Palais de la musique et des congrès, Convention centre and concert hall in the Wacken district, Strasbourg, France

The Palais de la musique et des congrès is a convention centre and concert hall in the Wacken district of Strasbourg, built in glass and concrete in 1973–1975 and renovated and extended in 2013–2016. Its three auditoriums are the Salle Érasme (1,876 seats), the Salle Schweitzer (1,182 seats) and the Salle Cassin (515 seats), alongside ten plenary rooms, fifteen committee rooms and 8,000 m² of exhibition space. A kilometre-long arcade of fifteen-metre steel columns clad in folded stainless steel wraps the complex.

In 1962 mayor Pierre Pflimlin asked Le Corbusier to design a music and congress palace; the architect made drafts and a wooden model but died in 1965 before completing the plans. Built in glass and concrete from 1973, the hexagonal building opened on 16 October 1975 with the 1,876-seat Salle Érasme. A northwest wing added the Salle Schweitzer in 1989, and renovation by Dietrich/Untertrifaller and Rey-Lucquet & Associés, begun in 2013 and delivered in 2016, added the Salle Cassin and a stainless-steel arcade.

The Orchestre philharmonique de Strasbourg has been based here since 1975, when the building opened; its main auditorium, the Salle Érasme, seats 1,876. The complex hosts over 300 events a year, from concerts to congresses and temporary exhibitions, and its name is often shortened locally to PMC. The 2016 renovation added a stainless-steel arcade of fifteen-metre columns that wraps around the complex.

The complex sits in the Wacken district, next to the exhibition park and the European institutions, not in the city centre. Tram lines B and E stop at Wacken, and bus line H at Palais de la Musique et des Congrès. The 2013–2016 renovation added an almost kilometre-long arcade of 15-metre, six-tonne steel columns clad in folded stainless steel, which wraps the whole building.

The 2013–2016 renovation wrapped the complex in an almost kilometre-long arcade of fifteen-metre-high, six-tonne steel columns clad in angularly folded stainless steel. The architects kept the original equilateral-triangle motif and hexagon shape of the 1975 building. The project was nominated in December 2016 for the Mies van der Rohe Award 2017.
