Longarone, or rather new Longarone, was born on the rubble of one of the worst environmental disasters in history. A piece of mountain landslides into a dam basin, which resists the impact and produces an anomalous wave that hurls itself downstream with unprecedented violence, sweeping away everything in the existing inhabited area and human lives. All while people were sleeping. Fabio d'Arsie uses photography to relate to built space and, therefore, to represent it. The images in this selection help us to "reconstruct" Longarone and read about its renewed building and urban face, which projects us explicitly into the second half of the twentieth-century topography. It's evidence of the irreducible "sapiens" will that manifests itself in the mathematics of addition and in building even on tragic foundations. The dam with its concrete cantilever is still up there, squeezed between the Vajont Valley's rocky slopes, weighing on its inhabitants' memory. A new town which, despite the modern impetus of the reconstruction plan entrusted to Giuseppe Samonà, is, in fact, a memorial. A place of remembrance. So we ask ourselves whether memory can survive when collectivised or "monumentalised." Yes, it is possible, as long as it is not eroded by time like a cliff exposed to the indifferent furies of the ocean. Today, over 50 years after the destructive epilogue, there is still a lot of talk about that event, the causes, and little about the consequences. So, the memory is alive but more like an act of speculation of a history limited to aesthetic paralysis or temporal sclerosis.
