The scaffolding concealing the facade was removed on 15 August 1867 in time for the Paris Exposition of 1867. The official title of the Paris Opera was prominently displayed on the entablature of the giant Corinthian order of coupled columns fronting the main-floor loggia: "ACADEMIE IMPERIALE DE MUSIQUE". When the emperor was deposed on 4 September 1870 as a result of the disastrous Franco-Prussian War, the government was replaced by the Third Republic, and almost immediately, on 17 September 1870, the Opera was renamed Théâtre National de l'Opéra, a name it kept until 1939. In spite of this, when it came time to change the name on the new opera house, only the first six letters of the word IMPERIALE were replaced, giving the now famous "ACADEMIE NATIONALE DE MUSIQUE", an official title which had actually only been used during the approximately two-year period of the Second Republic which had preceded the Second Empire.
