The Maurice Ravel Auditorium is a concert hall located in Part-Dieu, the 3rd district of Lyon.
[2] The building was built without an acoustic study which resulted in the volume being too low for symphonic purposes, with a reflective concave back wall.
Eventually a Phillips acoustic enhancement system was fitted to help with sound coverage and reverberation.
Because of the time constraints of the contract he did not have time to build one from scratch and had to use an uncompleted three-manual organ originally intended for the Church of Notre Dame in Auteuil, a district in the northwestern area of Paris, as the basis for the new instrument.
The organ moved to the Palais de Chaillot when the Trocadéro was demolished and was ultimately bought by the government of Lyon for the Auditorium.
