Bilbao straddles the Bilbao or Nervión River some 15 miles from the Cantabrian Seacoast. An industrial city, the metropolitan area ranks among Spain's most important commercial and financial centers. Proximity to the sea and early discovery of vast mineral deposits led to the development of the port. The modern city center is El Ensanche (literally "the expansion"). Possibly the newest source of great local pride is the remarkable Guggenheim Museum-Bilbao.
