On 19 October 1900, a current capture fault between the contact shoe on the train and the third rail resulted in a short circuit that started a fire.

Ezra Pound wrote in 1914 that his famous Imagist poem, "In a Station of the Metro", was inspired by his impressions upon exiting a train at Concorde three years earlier.

[5] The original Nord-Sud decor of line 12's station was removed in 1991 when it was redecorated by a new artwork by the artist Françoise Schein.

It consisted of blue letters set on a white square tile that form the text of the Declaration of the Rights of Man and of the Citizen.

Numerous metro stations around the world have also been designed with the same theme in mind by the same artist such as: Luz in São Paulo,[7] Parvis de Saint-Gilles in Brussels,[8] Parque in Lisbon,[9][10] and Westhafen in Berlin.
