The City That Vanished in 4 Minutes | VAJONT Dam Disaster 1963

VAJONT DAM DISASTER. October 9th, 1963. The deadliest dam collapse in history. The tallest dam in the world — built to tame a valley in the Italian Dolomites. ▶ Watch the full Lost Civilizations playlist: [ADD PLAYLIST LINK HERE] Eight kilometers downstream, Longarone: a quiet mountain town of 4,500 people. Most of them are already asleep. The dam's engineers know the mountain above the reservoir is moving. Locals call it "la montagna che cammina" — the mountain that walks. The engineers have calculated the risk. They have concluded — it will be fine. They are wrong by a factor of twelve. At 10:39 pm — 260 million cubic meters of rock fall into the reservoir in less than 45 seconds. The Vajont Dam holds. It doesn't matter. The water goes over the top. In minutes — Longarone is gone. 1,917 people die. 487 of them children. The dam still stands today. Empty. Never refilled. A monument to what happens when power ignores evidence. This is what Longarone really looked like. The night before the Vajont wave ended everything. Part of our Lost Civilizations series.
