The Forêt de Marly (known as the forêt de Cruye until the 18th century) is a 2000 hectare forest estate in Yvelines, between Saint-Germain-en-Laye and Versailles about 15 km to the west of Paris. It is about 12 km long east to west, over the communes of Louveciennes, Marly-le-Roi, Saint-Nom-la-Bretèche, Feucherolles and others. Historically, it was a hunting estate of the kings of France, then of the presidents of the Republic, but (since 1935) is now divided along its whole length by the A13 autoroute.
