Millenium Dome

The Mill­en­nium Dome takes place on a 181-acre site on the North Green­wich pen­in­sula boun­ded on three sides by the River Tha­mes. Part of a 300-acre for­mer gas­works, it had been de­relict for more than two de­ca­des and was the lar­gest un­de­ve­l­o­ped site on the River Tha­mes.The Prime Me­ri­dian cuts across the north of the site which is about two and a half ki­lo­metres from his­to­ric Green­wich. The Mill­en­nium Dome has been de­si­gned by ar­chi­tects, The Ri­chard Ro­gers Part­nership in 1999. The Dome is 320 m in dia­me­ter and 50 m high at its centre. The fa­bric struc­ture is sus­pen­ded from twelve 100 m high steel masts, held on a net of more than 72 km of high strength steel cable.

The roof fa­bric is self-cleaning PTFE-coated glass fibre with a mi­ni­mum life of 25 years, which can be re­ne­wed in sec­tions if ne­cessary. A two-layer fa­bric pro­vi­des in­su­la­tion to prevent con­den­sa­tion.
