ABSTRACT Amidst increasing societal discussion on slavery and colonial heritage, tourism has emerged as a potential avenue to address such concerns. Yet, tourism and tour guiding suffers from a paradox. On the one hand, tourism narratives can form a part of an oppressive strategy in colonial approaches against socially excluded and marginalised groups while on the other hand, tourism can offer counter-narratives with progressive potential in transforming mindsets and enlarging perspectives. This article explores these conceptual issues in the context of guided city tours in Amsterdam utilising a qualitative case study design involving participant observation and interviews. We identify the spatial narratives tour guides use to (re)present slavery and colonial heritage, and the factors shaping these narratives. We make two main contributions to the literature. Firstly, we identify how the need for positive atmosphere and good vibes are central to the extent to which tour guides are willing to engage tourists with slavery and colonial narratives in the city. Secondly, we offer a spatial mapping of slavery and colonial heritage narratives offered on tours through Amsterdam. Our study therefore contributes to evidencing how tourism, and tour guides hold transformative potential in dealing with slavery and heritage in an European urban setting.
