Nouvelle-Aquitaine shares border with Occitania
Geography
At 84,061 square kilometres, Nouvelle-Aquitaine is larger than French Guiana, which makes it the largest region of metropolitan and overseas France.
Nouvelle-Aquitaine is delimited by four other French regions (Pays de la Loire to the north-west, Centre-Val de Loire to the northeast, Auvergne-Rhône-Alpes to the east, and Occitania to the south-east), three autonomous communities in Spain to the south (from east to west, Aragon, Navarre, and Basque Country), and the North Atlantic Ocean (the eastern part of Bay of Biscay, Golfe de Gascogne in French) to the west.The A10 autoroute (the "Aquitaine") is the major artery between Bordeaux and Paris, commissioned in 1981. It is part of to the network of "autoroutes du Sud de la France" and provides access to several cities: Saintes, Niort or Poitiers. From Saintes, highway A837 allows drivers to reach the town of Rochefort. Further north, in Niort, an interchange provides access to the A83 motorway, the Vendée and Nantes (Pays de la Loire). The N10 is the main road of the Charente and an important road for connecting between Bordeaux and Poitiers including Angoulême.
Connecting the east of Bordeaux (Libourne) to Greater Lyon, the A89 motorway (called "La transversale") irrigates the eastern part of the region, facilitating travel between the cities of Bordeaux and Périgueux, Brive-la-Gaillarde, Tulle and Ussel. A little further south, the D936, which roughly follows the course of the Dordogne, is grafted on the Bordeaux ring road via an interchange at the municipalities of Cenon and Floirac. It gives access to the towns of Branne, Castillon-la-Bataille and Sainte-Foy-la-Grande (Gironde) and Bergerac (Dordogne).
Southwest of Bordeaux, the A63 is a major focus of the regional motorway network. Forming a large artery almost straight through the vast expanses of flat Landes de Gascogne, it crosses the south of Gironde and Landes (passes near Dax but avoids the prefecture, Mont-de-Marsan) before joining Bayonne and the Basque Country, to Irun, on the Spanish border, the main border crossing. The other border crossings, less frequented but less direct, are the Somport tunnel and Col du Pourtalet.
The Basque Country and Béarn are also served by a road parallel to the Pyrenees, which facilitates access to Toulouse and the Mediterranean regions: the A64, called "La Pyrénéenne". It starts from Briscous (in the outskirts of Bayonne), continues to Pau before reaching Tarbes in the neighbouring region of Occitania) and the Toulouse ring road.
The eastern region is well served by the A20 north–south axis between Paris and Toulouse and opens up Limousin. It thus goes through La Souterraine, Limoges and Brive-la-Gaillarde. Another important way, the European route E603 connects Limoges to Angoulême and Saintes. It represents one of the key elements of the road Central Europe Atlantic important channel of communication between the Rhône Valley and the Atlantic coast, which is divided into multiple plots at Angoulême and Saintes (Bordeaux, Royan and La Rochelle).Industries
The region is a major international center in the field of aeronautics and space industry. Together with the neighbouring region Occitania, it belongs to the Aerospace Valley world-class industry cluster. The regional aerospace sector is closely linked to the defence sector, leading to talk of industry "ASD" (aeronautics, space and defence).
The regional aircraft industry is a world leader for business aircraft, high-tech batteries, high performance composite materials, landing gear systems and turbines for helicopters, the European leader for military aircraft, cockpit equipment and systems, ground tests and flight, launchers, solid propulsion, airborne radars and systems, weapons systems deterrence, atmospheric re-entry technology and national leader in the interior design of 'business aircraft, aircraft maintenance, UAV systems.
