Étangs de Hollande, Artificial lake chain in Yvelines, France

The Étangs de Hollande are six artificial ponds aligned northwest to southeast over five kilometres in the Yvelines, on the communes of Les Bréviaires and Le Perray-en-Yvelines. Cross dikes separate them and carry valves that regulate the water level. The two central ponds, Bourgneuf and Corbet, are only partly flooded, with woods, meadows and a connecting canal. The chain sits at 174 metres, the highest point of the system that fed the fountains of Versailles.

The ponds were created in the 17th century to supply water for the Palace of Versailles, feeding its fountains and water features. Over time, they shifted from this practical purpose to become a place for recreation and leisure rather than serving the royal household.

The name "Hollande" likely derives from Orlande, an old local castle; a 1601-1608 hunt map at Fontainebleau reads "Holande Relais". Louis XV hunted the surrounding forests and from 1755 had Jacques-Ange Gabriel build a hunting pavilion that became the château de Saint-Hubert, demolished in 1855; only its terraced outline remains on the north bank of the Étang de Saint-Hubert.

The six ponds stretch 5 km northwest to southeast between Les Bréviaires and Le Perray-en-Yvelines, separated by cross dikes that carry paths and regulate water through valves. The two central ponds, Bourgneuf and Corbet, are only partly flooded, with woods, meadows and a linking canal. Swimming, fishing and walking are practised around the chain; the water level is held at 174 m, the highest in the Versailles supply network.

The ponds sit at 174 m, the highest point of the hydraulic network that fed the Versailles fountains entirely by gravity, without any lifting machinery. Louis XV hunted the surrounding forests and from 1755 had Jacques-Ange Gabriel build him a hunting pavilion that grew into the Château de Saint-Hubert, demolished in 1855; only its stepped terrace remains on the north bank of the Étang de Saint-Hubert.
