Exposed to temporal and natural decay, these sites of the past retain, in their dissipating image, the sense of unease described by Sigmund Freud when defining the uncanny: an expression of both the familiar and the frightening, which disturbs the gaze and leaves the observer in a ‘threshold’ state between the known and the repressed. The oblivion of our time, which constantly looks to the past in order to preserve human memory without losing it, is the result of the liminal stage we experience daily: uncertain and uneasy in the face of a predictable yet uncontrollable present.
