The castle is called 'La Conciergerie'. It's one or the most iconic of the révolution., with 'The Bastille '. Bastille was completly destroyed after the fallen of the royalty. Conciergerie survive, and become a terror place where hundreds where executed for their connections to royalty, including Mary Antoinette... Gojira is a perfect choice to represent the chaos of révolution...
Maybe let's add that Marina Viotti the Opera/experimental singer, who's not a member of Gojira, is also not a stranger to French Metalheads as she has had 2 French bands!
I saw this maybe 50 times ! French Revolution, first Republic... Emmanuelle Favre was responsible for scenography in the artistic direction team of all ceremonies in Paris, she is the one who made the stage for Mylene 2019 and Nevermore. The futuristic aspect of the closing ceremony has Cleary smtg to do with La Defense Arena 2019 ;) Love Those olympics were beautiful, very French haha :)) btw Mylene refuses to be part of the ceremony but the played a remix of Désenchantée during the dancing part of the opening ceremony (with fashion icons and drag queens ;)))
Nit far from the building is Le Bataclan where there was a massive terrorist attack I 2015 during a metal band convert. The boat is the symbol of Paris that was used in 2015 after the attacks. Fluctuat nec mergitum : get rocked but does not sink.
Nous assumons notre Histoire, même si elle a été sanglante. Ce sont des faits Historiques qui nous ont donné notre devise : "Liberté, Egalité, Fraternité".
The song " Le ça ira !" sung by Marie-Antoinette at the beginning is a famous song by Edith Piaf : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bzu01gO3pi4.htmlsi=mV4hFGNv2uVn47R- It's from the movie "Si Versailles m'était conté".
