Created in yellow Jeumont stone by Ricardo Bofil, the Catalan Neo-Classical architect, on the site of the former arsenal, some parts of which have been preserved. While the Church of Saint-Pierre-aux-Nonnains and the neighbouring Chapel of the Knights Templar are used for concerts of ancient music, this complex is a music and arts centre, whose fine acoustics received the praise of Rostropovitch at the inauguration concert in 1989.
