In this essay, we critically reflect upon the ephemeral nature of theatre. Such a reflection becomes particularly important in participatory refugee theatre, since the process of participants' bearing witness to experiences of trauma and violence is emphasised as the core impetus. To this end, we investigate the experiences of Syrian young adults participating in a theatre project in Belgium. We argue that the ephemeral nature of theatre enables a potential to initiate reparative pathways of bearing witness by creating a space that may hold both remembrance and forgetfulness, as well as distance and interconnectedness. In a final section, we discuss the implications for theatre practice.
