Bougival is the site of the Machine de Marly, a sprawling, complicated hydraulic pumping device that began supplying the massive quantity of water required by the fountains at Palace of Versailles in the late 1600s. In use until 1817, the machine was subsequently updated, replaced with another pumping building in 1858 and finally replacemed by an electrical generator in 1963. The building itself remained until 1968. Remnants are visible today at the riverbank.
