Yvelines


Yvelines is a department in the western part of the Île-de-France region in Northern France. In 2019, it had a population of 1,448,207. Its prefecture is Versailles, home to the Palace of Versailles, the principal residence of the King of France from 1682 until 1789, a UNESCO World Heritage Site since 1979. Yvelines' subprefectures are Saint-Germain-en-Laye, Mantes-la-Jolie and Rambouillet.

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 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.
Yvelines derives its name from the Forest of Yveline, next to Rambouillet.
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 French 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 in order to enact constitutional changes or to listen to a formal declaration by the President.
