We analyze the visual, verbal, and material arguments present at the European Green Belt (EGB), a contemporary
conservation project built from the former Iron Curtain. The EGB presents itself as a “living memorial” that fuses together
former warring countries and thus makes an argument for the unity of Europe. To analyze this incredibly diverse and rhetorically
significant project, we put the digital representations of the site and the discourse around the EGB into conversation with
situated, rhetorical criticism performed along the EGB site itself. We analyze the EGB’s different argumentative juxtapositions
regarding history and memory, nonhuman nature and technology, peace and war, memorial and tourism, and preservation and restoration.
Overall, we find that the transformation of the Iron Curtain from divisive border into a European-wide, transboundary biodiversity conservation project
uses transcendence as a key argumentative structure, which has implications for how we understand the human relationship with the
environment, history, and memory
