Biscay is a province in northern Spain located along the southern shore of the Bay of Biscay. In the Basque language it is known as Bizkaia, and in Spanish as Vizcaya. The area also corresponds to a historic territorial unit within the Basque Country. Its administrative capital and largest city is Bilbao, a major port and economic centre. Biscay forms one of the provinces that make up the autonomous Basque Community and is officially a province of Spain.

Geography

Biscay occupies a coastal strip and a series of inland valleys and foothills that rise toward the Cantabrian Mountains. Its shoreline faces the open waters of the Bay of Biscay, which has shaped the province's maritime economy and climate. The landscape combines urbanized basins around Bilbao with rural and wooded highlands farther from the coast.

Administration and population

The province functions as one of the administrative provinces within Spain and as a historical territory of the Basque Autonomous Community. Bilbao serves as the seat of provincial institutions and is the region's principal population and business centre. Municipal governments administer local services across the province's towns and smaller cities.

Language and names

Both Basque and Spanish are spoken in Biscay; place names are commonly encountered in both languages. The Basque name, Bizkaia, and the Spanish name, Vizcaya, are used in official and everyday contexts. English-language references often use the traditional name "Biscay."

History and culture

Biscay has a distinct identity within the Basque Country that reflects its medieval institutions, maritime traditions and industrial development. Over time the province became a centre for shipbuilding, trade and later heavy industry, particularly around Bilbao. Cultural life mixes Basque-language traditions with wider Spanish influences.

Economy

The province's economy combines port activities, industry and services. Bilbao's port and transport links play a central role, while tourism and cultural projects have been important for urban renewal. Agriculture and forestry remain significant in rural areas of the province.
