This article investigates carceral heritage sites and gay male experiences, challenging the singular narratives often imposed on these spaces. It explores how visitors might experience these sites as queer spaces and considers the potential impact of these perceptions on both historical and current inmates. In doing so, it introduces the novel concept of 'sites of consciousness-raising' to reimagine heritage sites related to prisons as catalysts for social, legal, and political action. Drawing on diverse sources, the research examines three key aspects of queer carceral heritage: evidence of physical presence, ephemeral materiality, and heritage sites as spaces of encounter. Blending theoretical heritage perspectives with historical analysis it aims to contribute to a more equitable and inclusive understanding of carceral heritage.
