entire roof structure weighs less than the air contained within the building. Although referred to as a dome it is not strictly one as it is not self-supporting, but is in fact a giant Big Top, the canopy being supported by a dome-shaped cable network, from twelve king posts.〔(Long span structures ) Architecture Week, 26 March 2003〕 For this reason, it has been disparagingly referred to as the Millennium Tent. The twelve posts represent the twelve months of the year, another reference to time in its dimensions, alongside its height and diameter. The canopy is made of PTFE-coated glass fibre fabric, a durable and weather-resistant plastic, and is 52 m high in the middle – one metre for each week of the year. Its symmetry is interrupted by a hole through which a ventilation shaft from the Blackwall Tunnel rises. As with all tent canopies, the roof has a finite, weathering, life and once this is reached the decision will need to be made, either to replace it, at enormous cost, or to remove the entire structure. The critic Jonathan Meades has scathingly referred to the Millennium Dome as a "Museum of Toxic Waste",〔(【引用サイトリンク】title=Four Documentaries – Abroad Again in Britain )〕 and apart from the dome itself, the project included the reclamation of the entire Greenwich Peninsula. The land was previously derelict and contaminated by toxic sludge from East Greenwich Gas Works that operated from 1889 to 1985. The clean-up operation was seen by the then Deputy Prime Minister Michael Heseltine as an investment that would add a large area of useful land to the crowded capital. This was billed as part of a larger plan to regenerate a large, sparsely populated area to the east of London and south of the River Thames, an area initially called the East Thames Corridor but latterly marketed as the "Thames Gateway". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Millennium Dome」の詳細全文を読む スポンサード リンク
