Place Moulin Dam is one of the largest dams in Europe and is in Bionaz, in Northern Italy. The 678 m long and 155 m high arch dam was constructed between 1955 and 1965 and has an artificial reservoir capable of holding 105 million m<sup>3</sup> of water.
The dam has a 137 km<sup>2</sup> catchment basin, with nearly 20% of it being made up of glacier run offs. The dam has a 47 m thick base and 6.43 m thick summit, designed to ensure easier inspection. The dam also has two perimeter tunnels and eight horizontal tunnels allowing for technicians to easily walk through them for inspection. The reservoir was first filled in 1967.
