Alpexpo, Convention center in Grenoble, France.

Alpexpo is a convention center in Grenoble featuring extensive glass and steel structures divided into distinct zones: Alpes Congres for conferences, Exhibition Park for trade shows, and Summum for performances and events. The separate halls allow the venue to accommodate multiple activities at once and host everything from intimate seminars to large international exhibitions.

Alpexpo was designed by Jean Prouvé with his sons, including Claude Prouvé, and built on the site of the former Grenoble-Mermoz airport. Its structure was finished in December 1967 and the fittings in early February 1968; it first received visitors on 6 February 1968 during the Winter Olympics, when its hall held luxury shops and a temporary Europe 1 radio studio. From 24 March 1968 it took over Grenoble's exhibitions with the 11th international winter sports fair.

The main hall has been named Jean Marandjian since 1996, after the venue's former director. In the 1970s and 1980s, before Le Summum opened in 1988, the halls were Grenoble's main venue for contemporary music, hosting AC/DC, The Cure, ZZ Top and Scorpions. The abstract steel sculpture Germinal by Claude Viseux stands near the entrance, and the Olympic mast from the 1968 opening ceremony occupies the roundabout by the main access.

Alpexpo stands along avenue d'Innsbruck on the site of the former Grenoble-Mermoz airport, with a 4,000-space car park plus the lots of the Grand'Place shopping centre next door. The main hall, named Jean Marandjian since 1996, has ceilings at least 7 m high, rising to 8.5 m between supports spaced 36 m apart. The roundabout at the main entrance holds the Olympic mast from the 1968 opening ceremony.

The abstract steel sculpture Germinal by Claude Viseux, a 2.5-tonne stainless-steel sphere with levitating elements, was placed near the entrance for Grenoble's first French sculpture symposium in 1967. The roundabout at the main access still holds the Olympic mast from the 1968 Winter Games opening ceremony.
