This report examines the 2016–17 phase of the cultural mediation project “Passeuses et passeurs de culture: Dare to Approach Art Differently!”, jointly organized by the Lausanne Cantonal Museum of Fine Arts and Pro Senectute Vaud, and coordinated by Sandrine Moeschler and Anne-Claude Liardet. Situated within the broader transformation of cultural mediation practices in Switzerland since the early 2000s, the project conceptualizes the museum as a space for intergenerational interaction and non-professional voices. It invites older adults and students in training to develop familiarity with museum exhibitions and become “culture transmitters”, notably by leading guided tours for guests of their choosing. Adopting a self-reflective approach, the report evaluates the project’s strengths and limitations based on observations of group sessions and participant testimonials. The findings show that the project supports individual transformation (confidence, expression, cultural agency) and encourages the institution to reconsider its mediation frameworks, even as it partly reproduces institutional discourse norms. The analysis also highlights that most participants possess a high level of cultural capital, which restricts social diversity within the program. The issue of whether the model can be adapted to other institutions is discussed: success depends on the quality of interpersonal relationships and on institutions’ willingness to share interpretive authority. Finally, the guided tours designed by participants are identified as a valuable site for studying how non-professionals reinterpret museum discours
