Bougival (French pronunciation: [buʒival] ⓘ) is a suburban commune in the Yvelines department in the Île-de-France region in Northern France.

It is located 15.3 km (9.5 mi) west from the centre of Paris, on the left bank of the River Seine, on the departmental border with Hauts-de-Seine.

[3] Bougival is also noted as the site of the Machine de Marly, a sprawling, complicated[4] hydraulic pumping device that began supplying the massive quantity of water required by the fountains at Palace of Versailles in the late 17th century.

Considered one of the foremost engineering accomplishments of its era, the cacophonous, breakdown-prone[4] apparatus comprised fourteen waterwheels (approximately 38 feet in diameter) driven by the current of the Seine — in turn powering more than 250 pumps, delivering water up a 500-foot vertical rise through a series of pumping stations, holding tanks, reservoirs, pipes and mechanical linkages.

A local monument commemorates the Montgolfier brothers, pioneers of flight;[3] the commune hosts the annual Festival of Bougival et des Coteaux de Seine.
