Bilbao is the heart of a metropolis where more than a million people live. It is the centre of the economic-social development and the main factor of the modernisation of the Bay of Biscay. The great architectural and infrastructure projects have been the driving force of the urban and economic regeneration of the city. The Bilbao Guggenheim Museum, the Euskalduna Conference and Music Centre, Norman Foster's Underground, Calatrava's airport, the towers designed by the architects Arata Isozaki and César Pelli... are all examples of the dynamism that exists in Bilbao. The city is situated in the area of Bizkaia and is surrounded by a fertile landscape with forests, mountains, beaches and steep coasts. All this makes Bilbao a privileged destination for visitors. The modern transport and network of roads run to locations nearby such as the other capitals of the Basque Country - Vitoria and San Sebastián.
