context_page_description: Biscay is a province of Spain, lying on the south shore of the eponymous bay. The name also refers to a historical territory of the Basque Country, heir of the ancient Lordship of Biscay. Its capital city is Bilbao. It is one of the most prosperous and important provinces of Spain as a result of the massive industrialization in the last years of the 19th century and first half of the 20th century. Since the deep deindustrialization of the 1970s, the economy has come to rely more on the services sector.
context_section_description: The main geographical features of the province are:
  The southern high mountain ranges, part of the Basque mountains, that form a continuous barrier with passes not lower than 600 m AMSL, forming the water divide of the Atlantic and Mediterranean basins. These ranges are divided from west to east in Ordunte (Zalama, 1390 m), Salbada (1100 m),  Gorbea (1481 m) and Urkiola (Anboto, 1331 m).
  The middle section which is occupied by the main river's valleys: Nervion, Ibaizabal and Kadagua. Kadagua runs west to east from Ordunte, Nervion south to north from Orduña and Ibaizabal east to west from Urkiola. Arratia river runs northwards from Gorbea and joins Ibaizabal. Each valley is separated by medium mountains like Ganekogorta (998m). Other mountains, like Oiz, separate the main valleys from the northern valleys. The northern rivers are: Artibai, Lea, Oka and Butron.
  The coast: the main features are the estuary of Bilbao where the main rivers meet the sea and the estuary of Gernika (Urdaibai). The coast is usually high, with cliffs and small inlets and coves.
