Addressing the recent call to rethink history as a form of presence, the essay works toward a recovery of a space in which such presence of history is encoded. I argue that history as a form of active perception is akin to virtual witnessing of the past in the moment of our encounter with historical artifacts, be they texts, photographs, or buildings. To this end, I engage with the conceptual and material aspects of historical perception, deriving a model of history as 'inhabited ruins,' the way it emerges together with historical consciousness and finds an especially dynamic expression in Georg Simmel's philosophy of culture. Throughout, I work with the notion of distance and trans-dimensional presence as the forces that shape and reshape historical awareness. Ruins, intimately connected to the modern historical imagination, are approached not as sites of commemoration or nostalgia, but as spaces of active exchange between presence and disappearance. As such, they are taken to be the models for the transitive character of history itself, blurring the division between perception and thought. In other words, ruins are taken as structures that evoke and summon the past to an encounter with contemporary reality-a type of co-appearance that opens the possibility of virtually witnessing the past. I conclude that the logic of 'inhabited ruins' constitutes the event-horizon of modern identity, always placing history right at the threshold of fragmentation.
