Saint-Sauveur-en-Puisaye is a commune in the Yonne department in Burgundy in north-central France.
In the early seventies Château de la Folie, north of the village - halfway Mezilles, was home to one of the "Maharishi’s Science of Creative Intelligence" projects. Transcendental Meditation teachers and students from all over the world gathered here to renovate the buildings and make the château a meditation centre. There were plans to make a campus with meditation-units in the fields between the château and the Etang de la Folie, just beside the D7 road. The project was abandoned in the mid-seventies. Reasons unknown.
It is the birth place of the writer Colette. A museum dedicated to her life and work is housed in her childhood home.
