Brief The Tiber: Memory and Flow proposes that collective memory is not static, it is carried, layered, and continuously reactivated by those who pass through the spaces where history occurred. The installation draws directly from Rome’s WWII history: the deportation of the Jewish community, partisan resistance networks, and the use of the city’s underground geography tunnels, courtyards, railway lines, as routes of survival and escape. The installation aims to make visitors active participants in historical memory rather than passive observers, creating a physical and sensory experience of displacement, resistance, and continuity. Description of the project: Projection surfaces are treated with reverse-painted translucent material, allowing images to emerge from within rather than onto the surface, reinforcing the sense of memory surfacing rather than being displayed. The light patterns are active as visitors pass through. On the River as Metaphor The Tiber here does not erase, it carries. Memories fade visually on the arch as visitors pass, but the patterns that show on the walls remain briefly illuminated behind them, suggesting that passage leaves a trace even when the image disappears.
