Port city (pop., 2001: city, 349,972; metro. area, 947,334), northern Spain. It is located 7 mi (11 km) inland from the Bay of Biscay. The largest city in the Basque Country, it originated as a settlement of mariners and ironworkers and was chartered in 1300. In the 18th century it prospered through trade with Spain's New World colonies. The city was sacked by French troops in the Peninsular War (1808) and besieged during the Carlist Wars (see Carlism). It is a chief port in Spain and a centre of the metallurgical industries, shipbuilding, and banking.
