Machine de Marly

The Machine de Marly, also known as the Marly Machine or the Machine of Marly, was a large hydraulic system in Yvelines, France, built in 1684 to pump water from the river Seine and deliver it to the Palace of Versailles.

King Louis XIV needed a large water supply for his fountains at Versailles. Before the Marly Machine was built, the amount of water delivered to Versailles already exceeded that used by the city of Paris, but this was insufficient, and fountain-rationing was necessary. Ironically most of the water pumped by the Marly Machine ended up being used to develop a new garden at the Château de Marly. However, even if all the water pumped at Marly had been supplied to Versailles, it still would not have been enough: the fountains running à l'ordinaire required at least four times as much.
