The Evoluon is a conference centre and former science museum erected by the electronics and electrical company Philips at Eindhoven in the Netherlands in 1966. Since its construction, it has become a landmark and a symbol for the city. Its concrete dome is 77 metres (253 ft) in diameter and is held in place by 169 kilometres (105 mi) of reinforcing steel bars. In the UK the Evoluon is chiefly remembered from Bert Haanstra's wordless short film entitled simply Evoluon, commissioned by Philips to publicise the museum, and shown as a trade test colour film on BBC television from 1968 to 1972. * *
