Garnier Opera, in the Palace Secrets

The Opéra Garnier is one of the greatest monuments in Paris. The palace has indeed about 12 kilometers of corridor, of which the third is practically not gained. Only its chief concierge, who has worked there for 33 years, knows every corner of it. He is notably the only one to be able to access one of the most secret places of the opera, a huge underground pool of 54 meters by 45, located six levels below the stage.
