•Post-secular pilgrimages, polyvalent mobilities, re-workings of place identity.•Post-secular pilgrimages in the making of post-secular religious experience-spaces.•Pilgrimages as instances of post-secular journeys of becoming. Current debates on and theorizations of (post)secularism lack sustained discussions of the role of pilgrimage tourism, spiritual journeys and sacred places. This article is a theoretically informed and empirically based study that explores contemporary pilgrimage tourism as an arena where ‘post-secular’ praxis and discourse fuse. It identifies the multiple ways in which the ‘post-secular’ is performed through pilgrimage tourism, viz. construction of identities, journeys of becoming and performativity as instances of mobile place making. Contemporary pilgrimage tourism to Santiago de Compostela is polyvalent. Pilgrimages cannot be read off as unambiguously religious, secular or post-secular. Pilgrimage tourism spaces are open-ended such that place identity and meaning are being continuously reworked.
