The Ridnaun site is a unique monument to the industrial revolution. Here, 150 years ago, a state-of-the-art ore processing plant was created, with huge machines to break and crush the rock and large flotation pools to convey the ores to the surface. Impressive braking inclines and horse tracks form part of what is the world’s largest above-ground conveyor, leading to the ore district high up in the mountains. The Poschhaus Gallery bores 6 km diagonally through the mountain into the Passeier Valley.
