The city also has several business parks, including l'Arenas, Nice the Plain, Nice Méridia, Saint Isidore, and the Northern Forum. In addition, the city features several shopping centres such as Nicetoile on Avenue Jean Médecin, Cap3000 in Saint-Laurent-du-Var (the 5th-biggest mall in France by surface area), Nice TNL, Nice Lingostière, Northern Forum, St-Isidore, the Trinity (around the Auchan hypermarket) and Polygone Riviera in Cagnes-sur-Mer. Sophia Antipolis is a technology park northwest of Antibes. Much of the park is within the commune of Valbonne. Established between 1970 and 1984, it primarily houses companies in the fields of computing, electronics, pharmacology and biotechnology. Several institutions of higher learning are also located here, along with the European headquarters of W3C. It is known as "Europe's first science and technology hub" and is valued at more than 5 billion euros. The Nice metropolitan area had a GDP amounting to $47.7 billion, and $34,480 per capita, slightly lower than the French average. Transport Port The main port of Nice is also known as Lympia port. This name comes from the Lympia spring which fed a small lake in a marshy zone where work on the port was started in 1745. Today this is the principal harbour installation of Nice – there is also a small port in the Carras district. The port is the first port cement manufacturer in France, linked to the treatment plants of the rollers of the valley of Paillon. Fishing activities remain but the number of professional fishermen is now less than 10. Nice, being the point of continental France nearest to Corsica, has ferry connections with the island developed with the arrival of NGV (navires à grande vitesse) or high-speed craft. The connections are provided by Corsica Ferries - Sardinia Ferries. Located in front of the port, the Place Cassini has been renamed Place of Corsica. Airport Nice Côte d'Azur Airport is the third busiest airport in France after Charles de Gaulle Airport and Orly Airport, both near Paris. It is on the Promenade des Anglais, near l'Arénas and
