On the night of 9 October 1963 the deadliest landslide recorded in European history brought Mount Toc's flank to collapse into the Vajont hydroelectric reservoir, triggering a monstrous 250m high tsunami wave that plunged into the Piave valley below at an impressive speed, wiping out five villages in a matter of minutes. Another tsunami wave traveled into the reservoir's lake and canceled small hamlets on the lake's shores. Of 1910 victims, only 1464 bodies (or parts) were recovered, only 700 were identified. This presentation will illustrate the historical process of establishing the first main site for burials, and how it underwent structural modifications to account for all victims, how the dead are commemorated in other minor cemeteries in the area. The monumental cemetery at Fortogna as well as the memory of the disaster were and remain a terrain of contention for multiple identities.
