[3] In 1785 the whole of the château estate (the Domaine de Saint-Cloud), including the pavillon, was acquired by Marie Antoinette, the queen of Louis XVI.

[3] During the French Revolution (1789–99), Breteuil fled from France, and the state took ownership of the pavillon.

[2] In 1875, the Diplomatic Conference of the Metre in Paris, which had been convened by the French government to try to reach an agreement on international collaboration for the maintenance and development of the metric system, established the International Bureau of Weights and Measures (BIPM).

[3] Following an agreement signed on 25 April 1969 with the French government, functional privileges and immunities were granted to the BIPM as an international organisation operating on the site of the Pavillon de Breteuil.

Since 1900, the building has been listed as part of the Domaine national de Saint-Cloud as an historic monument in France.
