Collect your car upon arrival at the airport. Explore Bilbao. Although the capital of the autonomous region of Euskadi – also known as the Basque Country – is Vitoria, the port city of Bilbao is, in fact, the largest of all Basque cities. The renewal of this industrial city has been continuous since the opening of the Guggenheim Museum in 1997, with various projects designed by famous architects, including a new tram system, a subway system designed by Sir Norman Foster, a pedestrian bridge, the Zubizuri bridge by Santiago Calatrava, a jagged glass-fronted public health building, and the reconversion following the indications of well-known designer Philippe Starck of a disused warehouse turned into a public multifunction building, the Alhóndiga.
