This article addresses the problem of conserving the personal memories that artefacts, in collections held by traditional museums, elicit in the minds of ordinary people who recognise them and relate to them. The focus is specifically on art museums with religious objects. Using a museum in the Netherlands as a case study, we explore how the systematic collection of intangible religious heritage can be pursued. We present the results of several experiments conducted between 2011 to 2016 in collecting personal narratives from visitors who attended four popular exhibitions based on religious themes: pilgrimage, religious women, charity, and sainthood. The article concludes with policy-oriented advice regarding museum strategy, including the importance of recruiting volunteers, sharing narratives in a sustainable way, and putting digital technology to good use.
