  SOLD OUT

  The Fondation Singer-Polignac is exceptionally opening the doors of its private mansion to the public on Saturday, September 20, as part of the European Heritage Days. This mansion was the former home of Winnaretta Singer, Princess de Polignac (1865-1943), a great patron of the arts and sciences. The foundation she created has been based here since her death.

  Here you can discover her music salon and state salons on the 1st floor, as well as the princess's former studio, where she painted and played the organ by day and held her musical salons in the evening. Gabriel Fauré, Vincent d'Indy, Nadia Boulanger and Igor Stravinsky, as well as Marcel Proust, Jean Cocteau and Colette, regularly walked the halls of this hotel.

  The guided tour will also reveal some of the princess's rare surviving archives.

  Today, the Hôtel de la Fondation welcomes artists from the world's leading conservatories on a daily basis, enabling them to rehearse in a number of specially equipped rooms since the creation of a musical residence in 2006. You may well come across some of these musicians in a corridor.

  Once a month, the foundation produces concerts reserved for professionals and patrons from the musical and cultural world, to give the artists in its residency a chance to make a name for themselves. Throughout the year, cultural and scientific days are also organized in collaboration with leading universities and research centers. All of these events are broadcast online and available by invitation only.
