Stade Louis II

The first Stade Louis-II opened in 1939, built by the reigning prince Louis II, and held 13,000. It was AS Monaco's home and carried the name the present ground still uses. The decision to replace it with a new sports centre dates from 1979, when Prince Rainier III settled on a site in the Fontvieille district and brought in Parisian architects to design the complex. Given the size of the principality the brief was multi-sport rather than football alone, and the choice was made to build only 20,000 places, a figure weighed against Monaco's population on one side and the requirements of European competition on the other.

Work began in May 1981 and finished in 1984, on a platform won from the sea. It took 120,000 cubic metres of concrete, 9,000 tonnes of iron and 2,000 tonnes of steelwork. The nine arches at the away end that identify the ground were designed for ventilation, and stand as the aesthetic signature of the architect, Henri Pottier. Most of the complex went underground: the Gaston Médecin multi-sports hall, the Prince Albert II aquatic centre and a car park directly beneath the pitch, which sits 8.35 metres above road level on the car park roof.

Rainier III inaugurated the complex on 25 January 1985, and AS Monaco played their first match on the new ground the next day, beating RC Lens 3-0. The old stadium was then demolished, and the Fontvieille shopping centre, two museums and a multi-purpose hall were built over the ground it had stood on.

AS Monaco, a professional club affiliated to the French Football Federation and playing in the French competitions, has used the ground since it opened. It took the European Super Cup final in 1986, played over a single match on neutral soil for reasons given as political, and then held the fixture for fifteen consecutive editions from 1998 to 2012. International sides have rarely appeared: two matches of a friendly tournament in 1988, among them Switzerland against Austria. Professional boxing has come to the stadium from time to time for world title fights, Julio César Chávez Sr against Rocky Lockridge among them, and the ground also stages the finals of the Challenge Prince Rainier III, the principality's main competition for Monegasque amateur company teams.

The Herculis athletics meeting has been held at the stadium since 1987. It ran in the Golden League from 1998 to 2002 and has been part of the Diamond League circuit since 2010, and a world record has been broken at the meeting. The ground took the world athletics finals in 2003, 2004 and 2005, and the athletics events of the Games of the Small States of Europe in 1987 and 2007, with the 2027 edition also due here. Under the stands, the Salle Gaston Médecin carries basketball, volleyball and handball as well as judo, fencing, weightlifting and gymnastics, and has held Monaco's international judo tournament since 1993; its 2,500 seats became about 3,000 in a refit in 2016 and then, after enlargements in 2022 and 2023, 5,000.

Muse played the stadium on 12 July 2007 on the Black Holes and Revelations tour, and the Eagles played there during the wedding of Prince Albert II and Charlène Wittstock. On 28 March 2026 Pope Leo XIV said Mass to a full stadium on his visit to the principality. An electronic scoreboard tied to the electronic timing system has given spectators instant results since 2008. The pitch, resting as it does on the roof of the car park, has caused AS Monaco persistent trouble, to the point that the club uses a mobile lighting rig that reproduces sunlight over the grass; its condition drew particular criticism at the start of the 2024-25 season.

The complex belongs to the state of Monaco and holds AS Monaco's administrative offices, a number of Monegasque government departments and the International University of Monaco, a private English-language business school. The club's academy, founded in 1975, sits outside the principality at La Turbie in France. Seating 16,360, close to half the population of the country, this is Monaco's only football and athletics ground.
