This article synthesizes original comparative perspectives of visibility, (counter)actions, and legacy regarding queer monuments: public artworks dedicated to, and questioning or queering normativities around, the lives of LGBT+ people. It pursues a dialogic, interdisciplinary, and multisite and intercultural argument, drawing from approaches and preliminary insights from a scholarly project (Queer Memorials) and artist's project (Strange Inheritance) with topical case studies covering North America and Europe. After abductive ethnography, the analysis oscillates between theory/ literature and scholarly and creative practice. It attends to the critical roles queer monuments have played in engaging with how sexual "others" have fallen in and out of place through social struggles, radical politics, and collective memory. The peer exchange provides a cross-case taxonomy of queer monuments' roles, navigating between sorrowful, celebratory, provocative, and informative types and values. It advocates both arts-based enquiry and practice as grounded pathways for narrating queer monuments' activist potential to memorialize, and visibilize, sexual and gender minorities and their overlapping rights in/to space.
