IRCAM - Paris
Place Igor Stravinsky, Paris

The Ircam (Institut de Recherche et Coordination Acoustique/Musique) is an institute for musical research. It promotes the collaboration between scientists and musicians,
and is considered to be  a ‘musical instrument on an urban scale’. It was inaugurated in 1978 as part of the Centre Pompidou development.
At this time the Ircam was entirely underground, located under the fountain designed by Niki de Saint-Phalle and Jean Tinguely on the Place Igor-Stravinsky.
The underground construction consisted of three levels of highly flexible spaces to facilitate research and experimentation.
The ceilings, floors and walls are all mobile so that volume and acoustics for musical performances can be modified. In 1990 the Renzo Piano Building Workshop
added a six-storey tower for the institute’s offices, giving the hidden building a visual presence and relationship to the Pompidou Centre opposite.
The building is located on the corner of the Piazza. The elevations of the building are marked by large window areas and closed panels made of terracotta.
