The Bay of Biscay (Spanish: Golfo de Vizcaya; French: Golfe de Gascogne; Basque: Bizkaiko golkoa; Breton: Pleg-mor Gwascogn; Gascon: Golf de Gasconha) is a gulf of the northeast Atlantic Ocean located south of the Celtic Sea. It lies along the western coast of France from Brest south to the Spanish border, and the northern coast of Spain west to Cape Ortegal, and is named in English after the province of Biscay, in the Spanish Basque Country.

The average depth is 1,744 metres (5,722 ft) and maximum depth is 2,789 metres (9,150 ft).

Geography[link]

Parts of the continental shelf extend far into the bay, resulting in fairly shallow water in many areas and thus cause the rough seas for which the region is known. The Bay of Biscay is home to some of the Atlantic Ocean's fiercest weather. Large storms occur in the bay, especially during the winter months. Up until recent years it was a regular occurrence for merchant vessels to founder in Biscay storms, and many lives were lost. Improved ships and weather prediction have reduced the toll of the storms.

Extent[link]

The International Hydrographic Organization defines the limits of the Bay of Biscay as "a line joining Cap Ortegal (43°46′N 7°52′W / 43.767°N 7.867°W / 43.767; -7.867) to Penmarch Point (47°48′N 4°22′W / 47.8°N 4.367°W / 47.8; -4.367)".^[1]

Rivers[link]

The main rivers that empty into the Bay of Biscay are:

• France (north to south): Loire, Charente, Garonne, Dordogne, Adour, Nivelle.
• Spain (east to west): Bidasoa, Oiartzun, Urumea, Oria, Urola, Deba, Artibai, Oka, Nervión, Agüera, Asón, Miera, Pas, Saja, Nansa, Deva, Sella, Nalón, Navia, Esva, Eo, Landro, Sor.

Weather[link]

As in many west coasts^{[citation needed]}, the phenomenon of June Gloom is common. In late spring and early summer a large fog triangle fills the southwestern half of the bay, covering just a few kilometres inland.

As winter begins, weather becomes severe. Depressions enter from the west very frequently and they either bounce north to the British Isles or they enter the Ebro Valley, dry out, and are finally reborn in the form of powerful thunderstorms as they reach the Mediterranean Sea. These depressions cause severe weather at sea and bring light though very constant rain to its shores (known as orballo, sirimiri, morrina, orbayu and orpin (in Asturias) or calabobos in northern Spain). Sometimes powerful windstorms form if the pressure falls rapidly, traveling along the Gulf Stream at great speed, resembling a hurricane, and finally crashing in this bay with their maximum power, such as the Klaus storm.

The Gulf Stream enters the bay following the continental shelf's border anti-clockwise (the Rennell Current), keeping temperatures moderate all year long.

Main cities[link]

The main cities on the shores of the Bay of Biscay are:

• France: Brest, Nantes, La Rochelle, Bordeaux, Bayonne, Biarritz.
• Spain: Donostia-San Sebastián, Bilbao, Santander, Gijón, Avilés.

History[link]

The southern end of the gulf is also called in Spanish "Mar Cantábrico" (Cantabrian Sea), from the Estaca de Bares, as far as the mouth of Adour river, but this name is not generally used in English. It was named by Romans in the 1st century BC as Sinus Cantabrorum (Bay of the Cantabri), more frequently, Mare Gallaecum.

On some medieval maps, the Bay of Biscay is marked as El Mar del los Vascos (the Basque Sea). The Bay of Biscay is the birthplace of what is considered one of the world's most successful and most renowned maritime industries, the Basque and Cantabrian shipbuilders and fishermen.

Wildlife[link]

The coast of the Bay of Biscay – San Juan de Gaztelugatxe (Biscay)

The car ferries from Gijón to Nantes/Saint-Nazaire, Portsmouth to Bilbao and from Plymouth, Portsmouth and Poole to Santander provide one of the most convenient ways to see cetaceans in European waters, and there are often specialist trips on board. Volunteers and employees of Biscay Dolphin Research regularly observe and monitor cetacean activity from the bridge of the ships on the P&O Ferries Portsmouth to Bilbao route. Many species of whales and dolphins can be seen in this area but it is one of the few places where the beaked whales such as the Cuvier's beaked whale have been observed relatively frequently. This is the best study area for beaked whales in the world.

The best areas to see the larger cetaceans lie in the deep waters beyond the continental shelf, particularly over the Santander Canyon and Torrelavega Canyon in the south of the Bay.

The three-day round trip also gives sightings of good numbers of several species of seabirds, particularly gannets.

The alga Colpomenia peregrina was introduced and first noticed by oyster fishermen in the Bay of Biscay in 1906.

Biscay (in Basque and officially Bizkaia and in Spanish Vizcaya) is a province of Spain and a historical territory of the Basque Country, heir of the ancient Lord 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 of the last years of the 19th century and first half of the 20th century. Currently, the industrial activity has given away space to an important activity in the services sector, especially since the deep deindustrialization of the 1970s.

Etymology[link]

It is nowadays accepted in linguistics (Koldo Mitxelena, etc.) that Bizkaia, the original Basque term, is a cognate of bizkar (cf. Biscarrosse in Aquitaine), with both place-name variants well attested in the whole Basque Country and out^[1] meaning 'low ridge' or 'prominence' (Iheldo bizchaya attested in 1141 for the hill Igeldo in Donostia).^[2]

Denominations[link]

[edit] Bizkaia

“Bizkaia” is the Basque denomination recommended by the Royal Academy of the Basque language, and it is commonly used on official documents on that language. It is also used on documents in Spanish, and it is the most used denomination by the media in Spanish in the Basque Country. It is also the denomination used in the Basque version of the Spanish constitution and in the Basque version of the Statute of Autonomy of the Basque Country.

Bizkaia is also the only official denomination approved for the historical territory by the Juntas Generales of the province.

[edit] Vizcaya

“Vizcaya” is the denomination in Spanish, recommended by the Royal Spanish Academy. It is used in non-official documents and, in general, by Spanish speakers. It is also the Spanish denomination used in the Spanish version of the Constitution and in the Spanish version of the Statute of Autonomy of the Basque Country.

History[link]

Biscay has been inhabited since the Middle Paleolithic, as attested by the archaeological remains and cave paintings found in its many caves. The Roman presence had little impact in the region and the Basque language and traditions have survived to this day.

Biscay itself appears in the Middle Ages, as a dependency of the kingdom of Pampelune (XI cent.) that became autonomous and finally a part of the Crown of Castile. The first mention of the name Biscay is appearing in a donation act to the monastery of Bickaga, located on the ria of Mundaka. According to Anton Erkoreka,^[3] the Vikings had a commercial base there from which they were expelled by 825. The ria of Mundaka is a easiest way to the river Ebro and at the end of it, the mediterranean trade.

In the modern age, the province became a major commercial and industrial area. Its prime harbour of Bilbao soon became the main Castilian gateway to Europe. Later, in the 19th and 20th centuries, the abundance of prime quality iron ore and the lack of feudal castes favored rapid industrialization.

Paleolithic[link]

Some prehistoric cave sites in Biscay.

Middle Paleolithic[link]

The first evidence of human dwellings (Neanderthal people) in Biscay happens in this period of prehistory. Mousterian artifacts have been found in three sites in Biscay: Benta Laperra (Karrantza), Kurtzia (Getxo) and Murua (Durangoaldea).

Late Paleolithic[link]

• Chatelperronian culture (normally associated with Neanderthals as well) can be found in Santimamiñe cave (Busturialdea).

Most important settlements by modern humans (H. sapiens) can be considered the following:

• Aurignacian culture: Benta Laperra, Kurztia, and Lumentxa (Lekeitio)
• Gravettian culture: Santimamiñe, Bolinkoba (Durangoaldea) and Atxurra (Markina)
• Solutrean culture: Santimamiñe and Bolinkoba
• Magdalenian culture: Santimamiñe and Lumentxa

Paleolithic art is also present. Benta Laperra cave shows the oldest paintings, maybe from the Aurignacian or Solutrean period. Bison and bear are the animals depicted, together with abstract signs. From later periods (Magdalenian) are the murals of Arenaza (Sodupe) and Santimamiñe. In Arenaza female deers are the dominant motive, Santimamiñe shows bisons, horses, goats and deers.

Epi-paleolithic[link]

This period (also called Mesolithic sometimes) is dominated in Biscay by the Azilian culture. Tools become smaller and more refined and, while hunting remains, fishing and seafood gathering become more important, finding now clear evidence of wild fruits too. Again Santimamiñe is one of the most important sites of this period. Others are Arenaza, Atxeta (not far from Santimamiñe), Lumentxa and nearby Urtiaga and Santa Catalina, together with Bolinkoba and neighbour Silibranka.

Neolithic[link]

While the first evidences of Neolithic contact in the Basque Country can be dated to the 4th millennium BCE, it will be not until the beginning of the 3rd one that the area accepts, gradually and without radical changes, the agricultural and specially shepherding advances. Biscay is not particularly affected by this change and only three sites can be mentioned for this period: Arenaza, Santimamiñe and Kobeaga (Ea) and the advances adopted seem limited initially to sheep, domestic goats and very scarce pottery.

Together with Neolithic technologies, Megalithism also arrives. It will be the most common form of burial (simple dolmen) until c. 1500 BCE.

Chalcolithic and Bronze Age[link]

While open air settlement starts to become something common as population grows, caves and natural shelters are still used in Biscay in the Chalcolithic and Bronze Age. Hunting becomes gradually a less important source of meat, replaced by sheep, goats and some bovine cattle. Metallic tools become more common but stone-made ones are also used.

Pottery types shows great continuity (not decorated) until the bell beaker makes its appearance.

The sites of this period now cover all the territory of Biscay, many being open air settlements, but the most important caves of the Paleolithic are still in use as well.

Iron Age[link]

Very few sites have been identified for this period. Caves are abandoned for the most part but they still give some remains. The main caves of prehistory (Arenaza, Santimamiñe, Lumentxa) were still inhabited.

Roman period[link]

Forua archaeological site.

Roman geographers have let us know that the territory of what is now Biscay dwelt two tribes: Caristii and Autrigones. The Caristii dwelt in nuclear Biscay, east of the firth of Bilbao, extending also into Northern Araba and some areas of Gipuzkoa, up to the river Deba. The Autrigones dwelt in the westernmost part of Biscay and Araba, extending also into the provinces of Cantabria, Burgos and La Rioja. Based in toponimy, historical and archaeological evidence, it is thought that these tribes spoke Basque language [2]. The borders of the Biscayan dialect of Basque seem to be exactly those of the Caristian territory, exception made of the areas that have lost the old language.

There is no indication to resistance to Roman occupation in all the Basque area (excepting Aquitaine) until the late feudalizing period. Roman sources mention several towns in the area, Flaviobriga and Portus Amanus, though they have not been located. The site of Forua, near Gernika, has yielded archaeological evidence of Roman presence [3].

In the late Roman period, together with the rest of the Basque Country, it seems to have revolted against Roman domination and the process of feudalization.

Middle Ages[link]

In the Early Middle Ages, the history of Biscay cannot be separated from that of the Basque Country as a whole. The area was de facto independent although Visigoths and Franks attempted to stabilish their domination from time to time. Encounters between the Visigoths and Basques usually led to defeat for the latter and the Visigoths managed to establish an outlying post at the later city of Vitoria to counter incursions and the migration of basques from the coastal regions to the north.

In 905, Leonese chronicles mention the Kingdom of Pamplona as including all the western Basque provinces, as well as the Rioja region for the first time. The territories that would later constitute Biscay were then part of that state.

In the conflicts that the newly sovereign Kingdom of Castile and Pamplona/Navarre had in the 11th and 12th century, the Castilians were supported by many landowners from La Rioja, who sought to consolidate their holdings under Castilian feudal law. These pro-Castilian lords were led by the house of Haro, who were eventually granted the rule of newly created Biscay, initially made up of the valleys of Uribe, Busturia, Markina, Zornotza and Arratia, plus several towns and the city of Urduina. It is unclear when this happened exactly but it is claimed that Iñigo López was the first Lord of Biscay in 1043.^{[citation needed]}

The region soon reverted to Navarre, remaining so until the Castilian invasion of 1199-1200.

The title to the lordship was inherited by Iñigo López's descendants until, by inheritance, in 1370 it passed to John I of Castile, becoming one of the titles of the king of Castile. Since then it remained connected to the crown, first to that of Castile and then, from Carlos I, to that of Spain, always with the condition that the Lord swore to defend and to maintain the fuero (Biscayan laws, derived from Navarrese and Basque customary rights) that affirmed that the possessors of the sovereignty of the Lordship were the Biscayans themselves and that, at least in theory, they could refute the Lord.

The Lords and later the kings, came to swear the Statutes to the oak of Gernika, where the assembly of the Lordship sits.

Modern age[link]

Bilbao in 1575.

In the modern ages commerce on took great importance, specially for the Port of Bilbao, to which the kings granted privileges on trade with the ports of the Spanish Empire in 1511. Bilbao was already then the main Castilian harbour, from where wool was shipped to Flanders and other goods were imported.

In 1628, the separate territory of Durango was incorporated to Biscay. In the same century the so-called chartered municipalities west of Biscay were also incorporated in different dates, becoming another subdivision of Biscay: Encartaciones (Enkarterriak).

Carlist General Tomás de Zumalacárregui. Zumalacárregui, a Basque, saved the Carlist cause from the brink of disaster in 1833.

The coastal towns had a sizeable fleet of their own, mostly dedicated to fishing and trade. Along with other Basque towns of Gipuzkoa and Labourd, they were largely responsible for the partial extinction of North Atlantic Right Whales in the Bay of Biscay and of the first unstable settlement by Europeans in Newfoundland. They also were able to sign separate treaties with other powers^{[citation needed]}, particularly England^{[citation needed]}.

After the Napoleonic wars, Biscay, along with the other Basque provinces were threatened to have their self-rule cut by the now Liberal Spanish Cortes. This caused the successive Carlist Wars, where the Biscayan government, along with the other Basque provinces supported the reactionary faction.

Many of the towns though, notably Bilbao, were aligned with the Liberal government of Madrid. In the end the wars resulted in successive cuts of the wide autonomy of Biscay and the other provinces. In the 1850s extensive prime quality iron resources were discovered in Biscay. This brought a lot of foreign investment mainly from England and France, which made it one of Spain's richest and most industrialized provinces. Together with the industrialisation appeared important bourgeois families such as Ybarra, Chávarri and Lezama-Leguizamón. The great industrial (Iberdrola, Altos Hornos de Vizcaya) and financial (Banco Bilbao Vizcaya Argentaria- BBVA) groups were created.

Twentieth century[link]

The historic Oak of Gernika, symbol of the Basque institutions.

During the Second Spanish Republic, the Basque Nationalist Party (PNV) governed the province. When the Spanish Civil War broke out, Biscay supported the Republican side against the army of Francisco Franco, of fascist ideology.

Soon after, the Republic acknowledged a statute of autonomy for the Basque Country but, due to fascist control of large parts of it, the first short-lived Basque Autonomous Community had power only over Biscay and a few nearby villages.

As the fascist army advanced westward from Navarre, defenses were planned and erected around Bilbao, called the Iron Belt. But the engineer in charge, José Goicoechea, defected to the fascists, causing the unfinished defenses to be of little value. In 1937, German airplanes under Franco's control destroyed the historic city of Gernika, not before having bombed Durango with some less severity few weeks before. Some months later, Bilbao fell to the fascists. The Basque army (Eusko Gudarostea) retreated to Santoña, beyond the limits of Biscay. There they pacted their surrender with the Italian forces (Santoña Agreement), but these gave them away to Franco. This surrender was seen negatively by the rest of Republican forces, who felt that the Basques had betrayed them.

Under the dictatorship of Franco, Biscay and Gipuzkoa (exclusively) were declared "traitor provinces" and stripped from any sort of self-rule.

Only after Franco's death in 1975, democracy was restored in Spain. The 1978 constitution, accepted the particular Basque laws (fueros) In 1979 the Statute of Guernica was approved and Biscay, Araba and Gipuzkoa formed the Autonomous Community of the Basque Country. The Autonomous Community of the Basque Country has its own parliament.

For all of the recent democratic period the winner of all the elections held in Biscay has been the Basque Nationalist Party. Recently the foral law was amended to extend it to the towns and the city of Urduina, that had always used the general Spanish Civil law.

Geography[link]

Gaztelugatxe, in Bermeo

Biscay is bordered by the community of Cantabria and the province of Burgos (in the Castile and León community) to the west, the Basque provinces of Gipuzkoa to the east, and Álava to the south, and by the Cantabrian Sea (Bay of Biscay) to the north. Orduña (Urduña) is a Biscayan exclave located between Alava and Burgos provinces.

Climate[link]

Untxillaitz, in Urkiola mountain range.

The climate is oceanic, with high precipitation all year round and moderate temperatures, which allow the lush vegetation to grow. Temperatures are more extreme in the higher lands of inner Biscay, where snow is more common during winter.

Features[link]

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.

Administrative divisions[link]

Historical[link]

(Click for full legend).

Historically, Biscay was divided into merindades (called eskualdeak in Basque), which were two, the Constituent ones and the ones incorporated later.

The constituent ones were (the number indicates their position on the map):

• Uribe¹
• Busturia²
• Markina³
• Bedia⁴
• Amorebieta (also Zornotza)⁵
• Arratia⁶

Modern[link]

Map of current municipalities of Biscay.

Currently, Biscay is divided into seven comarcas or regions, each one with its own capital city, subdivisions and municipalities.

These are:

• Greater Bilbao, usually divided into subregions:
  • Bilbao
  • Left Bank
  • Uribe-Kosta
  • Txorierri
  • Hego Uribe

• Mungialdea
• Enkarterri
• Busturialdea
• Durangaldea
• Lea-Artibai
• Arratia-Nerbioi

Population[link]

According to the 2010 INE census, Biscay has a population of 1.153.724, and its population density of 519,9 hab/km, only surpassed by the one of Madrid and Barcelona. In 1981 Biscay was the fifth Spanish province in population, and despite the strong demographic crisis the province has been living since the Transition it is today the ninth province in population.

Government and Foral institutions[link]

The government and foral institutions of Biscay, as a historial territory of the Basque Country are the Juntas Generales de Vizcaya and the Foral Diputation of Biscay.

Juntas Generales[link]

Foral Diputation's building in Bilbao.

The Juntas Generales of Biscay are an unicameral assembly that has normative authority in the province. Its members, called apoderados, are elected by universal suffrage. The elections are held each four years.

After the 2011 elections, the configuration of the Juntas is the following:

Foral Diputation[link]

The Foral Diputation has an executive function and reglamentary authority in Biscay. The Foral Diputation is configured by a General Deputy, who currently is José Luis Bilbao (PNV) and who is chosen by the Juntas Generales and by the rest of deputies.

Transportation[link]

The Cantabric Highway.

Roads[link]

Biscay is connected to the rest of provinces by two main highways, the Cantabric Highway, which connects Bilbao and Durango with the French border, with accesses in Eibar, Zarautz and Donostia (the three of them in the province of Gipuzkoa), and the Basque-Aragonese Highway, which connects Bilbao with Zaragoza via Tudela, Calahorra and Logroño.

As well, many secondary roads connect Bilbao with the different towns located in the province.

Air[link]

Bilbao's airport.

Biscay's main and only airport is Bilbao Airport, which is the most important hub in northern Spain, and the number of passengers using the new terminal continues to rise. It is located in the municipalities of Loiu and Sondika.

Commuter rail[link]

Biscay has different commuter rail services, operated by different companies. Cercanías Bilbao is the commuter rail service "cercanías" offered by Renfe, the national rail company. It connects Bilbao and its neighborhoods with other municipalities and regions inside Biscay, like Barakaldo, Santurtzi, Portugalete, Muskiz, Orduña and others.

Bilbao's main train station.

EuskoTren has three commuter rail lines in the province; all of them start in Bilbao; one connects the city and Greater Bilbao with the comarca of Durangaldea and finished in Donostia (in the province of Gipuzkoa), other line connecting Greater Bilbao with Busturialdea and other serving the Txorierri region. FEVE also offers a commuter rail service connecting the regions of the Greater Bilbao with Enkarterri.

Long distance railways[link]

Bilbao-Abando is Biscay's main train station, with regular trains to other Spanish provinces like Burgos, Madrid and Barcelona offered by Renfe. FEVE also offers long distance trains to Cantabria and the Province of León in the Castile and León community.

The Basque Y is the name given to the future high-speed rail that will connect the three cities of the Basque Country; Bilbao (in Biscay), Donostia (in Gipuzkoa) and Vitoria-Gasteiz in Álava.

Metro[link]

Metro Bilbao is a metro system serving the city of Bilbao and its metropolitan area, the Greater Bilbao region. It connects the city with other municipalities like Basauri, Barakaldo, Santurtzi and Getxo, among others.

Tourism[link]
