The Archives nationales, France preserve the national archives of the French state, apart from the archives of the Ministry of Defence and the Ministry of Foreign Affairs, as these two ministries have their own archive services, the Service historique de la défense and the Archives diplomatiques respectively. The Archives nationales have one of the largest and most important archival collections in the world, a testimony to the very ancient nature of the French state which has been in existence for more than eleven centuries already. The archives relocated to Pierrefitte-sur-Seine from 2013.
