Postcolonial Macau is keen to celebrate its colonial legacy to preserve its cultural distinctiveness. This study explores the reordering of a Portuguese colonial site, the Village of Our Lady in Ka Ho, into an architectural heritage in the broader postcolonial context. Employing the Foucauldian concept of ‘other spaces’, specifically ‘utopia’ and ‘heterotopia’, the study argues for the heterotopic nature of heritage. It identifies the discourses and material representations of heritage, their construction and their mirroring of mainstream social ideals. Heritage as heterotopia is a conceptual entity that informs and is realised with material objects. The discourse takes heritage spaces as mediums for performances through symbolic loading on material objects to demonstrate the space's otherness. In addition, colonial nostalgia emerges as a dominant narrative in shaping urban identity. The primary proposition of this research is that heritage is made through othering, and the otherness of heritage is presented through performing. Heritage‐making transforms the site from a ‘heterotopia of deviation’ to a ‘heterotopia of performance’, which reveals the societal transition from early modernity that advocates for scientific knowledge to postmodernity that embraces neoliberalism, and then to the arriving era of post‐postmodernity based on performatism.
