The trilogy The Walls Don’t Speak (Les murs ne parlent pas) is the result of a three-year dialog between the photographer Jean-Robert Dantou, and an interdisciplinary Social Sciences team coordinated by the anthropologist, Florence Weber. The photographer set up his studio in various institutions (psychiatric nursing homes, private clinics, psychiatric hospitals) as well as beyond their walls, working directly with patients, friends, family and caregivers on images which mean something to them.
