Antarès, Event venue in Le Mans, France

Antarès is a white, spherical building of about 15,000 m² in the Technoparc Sud district of Le Mans, next to the Stade Marie Marvingt and the Mulsanne Straight of the 24 Hours circuit. Its long curved roof slopes down at the ends above a continuous band of rectangular windows, with a thin blue stripe at the base. Inside, the main hall, named salle Christian Baltzer, holds 3,200 to 8,077 spectators depending on the layout.

Antarès was inaugurated on 25 September 1995 with a concert attended by 5,000 spectators. It was the first venue built by the company Vega and was designed by DMT Architectes. In 1999 it hosted matches of the FIBA EuroBasket, and in 2006 it staged the Match des Champions.

Locals call the building "la soucoupe" (the saucer) because of its white spherical shape. Its name comes from Antarès, the 17th star of the planetary system, a reference to Le Mans being the 17th city of France. The main hall is named after Christian Baltzer, and the arena works alongside the smaller Oasis hall.

The venue provides plenty of seating with good sightlines for all audience areas. It is helpful to arrive early for popular shows to get a good view of the stage.
