The originalStade Louis II was opened in 1939 as the home ofAS Monaco. The decision to build a new sports centre in Monaco dates back to 1979.Prince Rainier III decided to establish a sports area in the Fontvieille district. The prince brought in Parisian architects to build the complex. The work began in May 1981 and ended in 1984, and required 120,000 m³ of concrete, 9,000 tonnes of iron and 2,000 tonnes of steel structure on a median land reclaimed from the sea. The complex was inaugurated on 25 January 1985 by Rainier III.
The stadium has a current seating capacity of 16,360 (almost half of the country's population), and is named afterLouis II, Prince of Monaco, who was theSovereign Prince of Monaco when the original stadium was built. The vast majority of the stadium's facilities are located underground, including theGaston-Médecin multi-sports centre, the Prince Albert II aquatic centre and a large car park directly under the pitch.
The stadium complex, besides the football stadium and athletics track and the Salle Gaston Médecin, also contains the aquatic centre Prince Albert II, a large office complex, and also houses theInternational University of Monaco (IUM), which specializes in business education.
