what is the diameter of the millennium dome
Millennium Dome The dome is one of the largest of its type in the world.[2] 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.
Louvre Pyramid Commissioned by the President of France, François Mitterrand, in 1984, it was designed by the architect I. M. Pei. The structure, which was constructed entirely with glass segments and metal poles, reaches a height of 21.6 metres (71 ft).[2] Its square base has sides of 34 metres (112 ft) and a base surface area of 1,000 square metres (11,000 sq ft).[3] It consists of 603 rhombus-shaped and 70 triangular glass segments.[2] The pyramid structure was engineered by Nicolet Chartrand Knoll Ltd. of Montreal (Pyramid Structure / Design Consultant) and Rice Francis Ritchie of Paris (Pyramid Structure / Construction Phase).[4]
