1. History

Yvelines was created from the western part of the former department of Seine-et-Oise on 1 January 1968 in accordance with a law passed on 10 January 1964 and a décret d'application (a decree specifying how a law should be enforced) from 26 February 1965. It inherited Seine-et-Oise's official number of 78 since it took up the largest portion of its territory. In addition to this, it inherited Seine-et-Oise's prefecture, Versailles.

It gained the communes of Châteaufort and Toussus-le-Noble from the adjacent department of Essonne in 1969.

The departmental capital, Versailles, which grew up around Louis XIV's château, was also the France capital for more than a century under the Ancien Régime and again between 1871 and 1879 during the early years of the Third Republic. Since then the château has continued to welcome the French Parliament when it is called upon to sit in a congressional sitting (with both houses sitting together) in order to enact constitutional changes or to listen to a formal declaration by the President.^[1]

2. Geography

2.1. Situation

Yvelines is bordered by the departments of Val-d'Oise on the north, Hauts-de-Seine on the east, Essonne on the southeast, Eure-et-Loir on the southwest and Eure on the west.

The eastern part of the department, as well as its northern part along the Seine, is part of the Paris metropolitan area, but the rest of the department is rural, much of it covered by the Forest of Rambouillet (also known as the Forest of Yveline, from which the name of the department is derived).

Besides Versailles (the prefecture) and the subprefectures of Mantes-la-Jolie, Rambouillet, and Saint-Germain-en-Laye, important cities include Conflans-Sainte-Honorine, Poissy, Les Mureaux, Houilles, Plaisir, Sartrouville, Chatou, Le Chesnay, and the new agglomeration community of Saint-Quentin-en-Yvelines.

Two regional parks can be found in Yvelines: Haute Vallée de Chevreuse Regional Natural Park and part of Vexin Français Park. Yvelines is home to one of France's best known golf courses, La Tuilerie-Bignon, in the village of Saint-Nom-la-Bretèche.
