Château de la Muette

The Château de la Muette (French pronunciation: [ʃɑto də la mɥɛt]) is a château located on the edge of the Bois de Boulogne in Paris, France, near the Porte de la Muette. It is the OECD's headquarters.

Three châteaux have been located on the site since a hunting lodge was transformed into the first château for Princess Marguerite de Valois, favorite daughter of King Henry II, sister of Kings Francis II, Charles IX and Henry III and the first wife of King Henry IV, in the 16th century. The first château was extended and substantially reconstructed by Louis XV. Louis XVI and Marie-Antoinette lived at this second château, and the first manned flight, in a hot air balloon, set off from the château in 1783.

The old château was demolished in the 1920s to make room for substantial houses, including a new château built by Henri James de Rothschild, which now serves as the Organisation for Economic Co-operation and Development's headquarters.
