Yvelines Castle

Yvelines  is a French department in the region of Ile-de-France. Yvelines was created from the western part of the defunct department of Seine-et-Oise on 1 January 1968 in accordance with a law passed on 10 January 1964 and a decret 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. It gained the communes of Chateaufort and Toussus-le-Noble from the adjacent department of Essonne in 1969. The departmental capital, Versailles, which grew up around Louis XIV's chateau, was also the French capital for more than a century under the Ancien Regime and again between 1871 and 1879 during the early years of the Third Republic. Since then the château has continued to welcome the parlement when called upon to sit in a congressional sitting, jointly with the upper house in order to enact constitutional changes or, as happened most recently in June 2009, to listen to a formal declaration by the president.  Source
